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:

  1. Cold Boot Now

Try a cold boot first.

  1. 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.
