Question

我遇到了Google安卓数据层Api的问题......

我已经用它来从可穿戴活动中调用手持活动，它运行得很好。但现在我想通过表盘服务拨打手持设备......

我创建了一个Google API客户端并添加了wearableApi：

     public void onCreate(SurfaceHolder holder) {
        super.onCreate(holder);

        setWatchFaceStyle(new WatchFaceStyle.Builder(MyWatchFace.this)
                .setCardPeekMode(WatchFaceStyle.PEEK_MODE_VARIABLE)
                .setBackgroundVisibility(WatchFaceStyle.BACKGROUND_VISIBILITY_INTERRUPTIVE)
                .setShowSystemUiTime(false)
                .setAcceptsTapEvents(true)
                .build());
        mGoogleApiClient = new GoogleApiClient.Builder(MyWatchFace.this)
                .addApi(Wearable.API)
                .build();
        mGoogleApiClient.connect();

然后我使用这些方法发送数据：

    public void startActivity()
    {
        HashSet<String> results = new HashSet<String>();

        Wearable.NodeApi.getConnectedNodes(mGoogleApiClient).setResultCallback(new ResultCallback<NodeApi.GetConnectedNodesResult>() {
            @Override
            public void onResult(NodeApi.GetConnectedNodesResult getConnectedNodesResult) {
                String handheld = getConnectedNodesResult.getNodes().get(0).getId();
                Toast.makeText(MyWatchFace.this, getConnectedNodesResult.getNodes().get(0).getDisplayName()+": "+ handheld, Toast.LENGTH_SHORT).show();
                sendStartActivityMessage(handheld, giveValueXYZ());

            }
        });

private void sendStartActivityMessage(String nodeId, String data) {
        byte[] dataArray = data.getBytes();
        Toast.makeText(MyWatchFace.this, "ActivityPath: "+ START_ACTIVITY_PATH, Toast.LENGTH_SHORT).show();
        Wearable.MessageApi.sendMessage(

                mGoogleApiClient, nodeId, START_ACTIVITY_PATH, dataArray).setResultCallback(
                new ResultCallback<MessageApi.SendMessageResult>() {
                    @Override
                    public void onResult(MessageApi.SendMessageResult sendMessageResult) {
                        if (!sendMessageResult.getStatus().isSuccess()) {
                            Log.e(TAG, "Failed to send message with status code: "
                            + sendMessageResult.getStatus().getStatusCode());
                        }
                    }

                });
    }

在移动网站上，我使用此代码来收听消息：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_host_main);
    context = getApplicationContext();

    ...

    //Google Api
    final GoogleApiClient googleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Wearable.API).build();
    googleApiClient.connect();

    Wearable.MessageApi.addListener(googleApiClient, this);

...

public void onMessageReceived(MessageEvent messageEvent) {

    if (messageEvent.getPath().equals(START_ACTIVITY_PATH_WEARDATA)) {
        Log.d(TAG, "getPath: " + messageEvent.getPath() + "|||getData: " + messageEvent.getData());

        someActions();
    }

如果我从可穿戴活动发送消息但是如果我从watchface服务发送消息，则甚至不会触发onMessageReceived（...）方法，这一切都能正常工作......

我的包裹名称可能有问题吗？
mobile：com.example.janik.xxx.xxx

watchface：de.WatchSmart.watch_smart_watch_face_service

客户如何知道向他发送了哪条数据层Api消息？
