  • Direct Boot

    Android 7.0 runs in a secure, Direct Boot mode when the device has been powered on but the user has not unlocked the device. By default, apps do not run during Direct Boot mode. If your app needs to take action during Direct Boot mode, you can register app components that should be run during this mode. more
