Safer component exporting
If your app targets Android 12 or higher and contains activities, services, or broadcast receivers that use intent filters, you must explicitly declare the android:exported attribute for these app components.

Warning: If an activity, service, or broadcast receiver uses intent filters and doesn't have an explicitly-declared value for android:exported, your app can't be installed on a device that runs Android 12 or higher.
If the app component includes the LAUNCHER category, set android:exported to true. In most other cases, set android:exported to false.

The following code snippet shows an example of a service that contains an intent filter whose android:exported attribute is set to false:

Workaround:
* [BroadcastReceiver] --> [BroadcastReceiver(Exported = true)]
* [Service]           --> [Service(Exported = true)]
