How to disassemble a case on a tablet with a keyboard. What's inside a Chinese "keyboard" tablet case? Tablet interaction

Some time ago, I already posted a review of the Cube WP10 phablet based on Windows 10 Mobile. The purpose of the experiment was to investigate the possibility of using a large-screen phablet as an alternative to a full-fledged netbook or tablet for short trips.
If you have to work with text and / or documents, then it is quite problematic to do this without a keyboard - the screen version covers most of the document area, therefore, in addition to the tablet, a keyboard was ordered - of course, Russified and (so that the experiment does not turn out to be too expensive) the cheapest.
For the results of a dubious experiment, welcome under cat.

I’ll make a reservation right away: if a Windows tablet is quite capable of replacing a laptop when it comes to undemanding tasks (for example, working in MS Office, web surfing, etc.), then a phablet is still just a phone with a large screen, and its functionality is limited on the one hand both by the system used (Windows 10 Mobile is quite far from the desktop version) and by the purely technological characteristics of the device - at least the presence of communication connectors and the ability to connect external peripherals. Another caveat - I can’t say anything about interacting with Android, because I just didn’t have experience with this platform, no matter how good it is.

My experience is that editing, and even viewing any office documents on your phone, is pornography worse than the results of the query "dwarf with a donkey" on PornHub. Firstly, it's just inconvenient - the screen is too small, the number of controls is limited, and at the same time they occupy a significant area of ​​the screen. Secondly, even in native MS Office Mobile applications, the display of documents is not identical to the desktop version: somewhere the font size “floats”, somewhere the location of objects integrated into the document; the performance of macros is generally a separate conversation.
Nevertheless, the main part of applied tasks is reduced to simple tables and, again, simple text documents. When the task is to review and correct them on the fly, any aids will come in handy.
I was hoping that with the help of the mentioned phablet and an external keyboard, I would be able to find just such an intermediate solution, which would avoid the need to carry around a full-sized tablet with a keyboard (that's more than 1.5 kg net weight).

Let's see what came of it.

So, the product in question is one of the cheapest keyboard cases that I managed to find on AliExpress (if we take into account the Russian-language layout).
It is a universal solution, which, in theory, should be suitable for any device with a size of 7-8 inches. The tablet/phablet is attached to the cover using plastic clips, which, in turn, are attached to the cover using tight rubber bands.
The keyboard is connected to the phablet with a Micro USB cable.
The weight of the cover is a little more than 300 grams, according to the seller (I don’t have my own scales to check).



The keyboard case that arrived was packed in ordinary polyethylene, without any pimply film or other additional protection. In my case, it did not seem to be affected by the shipment, but, judging by the comments of the buyers, there were other cases - when, for example, some of the keys came separately from the rest of the product.
At the same time, the execution itself leaves much to be desired - the keys are a bit crooked, and in general the geometry of the keyboard plane is far from ideal.



The size of the case, to be honest, depressing. It is made (clearly, the price speaks for itself) from the cheapest dermantin, stitched (pun?) with white threads. The thickness of the part where the tablet is attached is about 5 mm, the flyleaf is 4 mm, the part of the cover with the keyboard is 9 mm.
To fix the cover in the closed state, there is a “hook” with a magnet; a stand is provided for surface mounting; its angle is not adjustable, since its fixation in the open state is carried out by the most elementary method - by cutting a nylon ribbon of a fixed length. The stand, like the "lash", is fixed in the closed state on the cover with a magnet.

Together with the phablet inside, the design has the dimensions of a medium-thick book with a hardcover - approximately 14.5 x 23 cm, in thickness - 3 cm (excluding the stand and the closure latch) and 4 cm, if you count at the "thickest" place including the stand and fixative. This, however, is still easier to pack in a shoulder bag than a tablet.



Considering the size of the entire device, the keyboard is of course smaller than a full-sized one. Its dimensions are only 202 x 79 mm. It happens, of course, and less (hello Blackberry!), But you can get used to it. The situation is worse with the location of a number of keys - for example, the Russian "X", "b" and "E", whose place on the standard keyboard is well known, have been moved to the bottom row to the right of the space. There is no trouble for English-speaking users - they have service symbols on these buttons that are used infrequently. We, the Slavs, have one inconvenience.
Above the keyboard there are green LEDs indicating the status of CapsLock, ScrollLock and NumLock.

