Foreground/Background on Android
A good sample Demo for Android Local services is
GitHub\Object Pascal\Multi-Device Samples\Device Sensors and Services\Foreground Location Tracking
https://developer.android.com/about/versions/oreo/background-location-limits
In an effort to reduce power consumption, Android 8.0 (API level 26) limits how frequently an app can retrieve the user's current location while the app is running in the background. Under these conditions, apps can receive location updates only a few times each hour.
In Unbind
JavaService.startForeground(NotificationId, GetNotification);
Monitor Main Activity State Via HandleApplicationEvent
case ApplicationEvent of
TApplicationEvent.WillBecomeForeground:
TApplicationEvent.EnteredBackground:
https://developer.android.com/about/versions/10/features#fg-service-types
Implementation note
Android 10 requires the foreground service type to be declared in the AndroidManifest.xml file. For this reason, this demo application uses the AndroidManifest.template.xml file as a workaround for adding the foregroundServiceType attribute in the service declaration:
<service android:name="com.embarcadero.services.ForegroundLocationTrackingService"
android:exported="false"
android:foregroundServiceType="location" />
Implemented by replacing the <%services%> in the application template with the above text.
