该程序使用Socket编程将陀螺仪和加速度计信息（6位数）发送到服务器。
我的问题是如何进行套接字连接并从Android Wear向服务器发送数据（使用套接字连接）
这是完整的程序::

通过这种方式，我可以使用移动电话将传感器数据发送到服务器。但是，虽然我使用 Android Wear 相同的程序，但它没有连接到套接字，因为没有INTERNET连接（因为它没有连接到WIFI）明显!!
我在stackoverflow上阅读了一些相关的主题，但我仍然不确定如何做到这一点？
相关问题：Android wear doesn't start thread
我还阅读了http://developer.android.com/training/wearables/data-layer/index.html，但仍然尝试通过互联网发送数据的最佳方式（不是蓝牙插座 - 因为人可以走出旁边范围）
任何人都可以帮我解决这个问题。
答案 0 :(得分：2)
不幸的是，这是不可能的，因为Android Wear设备无法直接访问Internet（因此无法使用套接字，HttpURLConnection或任何类似的套接字）。例如见：
唯一受支持的数据获取方式＆＃34; out＆＃34;可穿戴设备正在使用数据或消息AP，如您提到的文章（Data Layer）中所述。

您好，我必须使用GoogleApiClient创建和使用Wearable.MessageApi
我在Git repo上发布了完整的代码： - ＆gt; https://github.com/mvyas85/Fall-Alarm-Wearable
由于Wearable只能与Phone进行蓝牙连接，因此发送msg的主要方法是使用以下类，这是一个线程，并使用Wearable.MessageApi将msg从我的Android可穿戴设备发送到我的手机。然后手机上有Socket，Wifi连接到服务器。

* between apps and wearable devices. It manages this work
* on its own thread.

public class WearableMessageSender extends Thread {
private static final String TAG = "WearableMessageSender";

private DeviceData mMessage;
private GoogleApiClient mGoogleApiClient;
/**

public WearableMessageSender(String path, DeviceData msg, GoogleApiClient googleApiClient) {
a
Log.i(TAG,"Google Api is connected");
if (null == path || null == msg || null == googleApiClient) {
Log.e(TAG, "Invalid parameter(s) passed to WearableMessageSender");
throw new IllegalArgumentException("Invalid parameter(s) passed to WearableMessageSender");
}
mPath = path;
mMessage = msg;
mGoogleApiClient = googleApiClient;
}
public void run() {
// Broadcast message to call connected nodes
NodeApi.GetConnectedNodesResult nodes = Wearable.NodeApi.getConnectedNodes(mGoogleApiClient).await();
for (Node node : nodes.getNodes()) {
MessageApi.SendMessageResult result = null;
try {
result = Wearable.MessageApi.sendMessage(
mGoogleApiClient,
node.getId(),
mPath,
DeviceData.serialize(mMessage)
).await();
Log.i(TAG,"Trying to send byte arr::"+DeviceData.serialize(mMessage));
} catch (IOException e) {
e.printStackTrace();
}
if (result.getStatus().isSuccess()) {
Log.d(TAG, "Message: {" + mMessage + "} successfully sent to: " + node.getDisplayName());
} else {