The Micro USB cable that connects the keyboard to the phablet looks rather flimsy. However, it performs its function: the connected keyboard was identified by the system without any problems. Then the "battle" check began.
The first difficulty I encountered was language switching. The standard and familiar Alt-Shift combination does not work on Windows Mobile. The search showed that a different keyboard shortcut works for Win10 Mobile, namely WinKey+Space. But there is no WinKey on the keyboard. In the comments to the order, I saw that I'm not the only one who finds it difficult to switch the language. And he already considered the experiment to be completed ahead of schedule, but empirically calculated that the WinKey function on this keyboard is performed by the “Zzz” key, which, obviously, in other cases serves to put the device into sleep mode.

So, let's start testing the office suite.
Microsoft Word Mobile in terms of use, it turned out to be the closest to the desktop version. This is if you do not set the goal of actively using menu items. If we are talking about "squealing" the text of the treaty, then the task turns out to be quite feasible. The usual "hot keys" work (copy and paste: Ctrl-C / V / X, formatting: Ctrl-B / U / I and Ctrl-R / L / E), open a document (Ctrl-O), repeat an action (Ctrl -Y), etc... You can navigate through the text of the document using the arrows, which, in combination with the Fn key, perform the functions of the PageDn / PageUp / Home and End keys.
Appears, by the way, and the ability to habitually switch between open applications using the Alt-TAB combination.
The Fn key, by the way, is not located very well: usually Ctrl is in its place, and fingers habitually choose it when you need to perform an operation using shortcuts. But let's assume we can get used to it.
You can, of course, control your fingers using the touchscreen of the phablet. At the same time, the on-screen keyboard sometimes pops out, blocking the entire useful plane of the document.

In general, with a lot of reservations, using MS Word Mobile with a keyboard is more convenient than without it.
We will assume that in this part of the experiment is completed in favor of the device.

MS Excel Mobile from the very moment the document is opened, it shows a significantly lower degree of friendliness. Adaptation to the touchscreen was not in vain - service information now eats up most of the usable space, leaving depressingly little space for the editable area. When you scroll the screen, Excel automatically hides only the title bar and formulas, as well as the bottom row with tabs, but once you start editing the content, they reappear on the screen. I did not find ways to reduce the size of service areas. Support for VBA macros is not implemented in the mobile version of Excel, so some documents that use macros cannot be edited. For my purposes, this is not the most significant, but tangible drawback.


In general, working with the mobile version of Excel is inconvenient both with and without a keyboard. Failed.

MS PowerPoint Mobile not worth a long comment. The application "with a stretch" is suitable only for viewing ready-made presentations. I didn't load the document with a complex presentation that included multimedia elements. It reproduced quite acceptable. However, an attempt to create a document on your own "from scratch" is a complete mockery of the user. Better not to try.

Microsoft Edge. In the browser, the keyboard is not so necessary, it’s just more convenient to click on the links on the touchscreen, but if there is a need, the keyboard somehow copes with the tasks. The same applies to other applications

Findings.
In general, my idea using a phablet as an under-tablet, as expected, showed not very satisfactory results. There is almost no hope that Microsoft will ever bring to mind both Win10 Mobile and its mobile application suite. Nevertheless, at least Word documents can be edited somehow. But the price for this is a multiple increase in size due to the size of the cover. Was the game worth the candle? Probably not.
It is likely that the functionality of the reviewed keyboard will be higher with a full-fledged tablet, but for the convenience of working with the desktop version of Windows, there is not enough touchpad. At the same time, the quality of performance leaves much to be desired, even if the performance as a whole did not cause any comments.
The resulting simulacrum in my case has unreasonably large dimensions, requires adaptation to a non-standard keyboard layout, the keyboard itself raises doubts about reliability and durability. A Bluetooth keyboard would cost more but take up less space. At the same time, the problems of working with applications would remain the same - these are already “built-in” disadvantages of mobile Windows, which, alas, are pointless to deal with.
Other disadvantages include the fact that the keyboard is, although not very powerful, but still a consumer of energy - it is powered from the Micro USB port. Of course, it would be more logical and practical the other way around - for the keyboard to be equipped with its own battery and serve as an additional "power bank" for the phablet. But for $7, it's pointless to expect such solutions.

For those who are looking for a keyboard for a small tablet, I think it is better to choose a bluetooth device with a touchpad. Let them be more expensive.

In the modern world, a tablet case is no longer just another accessory - it is a necessity for every conscious owner who wants to extend the life of his device. Undoubtedly, the production of touch devices is now on the rise, many manufacturers such as Asus, Huawei, Lenovo are improving the design of tablets in every possible way and making it more rigid. But, alas, not a single tablet is protected from accidental drops, bumps, scratches and scuffs.

