从移动中获取输出 - 活动 -
System.out﹕ syncing successful....Status{statusCode=SUCCESS, resolution=null}
但它显示没有对Wear - 活动的反应（想要在设备已同步的机器人佩戴上显示某些内容）。
以下是Wear - activity
的代码public class NotificationUpdateService extends WearableListenerService{
private int notificationId = 001;
@Override
public void onDataChanged(DataEventBuffer dataEvents)

{
DataMap dataMap = DataMapItem.fromDataItem(dataEvent.getDataItem()).getDataMap();
String title = dataMap.getString("title");
String content = dataMap.getString("content");
System.out.println("title: "+title+" content: "+content);
sendNotification(title, content);
}
}
}
private void sendNotification(String title, String content)
{
Intent viewIntent = new Intent(this, MainActivity.class);
PendingIntent pendingViewIntent = PendingIntent.getActivity(this, 0, viewIntent, 0);
// this intent will be sent when the user swipes the notification to dismiss it

答案 0 :(得分：0)
你有一行＆＃34; mGoogleApiClient.connect（）;＆＃34;注释掉并因此无法保证可以访问Play服务WearableAPI
此外，有两个主要原因导致onDataChanged无法在Android服装设备上触发1）您正在使用的DataItem＆＃34; put＆＃34;自上次将其放入DataLayer以来，还没有更改过。尝试添加时间戳以避免此问题以进行调试。 2）套装名称和签名在wear apk和mobile apk上不一样。尽你所能确保两个模块上的相同。

确保可穿戴应用程序和手持式应用程序模块具有相同的程序包名称和版本号。如果您使用Gradle构建，请同时检查项目的可穿戴和手持应用程序模块上applicationId versionName和versionCode个文件中的build.gradle，12-31 05:11:36.314 26809-26809/com.androidatc.customviewindrawer E/AndroidRuntime: java.lang.IllegalStateException: Could not find a method loginUser(View) in the activity class com.androidatc.customviewindrawer.MainActivity for onClick handler on view class android.widget.Button with id 'btnLogin'
