LocationClient requestUpdates onLocationChanged never called

Question

I have this code that I use to host the map application. I tested it on a Galaxy S2 device and worked great, but when I tested it on a nexus 4 device, callback onLocationChanged never called. What can i do wrong?

Here is my activity code:

  public class BaseMapActivity extends FragmentActivity implements Injectable, GooglePlayServicesClient.ConnectionCallbacks, GooglePlayServicesClient.OnConnectionFailedListener, LocationListener { private final static int CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000; private MapEntity component; private boolean yetStarted = false; private LocationClient mLocationClient; private LocationRequest mLocationRequest; private Location location; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.map_activity); mLocationClient = new LocationClient(this, this, this); mLocationRequest = LocationRequest.create(); mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); // TODO mLocationRequest.setInterval(5000); // TODO mLocationRequest.setFastestInterval(5000); // TODO replaceFragment(R.id.map_container, mapFragment); // Agrega el fragment de extras Fragment extrasFragment = component.getExtrasFragment(); replaceFragment(R.id.map_extras, extrasFragment); } @Override protected void onStart() { super.onStart(); mLocationClient.connect(); } @Override protected void onStop() { if (mLocationClient.isConnected()) { mLocationClient.removeLocationUpdates(this); mLocationClient.disconnect(); } super.onStop(); } @Override public void onConnected(Bundle arg0) { mLocationClient.requestLocationUpdates(mLocationRequest, this); location = mLocationClient.getLastLocation(); if (location == null) { return; } Toast.makeText(this, "onConnected", Toast.LENGTH_SHORT).show(); } @Override public void onDisconnected() { mLocationClient.removeLocationUpdates(this); Toast.makeText(this, "onDisconnected. Please re-connect.", Toast.LENGTH_SHORT).show(); } @Override public void onLocationChanged(Location location) { component.setCenter(location); String msg = "Updated Location: " + Double.toString(location.getLatitude()) + "," + Double.toString(location.getLongitude()); Toast.makeText(this, msg, Toast.LENGTH_SHORT).show(); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case CONNECTION_FAILURE_RESOLUTION_REQUEST: switch (resultCode) { case Activity.RESULT_OK: break; } } } @SuppressLint("ShowToast") @Override public void onConnectionFailed(ConnectionResult connectionResult) { if (connectionResult.hasResolution()) { try { connectionResult.startResolutionForResult(this, CONNECTION_FAILURE_RESOLUTION_REQUEST); } catch (IntentSender.SendIntentException e) { e.printStackTrace(); } } else { Toast.makeText(this, "An error ocurred getting current location", Toast.LENGTH_SHORT); } } } 

It is strange that it works on one device, but not in another.

Try setting the location layout to see if locationChange is being called or not.

Here you have an example that I used to do this before production.

 private Location createMockLocation() { if (mockLocation == null) { mockLocation = new Location("mock"); mockLocation.setLatitude(41.4934133); mockLocation.setLongitude(-23.8729252); mockLocation.setAccuracy(1.0f); mockLocation.setTime(new Date().getTime()); } else { mockLocation.setLatitude(mockLocation.getLatitude() + 0.00003); mockLocation.setLongitude(mockLocation.getLongitude() + 0.00001); mockLocation.setTime(new Date().getTime()); } return mockLocation; } private void mockLocation() { LocationServices.FusedLocationApi.setMockMode(clientApi, true); LocationServices.FusedLocationApi.setMockLocation(clientApi, createMockLocation()); final ScheduledExecutorService scheduler = Executors.newSingleThreadScheduledExecutor(); scheduler.scheduleAtFixedRate(new Runnable() { public void run() { LocationServices.FusedLocationApi.setMockLocation(clientApi, createMockLocation()); // Log.d("MockLocation", // "mockLocation: Lat:"+mockLocation.getLatitude()+" Long:"+mockLocation.getLongitude()); } }, 0, NORMAL_INTERVAL, TimeUnit.MILLISECONDS); } 

Using this method, you get the update position, each NORMAL_INTERVAL in ms.

Hope this helps :).