Briefly about the main

While companies are increasing the production of cases for tablets, on the Internet on various forums and just in the comments under the product, whole battles of supporters and opponents of protective accessories are unfolding. Until now, none of the disputes has reached its logical end, the case for the tablet is an individual thing that is chosen based on their own beliefs and interests.

Few users decide to make an accessory with their own hands - this opens up incredible opportunities for them to fly a fantasy. Other owners of small 7 inch tablets prefer to carry them in their pants pocket, bag or jacket. But still, a larger percentage of users find extra money and buy protective cases for tablets. After all, the bulk of the tablets are large 10-inch tablets that you just can’t carry around with you: the weight eventually makes itself felt.

Overview of the most popular accessories

As a rule, everything is known in comparison, which allows you to identify the strengths and weaknesses of a particular accessory. To analyze their capabilities and features, for what exactly they were released, and so on. Previously, such an accessory was not given much importance: it does not matter if it exists or not, but the world does not stand still, but is constantly in motion and user requests are constantly changing. Therefore, covers for the tablet can be divided into several main groups:

  • tablet bag;
  • Case-pad;
  • Case for a tablet in the form of a book;
  • A complete accessory with a keyboard.

Cover-pad

This is probably one of the simplest yet most versatile pill accessories. Unfortunately, you can't do it yourself. After all, Asus, Samsung, Huawei, Apple devices have a complex external shape and it will not work to fit your own case under them.

The design of such an accessory is quite simple - it is worn on the back side of the device and protects the case itself from unwanted scratches or abrasions. This leaves the front panel unprotected, as shown in the image above. Such a tablet case does not provide the device with a high degree of security: a direct blow to a 7 or 10 inch screen and a trip to a service center is guaranteed.

Pad with frontal protection

A logical continuation of the above accessory was a very comfortable case with full protection from all sides. This model became very popular after the release of the first Nexus 7-inch jointly produced by Asus and Google.

Such a model has very good functionality, firstly, it completely covers the tablet from external influences, and secondly, a magnet is often inserted in the upper part - this allows you to use the tablet case as a stand in various configurations.

It is worth noting that some manufacturers have gone further and supply only the top cover in the form of a cover - it looks quite original and modern.

Making such a case with your own hands is quite difficult, so it’s easier to buy, and you definitely won’t regret your choice. Asus is constantly releasing new cases for the tablet, so choosing an interesting model for your 7 or 10 inch device will not be a big problem.

Accessory in the form of a book

This tablet case is very common among owners due to its simple design and ease of use. This accessory has a good degree of security, and the universal shape allows you to use it for both 7 and 10 inch tablets.

The tablet is attached using a fastener system:

  • rubber;
  • metal;
  • Special frame.

But the upper part of the cover can be fastened with a wide elastic band along the entire length of the cover or special rivets.

But, the main advantage of such accessories is the transformation into a very convenient stand, as you can see in the image above, for an Asus device. As you can see, the mount for the device itself is located around the entire perimeter of the case, which prevents the device from accidentally slipping out of it.

The top cover can be fastened both with special fasteners, and with the help of Velcro or a magnet. These tablet cases have won the love of millions of touch device owners around the world. Undoubtedly, it is possible to make such a stand with your own hands at home, but it will not be convenient for transportation.

The tablet bag is also not deprived of popularity, like the previously considered case. Such a model is an excellent solution for the safe transportation of tablets on weekdays. Plus, this case allows you to store various documents or small things in addition to the tablet.

This solution is perfect for devices from Asus, which is rapidly introducing 10-inch transformers into the lives of ordinary customers. It should be noted that transformers are the future of computer technologies: the simplicity and lightness of tablets, the power and versatility of laptops.

To date, there is a huge number of a wide variety of models on the market, so absolutely any owner will be able to choose a worthwhile option for themselves. A tablet bag is exactly what every modern user needs. Although such a case also has its drawbacks: the device is protected as long as it is directly in the bag.

Keyboard Accessory

While Asus is promoting the idea of ​​transformers, many users still prefer conventional tablets, because they are many times cheaper. Without thinking twice, manufacturers began to produce separate, miniature keyboards for 7 or 10 inch and combined them with protective accessories.

Convenient, practical, and most importantly, not as expensive as Asus transformers for the average buyer. The keyboard cover for the tablet can replace the owner on the road - a full-fledged laptop. Plus, the gadget has additional features:

  • Touch screen;
  • Mobile 3G Internet;
  • Dimensions and, of course, a small weight.

