Not all users of phones and tablets on the Android operating system know that in addition to the main purpose of buttons, a mobile gadget also has the ability to use them in combination. These are some kind of "hotkeys" or "hot keys" with which you can perform some useful operations at once, without wasting time searching for them in the operating system menu. I want to tell you about the most common of them.

Taking a screenshot- just to find an option that will help you take a screenshot of your smartphone is not possible on every device. Some manufacturers add this capability to their user interface, and some don't. Fortunately, at least the developers from Google did not forget about it, having tied the ability to take a screenshot of the screen by pressing a key combination - at the same time the device's power button (Power) and the volume down button (Volume -).

As soon as you do this, Android will immediately take a snapshot of what is currently displayed on the screen. After that, the PNG file will be automatically saved in the Image Gallery, namely in the "Screenshots" folder.
Note: Some manufacturers are deviating from a single standard and reassigning keys. So, for example, you need to hold down the volume down and Home (Nome) buttons.

Recently used apps- on those models of smartphones, which have at the bottom not three, but only one button - "Home" (Home). In this case, it also has additional functionality, namely the ability to open a list of applications that you have recently used.

To open it, simply press and hold the touch key "Home" to display a list of used programs on the screen. If you need to clear the list, click the button at the bottom of the screen. At the bottom right, you can reset this list. And if you still click on the "Menu" on the left - and the Android Task Manager will open.

All owners of Android phones know that in order for their device to turn off, you need to hold the Power button for 5-10 seconds. And in order to simply reboot the device, you must first turn it off and then turn it on. Inconvenient? Certainly! But there is an easier way. Press the power key, hold for a couple of seconds and release. The following menu should appear:

Muting the sound during an incoming call can be done very quickly and easily! If you received a call at the wrong time, but you do not want to drop the call, then simply use the volume rocker of the device. It doesn't matter in which direction you push it - increase or decrease. The effect should be the same: the sound should be muted. By the way, on some models of smartphones the same effect can be achieved by placing the gadget on the table with the screen facing down. The subscriber's call will continue, but in silent mode.

P.S .: And I also want to note that sometimes some manufacturers in their proprietary graphical UI skins for Android make it possible to reassign the functions of some keys, which is also sometimes very, very convenient. Therefore, I advise you to study in detail the settings of the device!

Translation

Let's get straight to the point. You are not here to find out the story of my life. Let's start.

There are a number of keyboard shortcuts I've encountered when entering the corporate world. I divide them into two groups.

1. Search hotkeys

Don't remember where a certain word was used? Use these hotkeys to solve your problem.

i) Ctrl + Shift + F: When you use this combination, a search box opens where you can search for a word, class, or any other object. AS (Android Studio) will scan the entire project to see if it is in the project.

ii) Shift + Shift: Tired of using the navigation bar on the left? Then you can get to the desired file from this window, which opens by double-clicking on Shift. Just enter the beginning of the name or the full name of the desired file and AS in the window will list the search results. You can also open specific preference windows with this keyboard shortcut.

2. Navigation hotkeys

i) Ctrl + Click: Get to the markup file or Java file by clicking on it while holding down the Ctrl key.

ii) Alt + up / down: Feel free to navigate the class headers and their methods with this combination.

iii) Alt + Right / Left: Use the left / right arrows in conjunction with the Alt key to navigate through open project files such as a markup file or class file.

Active templates

i) "Toast" + Tab: Typing the word “Toast” and then pressing the Tab key will generate a finished Toast template.

There are many built-in templates to help you get started, such as
ii) loge + Tab
iii) logd + Tab
iv) logr + Tab

And many others. The beauty of this feature is that you can add your active templates to the settings. Just double Shift and go to the Live Templates section where you can add your own template.
And the most important and saving combination is

v) Ctrl + D

Which automatically completely duplicates the line on which the cursor is currently located.

That's all guys.

LAST:
Want to keep your code clean? Just use
Ctrl + Shift + L

And your code in the currently selected files will be properly formatted.

Here are 50 tricks, keyboard shortcuts, plugins, and useful links for Android Studio to help developers be more productive.

Visual

1. Color scheme in material colors for the console

To change the view of the console, go to Preferences (Settings on Windows and Linux) → Editor → Colors & Fonts → Android Logcat and change the color for each kind of console messages.

For example, colors as in the picture above:

• Assert # BA68C8
• Debug # 2196F3
• Error # F44336
• Info # 4CAF50
• Verbose #BBBBBB
• Warning # FF9800

2. Preventing the console from cleaning up when the application crashes

Go to the Android Monitor panel and select Edit filter configuration from the dropdown on the right.

