Apple M1 chip Android studio 2022.1.1 Patch 1
This is a known issue, please check related SO post.
You can try to use a newer version of Android Studio (from 2022.2), or the workaround mentioned in the above post:
Disable Code author option in Settings (MacOS: ⌘ + , Win/Linux: Ctrl + Alt +S) > Editor > Inlay Hints > Code Vision.
What is the shortcut to create a new line in Android Studio editor (like ctrl+enter in Visual Studio Code)?
I believe its Shift + Enter
If you want to change it ::
Go to File > Settings > Select Keymap > Select Editor Options > Start
a New Line
Shift + Enter

I was searching about R class in my project to get look on it without editing it.
When I press ctrl and click on R Android studio opens the resourse file instead of R class
Where does it exist in my project structure?
This is not about understanding R class in Android, It is about finding it the project for just having look inside it.
You can find R class by searching it with "shift + cmd + o" or "double shift".
I guess new android studio update directs to the xml source of the resource.
Please check in this path "app\build\intermediates\incremental-verifier\debug\your.package"
Can anyone give me some suggestion or link of all controls of Android Studio keyboard shortcuts?
Move to File -> Settings -> Keymap and change Keymaps settings to eclipse so that you can use the short cut keys like in eclipse.
Preferences > Keymap will show you all the keyboard bindings.
A couple helpful hints to help you find features:
You can search actions by name; on MacOS the keybinding is Command+Shift+A. You can start typing the name of a command and it will show you all matching commands and their key bindings if they have one. That's really convenient for looking up the key shortcut for something if you have a hint of what it's called.
In most dialogs/windows there's a search box, and you can usually just start typing to start a search. It's especially good for preferences, where there are so many options that are hard to find.
I may be late to answer this, but would like to help all others who come up to this page from now.
Here is the list of all the most productive shortcuts that I have been using regularly in my day to day Android development. It saves a lot of time, seriously.
Find only classes - CMD + o
Find files - CMD + Shift+ o
Find everything - Double Shift
Find symbol - CMD + Alt+ o
Find in page - CMD + f
Find usages - fn + Alt+ f7
Generate boilerplate code - CMD + j
Quick fix - Alt + Enter
Code completion - Ctrl + Space
Definition of a class or method - Alt + Space
Navigate to a class or method - CMD + Left Click
Refactor rename - fn + Shift+ f6
Run app - Ctrl + R
Format code - Alt + CMD+ L
Show documentation - fn + f1
Mode code up/down - Shift + CMD+ up/down
Generate Code - CMD + N
Recently opened files - CMD + e
Recently edited files - CMD + Shift+ e
Delete lines at one go - CMD + Delete

On the Mac OS go to Android Studio -> Preferences -> Keymap
to assign a keyboard shortcut, you need to navigate to
file --> setting --> keymap --> search and than right click and add keyboard shortcut --> in first stroke
you can add/change like
ex:
you want to assign Cntl + w than use Cntl with w
Android Studio > Preferences > Keymap > Select Your Option.
Default is: IntelliJ IDEA Classic
After Android Studio updating, you sometimes need to do that. For example, I updated Android Studio 4.2.1 and I did this because it turned automatically default Keymap which is IntelliJ IDEA Classic. I prefer to use MacOS.
Go to Help and select Default Keymap Reference will point you to one of these default keyboard shortcuts for Android Studio. It has all the keyboard shortcuts you can do in Android Studio. It's says for it's IntelliJIDEA but Android Studio is based off IntelliJIDEA, so all the keyboard shortcuts listed there apply in Android Studio.
Windows and Linux
Mac
Here is the official list of the shortcuts of Android Studio for Windows, Linux and Mac:
https://developer.android.com/studio/intro/keyboard-shortcuts.html#configure_custom_keymaps
if you have a favourite plugin that doesn't have a shortcut, just navigate to
Settings > KeyMap > Double click Plugins > Select desired plugin > Add
Keyboard Shortcut :: Then press down the hot keys you want to assign for the
plugin and click OK.
PS. be careful not to override any important AS shortcut.
I just switched from Eclipse to Android Studio (IntelliJ).
I can't figure out how the autocompletion works! I tried Control + Space, Control + Shift + Space but i have no relevant suggestion. Not in the Java files, not in the layout files.
Is there another shortcut? Do I need to enable some option beforehand?
Preferences > Keymap > Code > Completion > Basic/SmartType:
It was actually a display problem. I'm using two screens, and the suggestions only appear when the IDE is on the main one.
The (imperfect) solution is to define the display where I'm using the IDE as the main one.
Just remove all the folder "AndroidStudioPreview";
On Windows:
Go to your User Folder - on Windows 7/8 this would be:
[SYSDRIVE]:\Users\[your username] (ex. C:\Users\JohnDoe\)
In this folder there should be a folder called .AndroidStudioPreview
On Mac OS X
Remove these files:
~/Library/Application Support/AndroidStudioPreview
~/Library/Caches/AndroidStudioPreview
~/Library/Logs/AndroidStudioPreview
~/Library/Preferences/AndroidStudioPreview
You can get your Autocompletion suggestions back in Android Studio by doing: File>Invalidate Coches/Restart...>Invalidate and Restart
