MockLocation testProvider does not call onLocationChanged

Question

I am targeting Google API 2.3.3 and have the following class of tests

import android.content.Context;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.location.LocationProvider;
import android.os.Bundle;
import android.provider.Settings;
import android.test.AndroidTestCase;
import android.util.Log;

public class MockLocationManagerTests extends AndroidTestCase implements LocationListener{

    private static final String TAG = "MockLocationTests";
    private String locationProvider = "TestProvider";
    private LocationManager locationManager;
    private Location lastLocation;

    protected void setUp() throws Exception {
        super.setUp();
        locationManager = (LocationManager) getContext().getSystemService(Context.LOCATION_SERVICE);
         if (Settings.Secure.getInt(getContext().getContentResolver(), Settings.Secure.ALLOW_MOCK_LOCATION, 0) == 0) {
                 fail("Mock location must be enabled");
        }
        setupLocationManager();
    }

    private void setupLocationManager() {
        if (locationManager.getProvider(locationProvider) != null) {
            locationManager.removeTestProvider(locationProvider);
        }

        locationManager.addTestProvider(locationProvider, 
                                        false, 
                                        true, 
                                        false, 
                                        false, 
                                        false, 
                                        false, 
                                        false, 
                                        Criteria.POWER_LOW, 
                                        Criteria.ACCURACY_FINE);
        locationManager.requestLocationUpdates(locationProvider, 0, 0, this);
        locationManager.setTestProviderStatus(locationProvider, LocationProvider.AVAILABLE, null, System.currentTimeMillis());
        locationManager.setTestProviderEnabled(locationProvider, true);
    }

    private Location createLocation(double lat, double lon) {
        Location location = new Location(locationProvider);
        location.setLatitude(lat);
        location.setLongitude(lon);
        location.setAltitude(0);
        location.setTime(System.currentTimeMillis());
        return location;
    }

    protected void tearDown() throws Exception {
        super.tearDown();
    }

    public final void testCanObserveLocationChanging() throws InterruptedException {
        Location l = createLocation(19,-2);
        locationManager.setTestProviderLocation(locationProvider,l);
        synchronized(this){
            wait(5000);
        }
        Location l2 = createLocation(1,-10);
        locationManager.setTestProviderLocation(locationProvider,l2);
        synchronized(this){
            wait(5000);
        }
        assertEquals(l,lastLocation);
    }

    public void onLocationChanged(Location location) {
        Log.i(TAG,"location changed");
        lastLocation = location;        
    }

    public void onProviderDisabled(String provider) {
        Log.i(TAG, provider+" disabled");
    }

    public void onProviderEnabled(String provider) {
        Log.i(TAG, provider+" enabled");
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {
        Log.i(TAG,"status changed: "+provider+" to "+status);
    }
}

onLocationChanged is not being called, and my google-fu and brain-fu are not giving me the opportunity. Any advice that is much appreciated

UPDATE

None of the log messages get caught, so onStatusChanged and onProviderEnabled are not triggered?

If I call getLastKnownLocation()between calls to setTestProviderLocation(), locationManager returns the location I specified

OTHER UPDATE

If I add a class that uses this code for my application, onLocationChanged () is called. The only difference is that I do not use Mock_Location. So it seems that setTestProviderLocation () is not calling onLocationChanged () to run

Answer 1

Google API 19.

AndroidTestCase Looper . ActivityInstrumentationTestCase2 ThreadLooper AndroidTestCase .

Looper mLooper; 
HandlerThread thread = new HandlerThread("LocationHandlerThread");
thread.start(); // starts the thread.
mLooper = thread.getLooper();

Looper requestLocationUpdates:

mLocationManager.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER, 0, 0, mLocationListener, mLooper);

Answer 3

Just click "Submit" on the eclipse emulator control tab to send the coordinates to the application.