Those who have already managed to buy an Asus device are offered the above presented tablet case - it looks, of course, ridiculous, but it completely protects it from any physical influences. Trying to do something similar with your own hands, most likely will not work - a complex design will make itself felt.

Multifunctional cases

Recently, the concept of a tablet case has acquired completely different meanings and absolutely any thing that can not only protect a 7 or 10 inch gadget, but also extend or expand its operation, acts as its role.

Accessory with battery

Undoubtedly, a very interesting copy, which is produced by HP for its ElitePad 900 10-inch tablet. Such a tablet case compensates for the lack of HDMI and USB connector, and also allows you to install an additional battery with your own hands.

The operating time is plus 20 hours to the already available stock on the tablet itself. The accessory also provides convenient access to the micro SD slot and good sound in various operating modes. Such covers for the tablet are produced individually and in extremely limited quantities.

A much more interesting instance is a case with installed solar panels that are capable of accumulating a charge and giving it to the device. A great option for long hikes or walks, and additional compartments allow you to take with you the necessary trifle.

As you can see, manufacturers of protective accessories amaze with their imagination, because every year a huge number of various models for 7, 8 and 10 inch devices are released on the world market.

Be very careful when using this type of accessories, because cases require additional conditions for maintenance and use - read the instructions.

Modern society does not stand still, but is constantly on the move, so the previously discussed tablet covers are suitable for people who lead a calm rhythm of life. But what about extreme people, tourists or just people who lead an active lifestyle?

A very convenient and practical solution, many backpacks are equipped with an abundance of pockets by default, but only a few of them are adapted to securely store pills. The interior finish has a pleasant structure that is not able to harm the touch device. The main disadvantage of this solution is that you have to constantly get the tablet out of the backpack.

This backpack model is ideal for tourists who are away from civilization for a long time, but at the same time do not limit themselves in access to touch devices. Competent internal tailoring allows you to conveniently place devices throughout the volume of the backpack. Two USB cables for charging small equipment: a player, a smartphone and one for recharging a tablet. Making such a backpack with your own hands is quite possible, but chaos is guaranteed to you.

futuristic idea

Fans of Apple products do not surprise with their imagination, at the moment they are raising funds for the release of a kangaroo backpack. This tablet bag is worn on the front and allows you to interact with the tablet on the go.

The gadget is fixed on a special design, which eliminates the possibility of accidental loss or even theft. Now a long wait in line or a trip on public transport can be smoothed out by working on a tablet. Moreover, the developer endowed the bag with five modes at once:

  • Camera mode;
  • Game;
  • Walking;
  • Video mode;
  • Tablet mode.

It looks, of course, a little wild and unusual, but if everything works out, perhaps the bags will become incredibly popular all over the world. Moreover, turning the bag on its back - it becomes a regular backpack for everyday use.

Accessory at home

If many hours of searching did not give the expected results, then the only right decision is to make a cover with your own hands. In principle, if you do not pretend to be some kind of functional accessory, but want to make an ordinary protective case, then this can be done at home.

Preparation of tools

To make a cover, we need:

  • Waste carton box;
  • Glue ordinary and aerosol;
  • Standard sewing kit threads, needles, scissors;
  • Fabric with your favorite ornament;
  • Elastic.

blank

We cut blanks for the cover from the cardboard box, that is, we put the device and trace it along the contour, which correspond to the length and width of the tablet, as well as the thickness, as shown in the image above.

Fabric preparation

Now we put the blanks on the fabric and draw the dimensions along the contour, make a small indent for the future seam. We cut off two such pieces of fabric, iron them and proceed to the direct sewing of the accessory.

Case manufacturing

We sew the fabric blank around the perimeter, only leaving one side not sewn up - this is necessary in order to insert cardboard there. Turn the fabric right side out.

We sew the product

Now we spray the cardboard with aerosol glue and put it into an open hole, a smaller piece of cardboard can be thrown away - it is not needed. We smooth the fabric around the entire perimeter so that it turns out smooth and without wrinkles.

Almost ready

We tuck the fabric near the non-hemmed side and glue it to the cardboard base. We also glue a tie from the same fabric so that you can easily connect both covers to each other and ensure the safety of the device.

It remains only to glue the mounts for the tablet itself: first we put the device approximately in the center, mark out where the rubber bands should supposedly be placed.

Tablet mounts

Please note: they should be tight enough to securely hold the device, but at the same time not create difficulties when removing it. We glue it, and now to hide it, you can cut another small piece of fabric and stick it on the inside of the accessory.

