Foreground Service Not Receiving Location Updates In Android 7.0+ When Screen Is Off

I am trying to create an Android application that continuously logs device location data in realtime while the device screen is off. My code works correctly with Android 6.0 and ea

Solution 1:

I've spent the past week trying to get Location Services in Foreground. Finally got it working by including this in the manifest.

android:foregroundServiceType="location"

I hope this can help someone in the future!

Solution 2:

I had the same issue and I have found a working solution. In order to listen to location updates, you should NOT call this method:

public Task<Void> requestLocationUpdates(LocationRequest request, 
LocationCallback callback, Looper looper)

You should use a pending intent instead of a callback, i.e. you should call the method:

public Task<Void> requestLocationUpdates(LocationRequest request, 
PendingIntent callbackIntent)

Solution 3:

LocationServices.FusedLocationApi is deprecated.

I just refactored my App as follows. Hope it helps:

This is what I am calling in the onCreate-Method of my Service:

publicvoidstart(Context ctx) {
        FusedLocationProviderClientclient= LocationServices
                .getFusedLocationProviderClient(ctx);
        //Define quality of service:LocationRequestrequest= LocationRequest.create();
        request.setInterval(1000); //Every second
        request.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        if (locCallback != null) {
            client.removeLocationUpdates(locCallback);
        }
        locCallback = createNewLocationCallback();
        client.requestLocationUpdates(request, locCallback, null);
}

And this is the method for creating the Callback:

private LocationCallback createNewLocationCallback() {
    LocationCallbacklocationCallback=newLocationCallback() {
        @OverridepublicvoidonLocationResult(LocationResult result) {
            Locationloc= result.getLastLocation();
            // Do something with the location (may be null!)
        }
    };
    return locationCallback;
}

Guess, I also found that somewhere as example, but did not keep the reference.

I do not have Oreo on my own. But some testers confirmed, that it works.

To keep the service in foreground, I am just calling "startForeground" afterwards in the onCreate method of my service.

Solution 4:

I had been experiencing this issue on emulated devices running 7.0 and 8.0 and consistently the location callback was not being triggered when the screen was off (cmd+P). I was finally able to get my hands on a real 7.0 device (Galaxy S7) and I was not able to replicate the issue. Sorry if I wasted anyone's time, apparently it is an emulator issue.

Solution 5:

one solution might be this :

check if location is not received in 2 minutes stop/start whole start location update again . although foreground service must have solve the problem
