GPS Provider unknown error in Set Mock Location?

问题:

I'm trying to set my mock location however, I am getting the following error(Provider 'gps' unknown) and not to sure what is wrong?

I've got all the permission declared in my manifest.xml along with all the parameters.

Mock Location Method

 //Initiates the method to set the phones location         private void setMockLocation() {           mLocationManager.removeTestProvider(LocationManager.GPS_PROVIDER);           mLocationManager.addTestProvider                     (                     LocationManager.GPS_PROVIDER,                     "requiresNetwork" == "",                     "requiresSatellite" == "",                     "requiresCell" == "",                     "hasMonetaryCost" == "",                     "supportsAltitude" == "",                     "supportsSpeed" == "",                     "supportsBearing" == "",                      android.location.Criteria.POWER_LOW,                     android.location.Criteria.ACCURACY_FINE                     );              Location newLocation = new Location(LocationManager.GPS_PROVIDER);              newLocation.setLatitude (32.4276462);             newLocation.setLongitude(-23.5509257);              newLocation.setAccuracy(500);              mLocationManager.setTestProviderEnabled                     (                             LocationManager.GPS_PROVIDER,                             true                     );              mLocationManager.setTestProviderStatus                     (                             LocationManager.GPS_PROVIDER,                             LocationProvider.AVAILABLE,                             null,                             System.currentTimeMillis()                     );              mLocationManager.setTestProviderLocation                     (                             LocationManager.GPS_PROVIDER,                             newLocation                     );         }
