【问题描述】：
我有一个基本的 Android Wear 应用程序，它成功地使用可穿戴数据层在移动设备和 Wear 之间发送和接收消息。
但是，每当我（从移动设备或 Wear 设备）发送消息时，另一端都会多次收到消息（例如 5-17 的任何时间）。为什么不是只收到一次？据我所知，它只发送一次。
成功连接后，这是我的发送消息代码（两端相同）：
private void sendMsgToWear(final String strMsg){
new AsyncTask<Void, Void, List<Node>>(){
@Override
protected List<Node> doInBackground(Void... params) {
return getNodes();
}
@Override
protected void onPostExecute(List<Node> nodeList) {
for(Node node : nodeList) {
Log.v("DEVELOPER", "......Phone: Sending Msg: " + strMsg + " to node: " + node.getId());
PendingResult<MessageApi.SendMessageResult> result = Wearable.MessageApi.sendMessage(
mGoogleApiClient,
node.getId(),
strMsg,
null
);
result.setResultCallback(new ResultCallback<MessageApi.SendMessageResult>() {
@Override
public void onResult(MessageApi.SendMessageResult sendMessageResult) {
Log.v("DEVELOPER", "......Phone: " + sendMessageResult.getStatus().getStatusMessage());
}
});
}
}
}.execute();
}
private List<Node> getNodes() {
List<Node> nodes = new ArrayList<Node>();
NodeApi.GetConnectedNodesResult rawNodes =
Wearable.NodeApi.getConnectedNodes(mGoogleApiClient).await();
for (Node node : rawNodes.getNodes()) {
nodes.add(node);
nodeID = node.getId();
}
return nodes;
}
这是我在实现 MessageApi.MessageListener 的活动上接收的方式：
@Override
public void onMessageReceived(MessageEvent messageEvent) {
Log.d("DEVELOPER", "......Wear: successfully received phone to wear communication!");
}
我在发送端的输出如下所示：
07-11 10:54:57.646 26920-28711/com.wearTest.message V/DEVELOPER﹕ ......Phone: Sending Msg: testMessage to node: 6ecc099a-60f8-4c3d-90fe-fa2f248c6bf7
07-11 10:54:57.666 26920-26920/com.wearTest.message V/DEVELOPER﹕ ......Phone: null
以及接收端日志：

提前致谢！
【问题讨论】：

以防万一，您是否检查过您只注册了一次接收方？
-
啊，谢谢马蒂亚什！白骨移动，就是这样。
-
我很高兴这很容易。 :) 你打算删除这个问题，还是我应该添加一个答案？
-
继续添加一个让我接受的答案...它将为其他可怜的灵魂节省一小时徒劳的工作！
