All AVD images work on my machine except for Android 9.+ (Google Play) & Android 9.+ (Google APIs) (the Android Studio emulator for Android Q b
In my case all other emulators started, except Q. I have all needed SDK and AVDs.
But every time emulator didn't start without any error.
I saw Emulator in Android Studio doesn't start and found a way to understand a reason. I started from avd path:
D:\Android\emulator\emulator.exe -avd Pixel_2_API_29 -netspeed full -netdelay none
and got an error: PANIC: Broken AVD system path. Check your ANDROID_SDK_ROOT value [D:\Android]!. In PANIC: Broken AVD system path. Check your ANDROID_SDK_ROOT value I found that we should read config.ini inside 'Pixel_2_API_29.avd' folder and detect the line
image.sysdir.1=system-images\android-29\google_apis_playstore\x86\
I understood that I missed android-29 image in SDK path!
I knew that moved SDK and AVD folders from C:... to D:\Android, but SDK was kept in two folders.
And I forgot to change one system variable (ANDROID_HOME):
So I changed it to D:\Android and restarted the PC.
After restarting I deleted old SDK folder (in 'AppData\Local\Android'). Then I started again:
D:\Android\emulator\emulator.exe -avd Pixel_2_API_29 -netspeed full -netdelay none
