The AVD emulator on Android Studio display shows all characters at 1:1 resolution grainy. It is difficult to read the text of the app under testing. To overcome this problem:
- Create the AVD emulator device and set to no borders or skin.
- Instead of a docked view, select the Window view, so the device opens in it’s own window.
I had selected a Pixel 3 when creating the AVD and the above approach fixed the resolution.
Another alternative is to use a Physical Device for testing or debugging apps.
