// Register listener using the LocationRequest object

LocationServices.FusedLocationApi.requestLocationUpdates(googleClient, locationRequest, this);

}

// Disconnect from Google Play Services when the Activity stops

@Override

protected void onStop() {

if (mGoogleApiClient.isConnected()) {

LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);

googleClient.disconnect();

}

super.onStop();

}

// Placeholders for required connection callbacks

@Override

public void onConnectionSuspended(int cause) { }

@Override

public void onConnectionFailed(ConnectionResult connectionResult) { }

3. Implement the LocationListener callback for location updates.

@Override

public void onLocationChanged(Location location){

// Display the latitude and longitude in the UI

mTextView.setText("Latitude: " + String.valueOf( location.getLatitude()) +

"\nLongitude: " + String.valueOf( location.getLongitude()));

}

This example displays the current latitude and longitude in the wearable UI. The location is from the handheld GPS.

When the wearable is not paired with the handheld, for example when you leave the wearable behind to exercise, the

GPS automatically switches to the onboard GPS.

This screen capture is from the Sony SmartWatch 3. The number of digits displayed is greater now, providing a visual

clue that the wearable GPS is active. When you return and re-pair with the handheld, the GPS automatically switches

back to the handheld and the display returns to its original format.
