I am using SDK Manager 3.34 and downloaded SDK 28 and google_apis_playstore/x86_64.
I created a 6" AVD and then "Start"ed it.
The colored circles move around the screen, then a colorful "G" appears with a animated progress bar under the G and then.......nothing - it just keeps animating the progress bar and never fully boots up.
I tried the power off/home - still NG.
I tried deleting and recreating the AVD, still same.
This is a common problem with Android emulator. I don't have any good suggestion other than to try different settings and try to recreate the emulators. Make sure that they are actually deleted from the B4AEmulator folder.
