I`m trying to do like in this manual [PushMe](https://developer.android.com/training/location/retrieve-current.html#play-services) but something wrong happening.

FATAL EXCEPTION: main

```
java.lang.RuntimeException: Unable to start activity ComponentInfo{tk.i7otep9wka.testgeo/tk.i7otep9wka.testgeo.MainActivity}: java.lang.ClassCastException: tk.i7otep9wka.testgeo.MainActivity cannot be cast to com.google.android.gms.common.api.GoogleApiClient$ConnectionCallbacks

```

MainActivity

```

        GooglePlayServicesClient.ConnectionCallbacks,
        GooglePlayServicesClient.OnConnectionFailedListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        buildGoogleApiClient();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
    protected synchronized void buildGoogleApiClient() {
            GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks((GoogleApiClient.ConnectionCallbacks) this)
                .addOnConnectionFailedListener((GoogleApiClient.OnConnectionFailedListener) this)
                .addApi(LocationServices.API)
                .build();
    }

    @Override
    public void onConnected(Bundle bundle) {

    }

    @Override
    public void onDisconnected() {

    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {

    }
}

```
