Android Wear与手机硬件通信

Question

Hi I have this simple code on Android Wear I need a bit of help everything works well if I'm using the phone alone the problem I have is that I taught Android wear will use automatically the Phone hardware for sound and all that good stuff. Here is my test code

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final WatchViewStub stub = (WatchViewStub)     findViewById(R.id.watch_view_stub);
stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
    @Override
    public void onLayoutInflated(WatchViewStub stub) {

        imageButtonOne = (ImageButton) findViewById(R.id.imageButtonOne);
        textviewOne = (TextView) findViewById(R.id.textviewOne);
        imageButtonOne.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                textviewOne.setText("Hello World!");
                soundOne() ;
            }
        });
    }
    public void soundOne() {
        try {
            Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
            Ringtone one = RingtoneManager.getRingtone(getApplicationContext(), notification);
            one.play();
        } catch (Exception e) {
            e.printStackTrace();
        }
        // MediaPlayer media = MediaPlayer.create(this, R.raw.sound_file_1);
        // media.start() ;
        // Toolkit.getDefaultToolkit().beep() ;
    }
});

It call the sound but because watches doesn't have speakers won't sound. I want the phone to make the sound. Please if someone can help me will be appreciated.

While Android Wear devices will play sound if a bluetooth headset is attached, if you need sound to play on the phone you need to use the Wearable Data Layer and probably more specifically the Message API to send a message to your phone app. Your phone app would implement a WearableListenerService which would be triggered by the incoming message and would play the sound on the phone.

Note: it is much more common for Wear apps to vibrate (via the Vibrator to draw attention rather than play sounds on the phone. Many Wear users use the 'Mute connected phone' option to effectively silence their phone so a sound coming from it may be quite unexpected.
