Android emulator shows nothing but blank screen

Question

I am a complete nOOb to Android programming and trying my hands at it for the first time by going through the tutorials. The problem is that I have created multiple emulator

Answer 1

I had the Problem with black screen plus audio fail messages with a newly installed Android Studio 3.4.1 on a fairly new amd machine. so i installed arm based virtual devices, used the Nexus 4 API 15 on targed 4.0.3 (Google API) as recommended for a first start.

I changed windows settings -> privacy -> microphone-> let other apps use it to fix the failing audio messages.

for the black screen all the above suggestions didnt work for me, until i changed the settings on extended controls once the black screened virtual device comes up:

went to settings -> advanced and changed both "OpenGL ES renderer" and "OpenGL ES API level" to "Desktop native OpenGL" and "Compatibility" respectively.

a word of caution, the devices seem to be very fragile and get corrupted when changing stuff back and forth in avd manager, especially when changing system image.
