Testing GPS in Android

Question

How do you test GPS applications in Android? Can we test it using the Android emulator?

Answer 1

in addition to Mallox code this is the sulotion for mock location in addition to real gps location : TEST_MOCK_GPS_LOCATION is a string

LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    Location location = null;

    List providers = lm.getAllProviders();
    for (Object provider : providers) {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            return;
        }
        Location loc = lm.getLastKnownLocation((String) provider);
        if  (provider.equals(TEST_MOCK_GPS_LOCATION))  {
            mLastLocation = loc;
        }
    } 

in the test class it is :

public class GPSPollingServiceTest extends AndroidTestCase {
private LocationManager locationManager;

public void testGPS() throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {
    LocationManager locationManager = (LocationManager) this.getContext().getSystemService(Context.LOCATION_SERVICE);
    List providers = locationManager.getAllProviders();
    if(!providers.contains(TEST_MOCK_GPS_LOCATION)) {
        locationManager.addTestProvider(TEST_MOCK_GPS_LOCATION, false, false, false, false, false, false, false, Criteria.POWER_LOW, Criteria.ACCURACY_FINE);
        locationManager.setTestProviderEnabled(TEST_MOCK_GPS_LOCATION, true);
        // Set up your test
        Location location = new Location(TEST_MOCK_GPS_LOCATION);
        location.setLatitude(34.1233400);
        location.setLongitude(15.6777880);
        location.setAccuracy(7);
        location.setTime(8);
        location.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());

        locationManager.setTestProviderLocation(TEST_MOCK_GPS_LOCATION, location);

        Method locationJellyBeanFixMethod = Location.class.getMethod("makeComplete");
        if (locationJellyBeanFixMethod != null) {
            locationJellyBeanFixMethod.invoke(location);
        }
    } else {
        // Check if your listener reacted the right way
        locationManager.removeTestProvider(TEST_MOCK_GPS_LOCATION);
    }
}

}

hope it will help you