3. Install the correct coding for Android Studio / IntelliJ IDE

Go to Preferences → Code Style → Java and in the Scheme drop-down list select the desired code style or install a new one.

Two styles worth mentioning in particular:

You can import a theme, as in the example:

4. Use split screen to improve productivity

To activate split screen, right click on the main screen taboo and select Split Vertically / Horizontally.

For maximum performance, you can set your own keyboard shortcuts for this action. Go to Preferences → Keymap and find Split Vertically. Open the context menu and select Add Keyboard Shortcut. For example, you can set the combination control + alt + v.

5. Distracted mode

Distraction will help you concentrate on your work. The editor will expand the work area with the code to full screen, hiding unnecessary interface elements. To activate the mode, open the View menu and select Enter Distraction Free Mode.

6. Using live templates

Use the combination cmd + j (ctrl + j for Windows / Linux).

There are many pre-built code templates that can be used, such as Toasts or if.

You can use your own live templates. How to do this is described in the resources for Android Studio and IntelliJ IDEA.

Hotkeys and useful commands

1. Best team - Search for command

It is called via the combination cmd + shift + a (for Windows and Linux: ctrl + shift + a). For example, you need to close the current tab, but you don't know how. Just write close and get a command or keyboard shortcut for that.

2. Search for recent actions in the copy / paste buffer

Called via cmd + shift + v (Windows and Linux: ctrl + shift + v). By default, the last 5 actions are available for copy / paste.

3. Activating the multicursor

Enabled via control + g (and alt + j for Windows and Linux).

4. Open a class

You can open a new class via cmd + o (Windows and Linux: ctrl + n)

5. Open file

A new file is opened with cmd + shift + o (Windows and Linux: ctrl + shift + n)

6. Search by symbol

Cmd + option + o (Windows and Linux: alt + shift + n)

7. Transition to implementation

For example, you have an interface. Click on the name of the interface, press cmd + option + b (Windows / Linux: ctrl + alt + b) and select Go to implementation - and you will be taken to the class that implements this interface.

8. Go to the ad

Using the combination cmd + b (Windows and Linux: ctrl + b), you can quickly go to the declaration of a class, method or variable.

9. Jump to type declaration

Let's say we have some code:

Java

Employee employee = new Employee (“Michal”);

Employee employee = new Employee (“Michal”);

With the cursor positioned on employee, using the combination control + shift + b (Windows and Linux: ctrl + shift + b), you can go to the place where the Employee class is declared.

10. Go to super

For example, you are overriding a method. If you position the cursor on the method name and choose to use the combination cmd + u (Windows and Linux: ctrl + u), you will be redirected to the parent method.

11. Switching between tabs

This is done through the combination cmd + shift + [(left arrow) or cmd + shift +] (right arrow) (Windows for Linux: instead of cmd - alt).

12. Switching between Design / Text tabs

For Android Studio, the combination control + shift + ← / → works in layout mode (Windows and Linux: alt + shift + ← / →).

13. Close the current tab

The shortcut cmd + w (for Windows and Linux: ctrl + F4).

14. Hide all windows

Via cmd + shift + F12 (Windows and Linux: ctrl + shift + F12).

15. Minimize the Android Studio instance

Combination cmd + shift + F12 (Windows and Linux: ctrl + shift + F12)

16. Format the code

Cmd + option + l (Windows and Linux: ctrl + alt + l).

17. Automatic indentation for lines

Through the combination of control + option + i (Windows and Linux: ctrl + alt + i).

18. Implementation of methods

By implementing an interface, through the combination control + i (Windows / Linux: ctrl + i), you can quickly import the methods provided by this interface.

19. Smart completion

It is turned on via the combination control + shift + space (Windows and Linux: ctrl + shift + space), the list is adjusted to the expected type.

20. Search

Сmd + f (Windows and Linux: ctrl + f).

21. Find and replace

Cmd + r (Windows and Linux: ctrl + r).

22. Moving lines from code to resources

When the cursor is on the text, use option + return (Windows / Linux: alt + enter).

23. Build and run the project

Will work through the combination of control + r (Windows and Linux: shift + F10).

Plugins for Android Studio and Intellij IDEA

1. Key promoter - will help you to use the keyboard more often instead of the mouse.
2. String Manipulation - allows you to change the appearance of the text on the fly (for example, change names in CamelCase or set uppercase characters).
3. Android Material Design Icon Generator - helps with adding material icons to the project (by default it reacts to cmd + shift + m).
4. ButterKnifeZelezny - helps to find the corresponding views in the layout by reference.
5. IntelliJ / Android Studio Plugin for Android Parcelable boilerplate code generation - generates Parcelable implementation based on class fields.
