### Working with Android Auto

To test [notification extension to Android Auto](https://developer.android.com/training/cars/communication/notification-messaging), Developer settings and Unknown sources need to be enabled in
the Android Auto settings:

1. Open the Settings app on your device
2. Search for Android Auto, or click on Connected Devices > Android Auto
3. Scroll all the way down to Version, and click it 10 times to enable Developer settings