As a result, we get a very simple, but original and interesting do-it-yourself case. The most eminent manufacturers can envy such design. In the choice of fabric, design and other things - no one limits you, imagination and a little free time - work wonders. Asus, with its branded accessories, can stand aside and breathe nervously.

Small master class

Hello, dear habrazhitel!

A month ago, succumbing to the persuasion of the built-in Wishlist, I unexpectedly lost my tablet. Bearing in mind that typing on tablets, as a rule, is not very convenient, I decided to order a Chinese overseas curiosity on Tinidil: a case-stand with a built-in USB keyboard.
It is about this curiosity that I want to tell you in this, if I may say so, review.

As it turned out, there are a great many such covers and they differ, in fact, in their size and type of USB connector. As part of this review, we will consider a case for seven-inch devices, with micro USB
connector.

The gadget itself with an already connected tablet looks like this:

Characteristics:
dimensions: 22.5 x 14 x 2.8 cm (of which 20 x 7.5 cm - pure keyboard)
weight: 300 g (together with the tablet - 640 g)
material: magic Chinese leatherette
price: $12
Appearance
When folded, the case looks like a book with a hidden magnetic clasp:


The entire skin is slightly corrugated, so all sorts of small dust particles are clogged there, which are subsequently not so easy to dig out. In addition, there is some smell - a kind of magical mixture of Chinese leatherette + glue + fig knows what else. But if you do not specifically sniff, then almost imperceptibly. Didn't taste it, sorry.
Interior
With an elegant movement of the hand, the case opens and turns into a stand with a keyboard (a la “laptop”). The magnetic fastener strives to return to its original state and therefore it will have to be cleverly hidden so as not to interfere.


By the way, using the cover as a book will not work, because, firstly, the tablet begins to slip under its own weight, and secondly, there is nowhere to put the keyboard.

Tablet mounts are located on the inside of the stand.


The two lower mounts are rigidly fixed, and the upper one, spring-loaded, can move to the very edge, thereby providing the ability to hold devices from 11 to 13 cm in width. The height (or depth?) of these mounts is 11 mm.

On the reverse side, the stand has a leg that provides some stability to the structure at an angle of 120 °. The angle of inclination is fixed, but this is not a problem: I did not feel any discomfort in this situation.


The leg is almost perpendicular to the surface of the table, which is why the whole structure can collapse if you suddenly decide to move it away from you. When folded, the leg is held by a magnetic latch.

There are two small through "pockets" between the stand and the keyboard. One is for fixing the USB cable, and the second is for the stylus. The stylus is included, but it is only suitable for devices with a resistive screen, so in my case it can only be used to dig into the ear.

Keyboard
Well, now let's move on to the main part, for which all this was started - to the keyboard:

As you can see from the photo, the keyboard is compact, with laptop manners. I would even say very compact: its width is only 20cm. Of course, after a full-size keyboard, it seems quite small and typing at first is inconvenient, but, having got the hang of it, you can type quite tolerably, and sometimes even blindly. For "groping" the keys, there are special buttons on F and J, respectively.
(The photo shows that these keys even differ in color, but in real life it is almost not noticeable).

The key travel is small, but still noticeable.

Along the perimeter of the keyboard there is such a convex border, the purpose of which is not very clear to me, but it prevents me from pressing the spacebar normally, which is why it is often “swallowed”. Although, maybe this is a matter of habit, we'll see.

If you really get to the bottom of it, you will notice that the buttons are a little crooked, which, however, does not affect the typing at all. In my version, there are no Russian letters on the keyboard, so those who care about this should take care of buying special stickers, since there are now in bulk.

Tablet interaction
In order for the tablet to “see” the keyboard, it must support USB Host Mode (as far as I know, these are devices with Android 3.1 and higher). My tablet immediately became friends with the keyboard, but when I wanted to have two layouts (Russian and English), some difficulties began. It turned out that it was impossible to switch layouts on the fly (except for climbing deep through the settings each time). Having carefully googled this question, I downloaded the Russian Keyboard softinka from the market, having set it up, I began to switch layouts by alt + shift and rejoiced.

And there really was something to rejoice about: now, when the cursor fell into the input field, I did not have a virtual keyboard pop up, covering most of the screen, and it was an incomparable feeling!

I was also pleased with some keyboard shortcuts. For example, Alt + Tab shows a list of 8 recently launched applications, between which you can switch (Alt + Shift + Tab also works!). The Esc button works like Back. Some standard applications have shortcuts with a Win button (for example, Win+C = contacts, and Win+L = calendar) and are called from anywhere.

