Android [LocationManager] requestLocationUpdates(), java.lang.RuntimeException

Question

I am getting this error when requestion for location updates inside service . Location permission is granted, LocationManager is not null, Provider is not null.

LocationManager: [LocationManager] requestLocationUpdates(), 
    java.lang.RuntimeException

Location code that I am calling inside onStartCommand() :

@SuppressLint("MissingPermission")
    private void createAndRequestLocationUpdates() {
        try {

            if (!TrackThatUtils.isLocationEnabled(getApplicationContext())) {
                Log.e(TAG, "Location is disable.");
                return;
            }

            if (locationManager == null) {
                locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);

                addProximityAlert();
            }

            if (locationManager == null || !locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
                Log.e(TAG, "Location provider is disable.");
                return;
            }

            // getting GPS status
            boolean isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);

            Log.e(TAG, "Location provider is: " + isGPSEnabled);

            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
                    ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                // TODO: Consider calling
                //    ActivityCompat#requestPermissions
                // here to request the missing permissions, and then overriding
                //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                //                                          int[] grantResults)
                // to handle the case where the user grants the permission. See the documentation
                // for ActivityCompat#requestPermissions for more details.

                Log.e(TAG, "== Error On onConnected() Permission not granted");
                //Permission not granted by user so cancel the further execution.
                return;
            }


            Criteria criteria = new Criteria();
            criteria.setAccuracy(Criteria.ACCURACY_FINE);
            criteria.setPowerRequirement(Criteria.NO_REQUIREMENT);
            criteria.setAltitudeRequired(false);
            criteria.setSpeedRequired(true);
            //setCostAllowed(true): This flag enables LocationManager to exchange “data packet” with
            // 3G/4G network base stations in order to get better location
            criteria.setCostAllowed(true);
            criteria.setBearingRequired(false);

            //API level 9 and up
            criteria.setHorizontalAccuracy(Criteria.ACCURACY_HIGH);
            criteria.setVerticalAccuracy(Criteria.ACCURACY_HIGH);

            String provider = locationManager.getBestProvider(criteria, true);

//          locationManager.requestLocationUpdates(gpsFreqInMillis, gpsFreqInDistance, criteria, locationListener, null);

            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
                    0, this);
            Log.i(TAG, "request for location updates..");
        } catch (SecurityException | IllegalArgumentException e) {
            Log.e(TAG, "Exception inside createAndRequestLocationUpdates(): " + e);
        }
    }

不要将Location类存储在共享首选项中就我而言，这就是问题所在

Answer 2

According to the documentation RuntimeException is called when calling thread has no Looper. Try to call Looper.prepare() before you call LocationManager
