Question

我试图使用MessageAPI向我的手机发送一些字符串。然而，该消息在75％的时间内未能达到磨损。这是问题，它的行为至少对我来说是不可预测的。决定消息是否到达的因素是未知的。我已经阅读了之前的答案，并在发送信息之前尝试检查手表和手机是否已连接，但这也没有奏效。两者都有明显的联系，但仍然没有达到消息。以下是我的手机应用程序中的代码：

    private static void sendMessage(final String path, final String duration, final String type, final String name, final String startingTime,final Context context) {
    new Thread( new Runnable() {
        @Override
        public void run() {

            Bundle inBundle = new Bundle();
            inBundle.putString("duration", duration);
            inBundle.putString("type", type); // will be failed
            inBundle.putString("name", name); // will be failed
            inBundle.putString("Starting Time", startingTime);
            inBundle.putBoolean("Stop", false);

            // From Bundle to bytes
            byte[] inBytes = bundleToBytes(inBundle);

            NodeApi.GetConnectedNodesResult nodes = Wearable.NodeApi.getConnectedNodes( mGoogleApiClient ).await();

            for(Node node : nodes.getNodes()) {
                MessageApi.SendMessageResult result = Wearable.MessageApi.sendMessage(
                        mGoogleApiClient, node.getId(), path, inBytes ).await();


                Log.i("Node:",nodes.getNodes().toString());
            }

            Wearable.NodeApi.addListener(mGoogleApiClient, new NodeApi.NodeListener() {
                @Override
                public void onPeerConnected(Node node) {
                    Log.i("Node:","Ab connected");
                }

                @Override
                public void onPeerDisconnected(Node node) {

                }
            });

        }
    }).start();
}

以下是我的Android Wear的留言接收代码：

    public void onMessageReceived(MessageEvent messageEvent) {
    if( messageEvent.getPath().equalsIgnoreCase( START_ACTIVITY ) ) {
        Intent intent = new Intent( this, MainActivity.class );
        intent.addFlags( Intent.FLAG_ACTIVITY_NEW_TASK );
        startActivity( intent );

        Bundle outBundle = jsonStringToBundle(new String(messageEvent.getData()));

        String duration = outBundle.getString("duration");
        stop=outBundle.getBoolean("Stop");
        String type = outBundle.getString("type");
        String name = outBundle.getString("name");
        String startingTime= outBundle.getString("Starting Time");

        Bundle b= new Bundle();
        b.putInt("duration", Integer.parseInt(duration));
        b.putString("Starting Time",startingTime);

        Toast.makeText(getApplicationContext(),duration + " : " + startingTime,Toast.LENGTH_SHORT).show();


        if(!stop) {
            AcquisitionStatus=true;
            Intent sensorServ = new Intent(MyService.this, SensorService.class);
            sensorServ.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_NO_HISTORY);
            sensorServ.putExtras(b);
            startService(sensorServ);

        }
        else {
            AcquisitionStatus = false;
           // setAcquisitionStatus(false);
        }

    }
    else if (  messageEvent.getPath().equalsIgnoreCase("TestPath") )
    {
        Toast.makeText(getApplicationContext(),"HELLO!",Toast.LENGTH_SHORT).show();

    }
    else {
        super.onMessageReceived( messageEvent );
    }
}

尝试以下两种方法之一：

尝试设置＆＃34; setResultCallback＆＃34;当您发送邮件并检查是否收到回复时。
您可以使用Data API，因为Data API提供100％保证，而Message API有时会被丢弃。此外，Data API会比较先前和当前数据，并仅在至少有一个数据发生更改时才会发送。

您可以使用Data API并将数据发送为

PutDataMapRequest putDataMapRequest = PutDataMapRequest.create(*WEAR_ID*);
putDataMapRequest.getDataMap().putString("duration", duration);
putDataMapRequest.getDataMap().putString("type", type);
putDataMapRequest.getDataMap().putString("name", name); 
putDataMapRequest.getDataMap().putString("Starting Time", startingTime);
putDataMapRequest.getDataMap().putBoolean("Stop", false);

发送给Android Wear的消息会丢失