On a tip from the comments, it became known that Fn + and Fn + ↓ work like Page Up and Page Down, respectively.

If the tablet is "asleep", then pressing any button will "wake it up", but you still have to unlock it through the touchscreen.

Conclusion
In general, for the money ($12), the accessory turned out to be quite good, even despite some of its shortcomings.
Afterword
Perhaps I missed some nuances that you would be curious to know? Ask and I'll try to answer as best I can.

ASUS Transformer and Microsoft Surface are great devices that combine a tablet and a full-fledged laptop. On the road, such a thing does not take up much space and is great for both work and leisure. He took out a thin keyboard from the bag, and you have a laptop in your hands, put it back - a tablet. Conveniently. But is it possible to do something similar from a regular Android tablet? Easily!

What for?

Even the cheapest modern tablets have extremely powerful hardware, the performance of which is enough to compete with netbooks. However, the tablet has a completely different purpose, which poses an obvious problem for us: what to take with us on the road? Is a tablet or netbook convenient for reading books, surfing the web and playing games - a great tool for communication and work? Carrying both with you is not the most fun, but we can go the other way.

Let's start with the fact that almost any tablet running Android supports the connection of a keyboard and mouse - in fact, this turns it into a kind of monoblock computer that you can lean against something, place the keyboard and mouse in front of you and work quietly. On the road, this is not very convenient, and even too much even for a geek, so smart Chinese have come up with special covers with a built-in keyboard that turn the tablet into an interesting device similar to a netbook with a flick of the wrist. Buying such a cover is definitely worth it, especially since it will cost no more than 20 US rubles, and the keyboard there is really good.

The second is the OS. It would seem that Android is not at all designed to work and you cannot do without a full-fledged netbook / laptop. But even here everything is in order, browsers easily serve several tabs, there are many keyboard shortcuts, a full set of UNIX utilities, a bunch of administration software, compilers, utilities, web servers and everything you can think of, except for absolutely professional software such as Photoshop or ProTools. But I doubt that anyone will be doing graphic art or mixing composition, sitting in the passenger seat of a car moving along the "magnificent" Russian roads.

In other words, the tablet has everything to use it as a workstation, but we'll talk about how to use this "everything" to its fullest.

Basic minimum

So, we have an Android 4 tablet, a keyboard, a mouse (optional) and the desire to turn it all into a workhorse.

I’ll make a reservation right away that a USB keyboard and mouse can only be plugged into a tablet that supports USB host (OTG) mode, so if this option is not in the tablet, you will have to use more expensive Bluetooth accessories, and if there is no Bluetooth support, then nothing you can do it - such a tablet is not good.

If the USB host mode is supported, the keyboard or mouse should be connected using the OTG cable that usually comes with the tablet and is a miniUSB male cable on one side and a full-sized USB female on the other (if the tablet has full-size USB ports, you can weave directly into them). If it was not included in the kit, an OTG cable can be bought at any mobile equipment store or ordered in China for one dollar (it is no worse). I want to warn you that usually not all ports support host mode, so you need to stick it in the correct one (usually it is signed by Host or OTG).

When everything is on hand, we hook the mouse and keyboard to the tablet - and voila, everything works. One could say that this would be enough, but Android can offer much more advanced keyboard control options. One of the main ones is a fairly developed and convenient system of keyboard shortcuts, which has existed since the first versions of the OS. So, to navigate the desktop and various menus, you can use the "arrows", and the key replaces the "Back" button, and - "Home" button. In addition to them, there is a whole set of other control combinations, including shortcuts for launching applications:

Android keyboard shortcuts

- analogue of the "Back" button - analogue of the "Home" button - analogue of the "Menu" button - switching between applications - switch layout - open settings - management of installed applications - change wallpaper - write a letter - music player - calculator - write SMS - calendar - contacts - browser - google maps - Search

A special place among them is occupied by the combination , which opens a search window, which in Android is similar to the search window of OS X or Ubuntu, that is, it allows you to search not only on the Internet, but also among installed applications, contacts and browser bookmarks. A very handy keyboard control tool.

Keyboard shortcuts are also available in applications, but only a small part of developers implement such control. Even among browsers where this functionality is a must, I could only find two that can be fully controlled using the keyboard. This is a standard browser and Google Chrome, which support the following set of combinations:

Browser combinations

Unfortunately, in Android there is no way to change the keyboard shortcuts or add your own, but the available ones will be quite enough to work with the tablet without any mouse, only occasionally touching the screen - select some hard-to-reach interface element.


