Android WearListenerService OnData改变了奇怪的行为

我想在Android Wear和掌上电脑之间进行双向数据传输。 除了在掌上电脑上改变触发数据外，一切似乎都很好。只有当我插入\拔出USB电缆并连接到电脑时，它才会触发。 所以我不明白为什么会这样

这是我的密码：

请告诉我，我做错了什么

解决方案

我重写了SendtoAtatalayerthread。现在它是一个常规类，没有扩展线程，DataRequest变得很紧急：

class SendToDataLayerThread
    {
        String path;
        DataMap dataMap;

        // Constructor for sending data objects to the data layer
        SendToDataLayerThread(String p, DataMap data)
        {
            path = p;
            dataMap = data;
        }

        public void run()
        {
            //NodeApi.GetConnectedNodesResult nodes = Wearable.NodeApi.getConnectedNodes(googleClient);
            PendingResult<NodeApi.GetConnectedNodesResult> nodes = Wearable.NodeApi.getConnectedNodes(googleClient);
            nodes.setResultCallback(new ResultCallback<NodeApi.GetConnectedNodesResult>()
            {
                @Override
                public void onResult(NodeApi.GetConnectedNodesResult getConnectedNodesResult)
                {
                    for (Node node : getConnectedNodesResult.getNodes())
                    {

                        final Node node2 = node;

                        // Construct a DataRequest and send over the data layer
                        PutDataMapRequest putDMR = PutDataMapRequest.create(path);
                        putDMR.getDataMap().putAll(dataMap);
                        PutDataRequest request = putDMR.asPutDataRequest();
                        request.setUrgent();

                        PendingResult<DataApi.DataItemResult> pendingResult = Wearable.DataApi.putDataItem(googleClient, request);
                        pendingResult.setResultCallback(new ResultCallback<DataApi.DataItemResult>()
                        {
                            @Override
                            public void onResult(DataApi.DataItemResult dataItemResult)
                            {
                                if (dataItemResult.getStatus().isSuccess())
                                {
                                    Log.v("DataMap: " + dataMap + " sent to: " + node2.getDisplayName());
                                } else
                                {
                                    // Log an error
                                    Log.v("ERROR: failed to send DataMap");
                                }
                            }
                        });
                    }
                }
            });
        }
    }

谢谢你的帮助

根据：

使用GooglePlayServices8.3，我们更新了DataApi，以便在同步数据项时考虑到紧迫性。现在，可以向数据项添加优先级，以确定何时应同步该数据项。例如，如果您正在构建一个需要立即同步的应用程序，例如远程控制应用程序，仍然可以通过调用setUrgent（）立即完成同步，但对于更新联系人之类的操作，您可以容忍一些延迟非紧急数据项可能会延迟30分钟，但在大多数情况下，它们会在几分钟内送达低优先级现在是默认值，因此需要获取上一个计时

---

因此，如果您希望数据请求立即同步到其他连接的设备，请确保调用数据请求。

哇，谢谢，这解决了手持设备上的问题！（我将其添加到手持设备和穿戴设备中）。现在它立即触发了数据更改。在我将数据发送到掌上电脑后，我的穿戴是无声的。我试图在手持设备上重写发送过程，就像它在磨损一样，但什么都没有。现在我已经更改了手持设备的磨损请求。从日志中（与问题类似），我看到请求已成功发送到正确的设备，但onDataChanged on wear未接收到请求（无论是否使用setUrgent（））。若我通过MessageApi从手持设备发送消息，那个么它将被磨损的附加onMessageReceived接收。我想知道一个秘密，为什么MessageApi工作得很好，而DataAPI在某个地方丢失了。我发现数据可以通过以下修改之一达到磨损：在发送数据后，在手持设备上制作googleapi disconnect（）和connect（），或者将Thread.start（）替换为Thread.run（）我甚至不知道，当有异步版本可以用来代替在线程上调用

await（）

时，为什么要旋转整个新线程。
