Meet some mandatory requirements for migrating to Android 12

1. Replace foreground services with Workers
2. Support approximate location
3. Fallback to inexact alarms if the SCHEDULE_EXACT_ALARM permission is revoked
4. Specify the mutability of each PendingIntent
5. Explicitly declare the android:exported attribute for app components that use intent filters
