How to turn on emulator screen?
In Android Studio 4.0 for Mac:
- Tools >
- AVD Manager >
- [Edit your current device] >
- Show Advanced Settings >
- Emulated Performance >
- Boot Option: Cold Boot.
A rude way to refresh an emulator is Tools > Android > AVD Manager, then find your emulator and at right side click gray arrow, then select "Wipe Data".
This issue can be solved by starting emulator with cold boot. As @CoolMind said Tools > AVD Manager, in actions tab push down arrow and select cold boot now.
I am using IntelliJ IDEA, but basically it is the same with Android Studio. Firstly, open Tools > Android > AVD Manager, in the Actions column, click the arrow button then choose:
- Cold Boot Now
Try a cold boot first.
- Wipe Data
In case cold boot cannot solve the problem or it occurs again when you start the emulator next time, you should wipe data.