Since we are talking about the browser, we need to take care of connecting to the Internet. Not all tablets are equipped with a 3G module, so you will most likely have to take the Internet in other ways. Two standard solutions are a 3G modem or Internet from a phone. The first option is more preferable, but on tablets with one host port (like mine), it will not allow you to also plug in a keyboard. The option of distributing the Internet from your phone via Wi-Fi is very convenient, but it consumes the smart battery at an incredible speed, so it is much better to use more economical Bluetooth for this purpose.

The situation with blue tooth in Android is rather strange, and its support varies greatly from version to version. Nevertheless, the distribution of the Internet via Bluetooth (PAN profile) has been supported for a long time, and, most likely, it is already in the smartphone (you should look for it somewhere in the area “Wireless networks -> Advanced -> Modem mode”). To connect to such a “translator”, Google recommends that you select the desired Bluetooth device from the list in the “Profiles” section and check the box “Use to access the Internet”. But in practice, such an item often simply does not exist, so you will have to use an independent implementation of the PAN profile, for example, “Bluetooth PAN” from the market, to connect. It requires root, but using it is as easy as shelling pears: launched, clicked on a huge round button in the middle of the screen.

In order to have access to all the necessary data on the road, you can transfer them to a USB flash drive in advance or use cloud drives like Dropbox or Google Drive. Both approaches are inconvenient because they do not allow automatic synchronization. But the Dropsync app can do it and does it very well. In fact, Dropsync performs the same task as the desktop version of Dropbox: it allows you to store files on a flash drive, periodically synchronizing them with cloud storage. Importantly, directories for synchronization can be selected individually, sending and receiving from the cloud only what is really needed on the tablet, such as books, music, source texts.

Using Dropsync is quite simple, you just need to select the directory to sync, the directory in Dropbox and choose the sync method: one way or both. After that, the software will hang in the background and will periodically perform synchronization. I immediately recommend buying the Pro version, it implements support for the Linux inotify technology for instant synchronization immediately after changing files, and also removes the limit on the file size of 5 MB and on one synchronized directory.

Virtual keyboard for Android tablets

You can work effectively in a terminal emulator without a hard keyboard. To do this, you just need to install the Hacker’s keyboard, which has keys , , navigation arrows, a separate line with numbers, and a separate panel with keys .

advanced option

Let's talk about more advanced use of the tablet. For a geek, and even more so for a person who administers remote servers, standard functionality and ordinary applications will, of course, not be enough to feel complete. Therefore, we need to get a Linuxoid gentleman's set, namely a terminal emulator, a set of command line utilities, as well as various SSH clients and rsync's. All this for Android is full, thanks to the Linux kernel.

First things first, we get root on the tablet. We have already described how to do this, especially since each device has its own methodology, which includes many nuances. So Google is here to help. Next, install the Android Terminal Emulator from the market, this is a standard VT102 emulator with support for everything you need. It supports all control sequences, which means all key combinations that you will type on the keyboard.


The standard Android installation includes a limited set of command line utilities (not even the cp command), but it's easy to expand it to the full by simply installing BusyBox using one of the many installers available on the market. After that, you can get a normal bash instead of the wretched sh that comes with the kit. To do this, install the GNU bash 4.2 Installer, run it and click the "Install" button. In order for the terminal emulator to know that we want to immediately get into bash at startup, go to the terminal settings and in the "Command shell" option specify the path "/system/xbin/bash -".


From now on, we have a full-fledged command line, but no SSH client and a good text editor. You can solve this problem by installing the good old ConnectBot and Vim Touch. As stand-alone tools, they do a great job, but they can't be used productively with a keyboard and if you need to edit various files directly from the terminal. Therefore, we will install native versions of these programs. Console Vim for Android can be obtained from this link. It should be unpacked, transferred to the tablet's memory card, and then put in the / system / xbin directory. Here's how to do it right in Android:


Installing console vim

$ su # cp /sdcard/path-to-binary /system/xbin # chmod +x /system/bin/vim

The SSH client, in turn, is in the SSHDroid application. All you have to do is install SSHDroid and copy the SSH client to the /system/xbin directory:

Installing ssh

$ su # cp /data/data/berserker.android.apps.sshdroid/dropbear/ssh /system/xbin # chmod +x /system/xbin/ssh

You can go even further and install an entire Linux distribution that has everything you want. It is especially convenient to use the Arch Linux Installer for this, which installs a minimal Arch Linux into the image without any unnecessary X's and other rubbish. And thanks to the archaic philosophy of rolling releases, you will always have the latest software, without having to install a new version of the distribution. The installer itself is incredibly simple, so I will not describe its use.

