How to Restart an Android Emulator

22 April 2024 Stephan Petzl Leave a comment Tech-Help

When working with Android emulators, you might encounter scenarios where you need to restart the emulator. This could be due to changes in configuration, application testing, or to resolve issues that require a reboot. Let’s explore several methods to restart an Android emulator effectively.

Restarting via Android Studio

Android Studio provides a straightforward way to restart your emulator:

  1. Open Android Studio.
  2. Navigate to Tools > Android > AVD Manager.
  3. Select your emulator device from the list.
  4. Click on “Cold boot now” to restart the emulator.

If you need to reset the emulator to its factory settings, click on “Wipe data” instead.

Restarting from the Command Line

To restart an emulator from the command line without loading the snapshot, you can use the following command:

emulator @avd_name -no-snapshot-load

This command initiates a clean boot, treating the emulator as a new device.

Using ADB to Reboot

If you have a single emulator running, you can also use the Android Debug Bridge (ADB) to reboot:

adb -e reboot

This command will cause the emulator to reboot. Make sure that you have only one emulator running, as the -e flag targets the currently running emulator.

Restarting from the Emulator UI

For Android versions prior to Android 12, you can simply tap and hold the Power button within the emulator, then select the Restart option from the menu that appears.

In Android 13, swipe down twice from the top of the screen to access the power off button, which includes a Restart option.

Rebooting an Emulator with Android Studio Bumblebee

If you’re using Android Studio Bumblebee, you can press and hold the power button at the top of the emulator window to bring up the device’s power menu, allowing you to select the Restart option.

Handling Power Button Gesture Changes

In newer versions of Android, the Power button gesture may be set to trigger Google Assistant by default. To revert this behavior:

  1. Open the emulator’s Settings app.
  2. Navigate to System > Gestures.
  3. Select the “Press and hold power button” option.
  4. Disable the gesture or configure it to show the power menu.
