Android Studio - Why emulator process killed when no skin chosen

I used Android Studio before and setup buildin device (Pixel 3), I remove "Enable device frame" option for saving screen size.
All works fine.
Today I tried to setup a device with a new screen resolution (iPhone 11 Pro like - 1125x2436). I delete old Pixel 3 and created a new device, remove "Enable device frame" option, start. After progress bar appear the end, the emulator is closed and error appear:
"The emulator process for AVD devicename was killed."
I trying some google, updated Studio, rebooted PC (Linux), created new devices, but nothing helped.
I tried chose "Enable device frame" option and pick a skin. After that emulator successfully started (!).
Can anybody explain why emulator not starting without skin? Can it be fixed somehow?

Just fixed the issue.
For some strange reasons emulator launch without device frames after I changed screen resolution from 1125x2436 to 1126x2436.

Android Emulator broken when rotating display

I am facing an issue with the Android emulator.
When the emulator boots up everything is fine, regardless the default display orientation.
When I press one of the buttons to change the display orientation, the emulator window rotates but, the content is completely messed up.
See the pic below.
The same happens with all the AVDs I have created and with different android images.
I've already reinstalled/updated the emulator from package manager.
Any idea about why this is happening?
The work environment is:
Mac OS Big Sur,
Android Studio v4.1.1
Android emulator v30.2.6
Thank you for your help.

This was a bug in the Google Android Emulator version 30.2.x.
It was fixed in version 30.3.5 (approximately 8 January 2021). Apply the update like this:
Stop or Force Quit all the running AVD emulators
Android Studio ➔ Tools ➔ SDK Manager ➔ SDK Tools (click this tab in the middle of the dialog) ➔ Android Emulator
The status should say "Update Available"
Click the Checkbox so that it will change from a horizontal line to a checkmark, and so that the download symbol appears on the left.
Click the Apply or OK button
It should download version 30.3.5 or higher, for "Android Emulator".
After the upgrade is applied, relaunch your emulators.

Try running the emulator inside Android Studio. Go to settings-tools-emulator and check the box there to run the emulator inside Android Studio. When you rotate it after it should rotate faster than in the AVD's standalone application, and not break the display. This should fix the broken display problem, without making a new AVD. Make sure you have updated to the most recent version of Android Studio first, v4.1.

The android emulator defaults to have auto rotate turned off. Turn on auto rotate the normal way you would on your phone and it will work.

Android Oreo black screen in Android Studio

I am using the 2.3.3 version of Android Studio in Windows 10. In AVD every virtual device is able to run all verisons of android except Oreo. After starting the emulator with Android 8.0( API level 26) the ram usage of emulator stops around 400-410MB and then nothing happens, just a mobile screen with black screen even without a loading animation. How can I fix this problem?

Step 1- Made a new emulator(Any).
Step 2- then fixed another problem the black screen by changing the settings to use hardware graphics.(Dunno if this problem was related to the bug)

Can't run my app on android studio

I have downloaded android studio and now i am trying to run an app.I haven't changed anything in code or design.I am using version 2.2.2
When i click on run it gives me an error
init: Could not find wglGetExtensionsStringARB!
But emulator opens.Then there is blank black screen for 2-3 minutes,then androidtitle for another 5 minutes.This is what i get.
But i don't know where is my app?

What you're running is Android version 7.1 (Nougat MR1). You can see the list of apps (app drawer) by clicking on the small ^ (caret) icon above the opaque area highlited as a red circle in the picture below

emulator opens.Then there is blank black screen for 2-3 minutes,then androidtitle for another 5 minutes.
This is normal. You should wait until the emulator fully boots and run your app again. If your development computer has an Intel processor, be sure to install HAXM. It will greatly increase the speed of the emulator.

Android emulator resolution, aliasing, gpu emulation

I just downloaded the Android 4.1 (API 16) packages using the SDK Manager and created an Emulator for JellyBean. What I see now is everything on the JellyBean emulator is aliasing. When I open the screen capture dialog in DDMS, the screen is HUGE - I think the emulator is scaling that down, thus causing the aliasing. Screenshot:
And here are the emulator settings:
I've used these same settings (minus the GPU emulation = yes) before for my ICS emulators, including the built-in screen resolution WXGA720. What settings should I change to get rid of this problem?

Make sure that Scale display to real size is unchecked in the Launch Options dialog (which appears after clicking on Start... in the AVD manager).
