8.1.2 Add a Location Listener

1. Build a Google Play Services client that includes the LocationServices API.

public class WearableActivity extends Activity implements

GoogleApiClient.ConnectionCallbacks,

GoogleApiClient.OnConnectionFailedListener

LocationListener {

GoogleApiClient googleClient;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_handheld);

// Build a new GoogleApiClient

googleClient = new GoogleApiClient.Builder(this)

.addApi(LocationServices.API)

.addConnectionCallbacks(this)

.addOnConnectionFailedListener(this)

.build();

}

// Location listener implementation (Step 2)

...

}

2. Register a location listener for the Fused Location API.

// Connect to Google Play Services when the Activity starts

@Override

protected void onStart() {

super.onStart();

googleClient.connect();

}

// Register as a listener when connected

@Override

public void onConnected(Bundle connectionHint) {

// Create the LocationRequest object

LocationRequest locationRequest = LocationRequest.create();

// Use high accuracy

locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

// Set the update interval to 2 seconds

locationRequest.setInterval(TimeUnit.SECONDS.toMillis(2));

// Set the fastest update interval to 2 seconds

locationRequest.setFastestInterval(TimeUnit.SECONDS.toMillis(2));

// Set the minimum displacement

locationRequest.setSmallestDisplacement(2);
