I am using IntentService before to make my ActivityRecognition work in the background for location updates but since Android 9+ IntentService deprecated and it's no longer working in recent Android versions. So I tried to use WorkManager but I am a bit confused about how I can migrate from IntentService to WorkManager because WorkManager doesn't have any return method like service.
Start Of IntentService Like this (ActivityRecognition)
Intent ActivityRec_intent = new Intent(this, Activity_Recognized_Service.class);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, ActivityRec_intent, PendingIntent.FLAG_UPDATE_CURRENT);
activityRecognitionClient.requestActivityUpdates(timeInLong,pendingIntent);
IntentService
public class Activity_Recognized_Service extends IntentService {
/**
* Creates an IntentService. Invoked by your subcl ass's constructor.
*
* @param name Used to name the worker thread, important only for debugging.
*/
public static final String TAG = "###RECOGNISED SRVCE###";
Timer timer;
LocationRequest mLocationRequest;

super("Activity_Recognized_Service");
}

super(name);
}

How can i make my code work for background task and make it run even when app is closed.
