[android-developers] Mock Location Service only works for google maps

[Daniel Schindler]

Hi,

I have got a problem with my mock location service.
It should mock the location for an other app, but it only works for google 
maps.
I know that the "other app" is not the problem, because "Fake GPS" is able 
to mock it.

AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android";
    package="user.tpmockvuln">

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <service
            android:name=".MockService"
            android:enabled="true"
            android:exported="true"
            android:icon="@drawable/ic_check_circle_black_24px"></service>
    </application>

</manifest>

MockService:
public class MockService extends Service implements 
GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener 
{

    private GoogleApiClient mGoogleApiClient;
    private Location mockLocation;

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }


    @Override
    public void onCreate() {

        // Create an instance of GoogleAPIClient.
        if (mGoogleApiClient == null) {
            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    .addApi(LocationServices.API)
                    .build();
        }
    }

    @Override
    public void onDestroy() {
        if (ActivityCompat.checkSelfPermission(this, 
Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                && ActivityCompat.checkSelfPermission(this, 
Manifest.permission.ACCESS_COARSE_LOCATION) != 
PackageManager.PERMISSION_GRANTED) {
        } else {
            LocationServices.FusedLocationApi.setMockMode(mGoogleApiClient, 
false);
        }
        mGoogleApiClient.disconnect();
        super.onDestroy();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        mGoogleApiClient.connect();
        return super.onStartCommand(intent,flags,startId);
    }

    private void mockLocation(double latitude, double longitude, float speed) {
        if (ActivityCompat.checkSelfPermission(this, 
android.Manifest.permission.ACCESS_FINE_LOCATION) != 
PackageManager.PERMISSION_GRANTED
                && ActivityCompat.checkSelfPermission(this, 
Manifest.permission.ACCESS_COARSE_LOCATION) != 
PackageManager.PERMISSION_GRANTED) {
        } else {
            mockLocation = new Location(LocationManager.NETWORK_PROVIDER);
            mockLocation.setLatitude(latitude);
            mockLocation.setLongitude(longitude);
            mockLocation.setSpeed(speed);
            mockLocation.setAltitude(0);
            mockLocation.setAccuracy(500);
            mockLocation.setTime(System.currentTimeMillis());
            
mockLocation.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());
            mockLocation.setBearing(10);
            mockLocation.setProvider(LocationManager.NETWORK_PROVIDER);

            LocationServices.FusedLocationApi.setMockMode(mGoogleApiClient, 
true);
            LocationServices.FusedLocationApi.setMockLocation(mGoogleApiClient, 
mockLocation);
        }
    }

    @Override
    public void onConnected(@Nullable Bundle bundle) {
        mockLocation(48.133357, 11.573496, 0);
    }

    @Override
    public void onConnectionSuspended(int i) {
    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
    }
}

call from activity:
public void run(View view) {
    statusTextView.setText("running");
    intent = new Intent(this, MockService.class);
    startService(intent);
}

Thank you for your help
