必须调用Android WearableListenerService两次才能接收Message

我从手持设备向服务发送消息。 我第一次点击掌上电脑上的按钮只是调用服务的onCreate方法,第二次服务也收到消息。我无法弄清楚问题。

这是我的磨损部分:

    @Override
    public void onClick(View v)
    {
        final PendingResult<NodeApi.GetConnectedNodesResult> nodes1 = Wearable.NodeApi.getConnectedNodes(mApiClient);
        nodes1.setResultCallback(new ResultCallback<NodeApi.GetConnectedNodesResult>()
        {
            @Override
            public void onResult(NodeApi.GetConnectedNodesResult result)
            {
                for (int i = 0; i < result.getNodes().size(); i++)
                {
                    Node node = result.getNodes().get(i);

                    PendingResult<MessageApi.SendMessageResult> messageResult = Wearable.MessageApi.sendMessage(mApiClient, node.getId(), "/OPEN;"
                            + cnt, null);
                    messageResult.setResultCallback(new ResultCallback<MessageApi.SendMessageResult>()
                    {
                        @Override
                        public void onResult(MessageApi.SendMessageResult sendMessageResult)
                        {
                            Status status = sendMessageResult.getStatus();
                            Log.d("", "##Status: " + status.toString());
                            if (status.getStatusCode() != WearableStatusCodes.SUCCESS)
                            {
                                //not getting there, always success
                            }
                        }
                    });
                }
            }
        });
    }

我有以下WearableListenerService:

public class DataLayerListenerService extends WearableListenerService implements ConnectionCallbacks, OnConnectionFailedListener
{
    private GoogleApiClient mApiClient;
    private SharedPreferences prefs;

    @Override
    public void onCreate()
    {
        Log.d("", "##DataService created");
        super.onCreate();
        if (null == mApiClient)
        {
            mApiClient = new GoogleApiClient.Builder(this).addApi(Wearable.API).addConnectionCallbacks(this).addOnConnectionFailedListener(this)
                    .build();
        }

        if (!mApiClient.isConnected())
        {
            mApiClient.connect();
            Log.d("", "##Api connecting");
        }
    }

    @Override
    public void onDestroy()
    {
        Log.d("", "##DataService destroyed");
        if (null != mApiClient)
        {
            if (mApiClient.isConnected())
            {
                mApiClient.disconnect();
            }
        }
        super.onDestroy();
    }

    @Override
    public void onMessageReceived(MessageEvent messageEvent)
    {
        Log.d("", "##DataService received " + messageEvent.getPath());
        super.onMessageReceived(messageEvent);
        if (messageEvent.getPath().contains("/OPEN;"))
        {
            // only if called twice :(
        }
    }

    @Override
    public void onDataChanged(DataEventBuffer dataEvents)
    {
        Log.d("", "##DataService Data changed");
    }


    @Override
    public void onConnectionFailed(ConnectionResult arg0)
    {
    }

    @Override
    public void onConnected(Bundle arg0)
    {
    }

    @Override
    public void onConnectionSuspended(int arg0)
    {
    }
}

也许我还应该提一下,当服务被破坏之前我必须点击两次按钮,这发生在点击事件后几秒钟。 所以......实际上就是这样:

  

点击

     

service oncreate

     

点击

     

service onMessageReceived

     

点击

     

service onMessageReceived

     

//等待几秒钟

     

service ondestroy

     

点击

     

service oncreate

     

点击

     

service onMessageReceived

希望这很清楚: - )

提前致谢!!

我想我可能已经解决了它Phillip Adam - 尝试在onMessageReceived()方法中对你的服务中的行进行注释,该方法调用超类。这适合我。 :)

我一直在搞这个,如果你仍然遇到第一次尝试没有触发的监听器服务的错误,我发现增加超时间隔会有所帮助。我将我的设置设置为10毫秒,但是将其设置为更大的值似乎有所帮助。

查看我为项目创建的WearableMainActivity.java in this gist中的代码。祝好运! :)