It is clear that during remote work we will most likely have to access the Web via a VPN, since open Wi-Fi in various cafeterias and hotels simply does not inspire confidence by definition. The new Android now has VPN support right out of the box, so setting up proxying will not cause any problems. Just go to the settings "Wireless networks -> More ...", click VPN, Android prompts you to set a PIN or password, this will have to be done, because otherwise they will not let us go further. Next, click "Add VPN profile" and specify the type of VPN (standard PPTP, L2TP / IPSec, IPSec Xauth or IPSec Hybrid), drive in the profile name, server address and keys, if necessary (for PPTP, of course, not necessary). We save, tap on the profile name, drive in the login and password, and all traffic starts to go through the tunnel.


If you're thinking about coding on the go, Google Play has tons of tools for that. To create small utility utilities and scripts, you can use the SL4A environment (code.google.com/p/android-scripting), which allows you to execute scripts written in sh, Python, Ruby, Perl, Lua, and other languages. The environment is equipped with an editor and a simple API that allows you to access the main functions of the tablet.

For more serious development, you can use the QPython environment, which, in addition to the SL4A API, offers access to the native Android API, as well as the Kivy cross-platform graphics widget library. Applications created with QPython will almost not be visually different from native ones. The Ruboto IRB environment generally offers full access to the Android Java API, but for the Ruby language.

I would especially like to note the AIDE environment, which allows you to create full-fledged Java applications for Android in Android itself. The environment is very advanced, with a full set of all the necessary features, including syntax highlighting, autocompletion, online hints, compiling and one-click launch. AIDE is fully compatible with Android SDK projects, so it can really be used for serious development. Particularly hardcore comrades can install the GNU GCC C / C ++ Compiler, the same GCC and a set of binutils that allow you to build software in the console.

HDMI

Carrying a tablet with you, and even having a keyboard and mouse connected to it, you will probably want to hook it up to the HDMI port of your TV or AV receiver. In principle, everything here is simple and boring to the point: plug in the cable and get a picture on the big screen. But there are some interesting points that I would like to talk about.


Screen blanking. One of the more frustrating things about Android's implementation of HDMI support is the need to keep the screen on. As soon as you press the tablet's off button, the HDMI is de-energized and the "big picture" disappears. You can’t disable this behavior using Android itself, but you can use the excellent Screen Standby program, which forcibly turns off the backlight of the screen, so you can safely watch videos, play games or surf the Internet without being distracted by a copy of the image on the tablet.

Screen Standby has many very useful settings, for example, turns off the backlight on its own when you plug in an HDMI cable. To do this, just enable the "Auto HDMI / MHL Detection" option in the "HDMI Detection" section (there are also settings for disabling when the application is launched or placed in the dock). Another very interesting feature is the transfer of the tablet to touchpad mode, when a cursor appears on the monitor screen, and the tablet screen turns into a large touchpad. It is included in the menu "Settings -> Touchpad setting -> Use touchpad function", but this function did not work for me, which is predictable, given the limited support for models.

Joystick and control panel. A tablet connected to a monitor or TV can be controlled not only with a keyboard and mouse, but also using a smartphone on the same Android. It is not necessary for this to go to the tablet via SSH or other means. You can use the virtual joystick BT Controller from the market. This program allows you to turn your smartphone into a virtual blue-toothed joystick, remote control or even a keyboard - there is already something for anyone.

BT Controller should be installed on both devices that are already connected via Bluetooth. Next, on one of the devices, press the “Connect” button, after which a message will appear on the screen asking you to select the device function: Controller or Host. We click on the Host tablet, after which an information plate appears in the upper right corner, symbolizing the successful connection and performance of the components. Tapping on the line “KB Enabled” on the plate will take us to the input methods settings menu, in which you should select BTController, and tapping on “KB Active” will allow you to switch to the BT Controller instead of the standard keyboard.

When all these operations are completed, you can use the joystick that appears on the screen. In the free version of the application, only one interface option is the SNES joystick, which is quite convenient to play games with, but it is not suitable for other purposes. The paid version of BT Controller allows you to choose between over thirty different joysticks, remotes and keyboards and, more importantly, create a new remote yourself using a special editor.


findings

An Android tablet can really be turned into a full-fledged desktop that is a pleasure to use. Of course, it will not replace a real laptop on Linux, but you will not notice any special problems in use either.
