Workmanager doesnt send coordinates to my server when phone is in sleepmode. Asynctask get killed?
I use the Workmanager (PeriodicWorkRequest) to get the coordinates every 15 min. To get the coordinates i use FusedLocationClient. That works fine.... but i also want to send them to my server.
If i start sending in 'public void onComplete' (see code) i have to use an AsyncTask (Other solution??). It works, when my phone is not in sleep mode. The intention is that the sending keeps running. How can I solve this (newby, examples makes me happy :))
MainActivity Start Workmanager
public static void scheduleWork(String tag) {
PeriodicWorkRequest.Builder SendLocation =
new PeriodicWorkRequest.Builder(LocationWorker.class, 15,
TimeUnit.MINUTES);
PeriodicWorkRequest locationCheckWork = SendLocation.build();
WorkManager instance = WorkManager.getInstance();
instance.enqueueUniquePeriodicWork(tag, ExistingPeriodicWorkPolicy.KEEP , locationCheckWork);
}
LocationWorker
@NonNull
@Override
public Result doWork() {
Log.d(TAG, "onStartJob: STARTING JOB..");
mFusedLocationClient = LocationServices.getFusedLocationProviderClient(mContext);
mLocationCallback = new LocationCallback() {
@Override
public void onLocationResult(LocationResult locationResult) {
super.onLocationResult(locationResult);
}
};
LocationRequest mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(UPDATE_INTERVAL_IN_MILLISECONDS);
mLocationRequest.setFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
try {
mFusedLocationClient
.getLastLocation()
.addOnCompleteListener(new OnCompleteListener<Location>() {
@Override
public void onComplete(@NonNull Task<Location> task) {
if (task.isSuccessful() && task.getResult() != null) {
mLocation = task.getResult();
Log.d(TAG, "Location : " + mLocation);
double latitude = mLocation.getLatitude();
double longitude = mLocation.getLongitude();
// SEND TO SERVER
AsyncTask.execute(new Runnable()

}
Log.i(TAG, "responseBody: "+responseBody);
//return connection.getResponseCode();
} catch (IOException e) {
e.printStackTrace();
}
}
});
mFusedLocationClient.removeLocationUpdates(mLocationCallback);
} else {
Log.w(TAG, "Failed to get location.");
}
}
});
} catch (SecurityException unlikely) {
Log.e(TAG, "Lost location permission." + unlikely);

try {
mFusedLocationClient.requestLocationUpdates(mLocationRequest, null);
