Android Studio Emulator crashes on LocationServices.fusedLocationApi

Question

So I have a Google Maps application in android studio and I am trying to set it up. I looked at Treehouse how they set it up with googles own location provider and everything that is necessary http://blog.teamtreehouse.com/beginners-guide-location-android

I have done everything it says and it works fine on my cellphone but the emulator crashes on startup and it says the fault is in the line

LocationServices.FusedLocationApi.requestLocationUpdates(this.mGoogleApiClient, this.mLocationRequest, this);

I dont know what I should do. I've even used the console to geo fix a location to the gps in the emulator but nothing. Here is my complete code

public class Guide extends AppCompatActivity implements
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener,
    LocationListener


private GoogleMap           mMap; // Might be null if Google Play services APK is not available.
private GoogleApiClient     mGoogleApiClient;
private LocationRequest     mLocationRequest;
private LatLng              currentPos;

private boolean             centerCamera;
private boolean             isSatelliteChecked = false;

public static final String TAG = Guide.class.getSimpleName();
private final static int CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_guide);
    this.centerCamera = true;
    setUpMapIfNeeded();

    // Create the Google API Client
     mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();
    // Create the LocationRequest object
    mLocationRequest = LocationRequest.create()
            .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
            .setInterval(10 * 1000)        // 10 seconds, in milliseconds
            .setFastestInterval(1000); // 1 second, in milliseconds

Answer 1

Your emulator might not have google play services. This may help: How to download Google Play Services in an Android emulator?

Answer 2

This solved the problem for me.

In gradle build I check that both play-services have the same version. Here 10.2.6

compile 'com.google.android.gms:play-services-maps:10.2.6' compile 'com.google.android.gms:play-services-location:10.2.6'
