6.1.2 Implement a Message Listener

You can monitor the data layer for new messages using either a listener service or listener activity. This section

explains how to implement a listener service for messages. For the wearable, modify the code in the wear branch of

the Android Studio project.

Add Build Dependencies

Add wearable SDK dependencies to the build.gradle ﬁle (Module:wear) in the Gradle Scripts folder, as necessary.

dependencies {

compile fileTree(dir: ’libs’, include: [’

.jar’])

compile ’com.google.android.support:wearable:1.1.+’

compile ’com.google.android.gms:play-services-wearable:6.5.+’

}

Add Listener Service to Manifest

Enable the data layer listener in the manifest ﬁle.

<uses-feature android:name="android.hardware.type.watch" />

<application

...

<intent-filter>

</intent-filter>

</service>

</application>

Create a Listener Service Class

Create a listener in the wear application that extends the WearableListenerService. This example logs any received

message to the debug output.

public class ListenerService extends WearableListenerService {

@Override

public void onMessageReceived(MessageEvent messageEvent) {

if (messageEvent.getPath().equals("/message_path")) {

final String message = new String(messageEvent.getData());

Log.v("myTag", "Message path received on watch is: " + messageEvent.getPath());

Log.v("myTag", "Message received on watch is: " + message);
