When launching waydroid with GAPPS for the first time you will be notified that the device is not certified for Google Play Protect. You can follow the instructions on screen to self certify your device, or here's a shortcut:
- Open a Terminal
- Run the following command:
sudo waydroid shell -- sh -c "sqlite3 /data/data/*/*/gservices.db 'select value from main where name = \"android_id\";'"- Use the string of numbers printed by the command to register the device on your Google Account at https://www.google.com/android/uncertified
- Give the Google services some minutes to reflect the change, then restart waydroid with:
waydroid session stop
