Question

在可穿戴模拟器的侦听服务的ondatachange中没有收到通过Data API从移动应用程序发送的数据。我可以发送通知，表示两者都已连接。我的代码，

DataAPI呼叫（移动）

   PutDataMapRequest putDataMapRequest = PutDataMapRequest.create(SharedConstants.START_FREE_RUN);
   putDataMapRequest.getDataMap().putString(SharedConstants.PROGRAM_TYPE,totalCountUpTimer);

    PutDataRequest request = putDataMapRequest.asPutDataRequest();
    Wearable.DataApi.putDataItem(mGoogleApiClient, request)
            .setResultCallback(new ResultCallback<DataApi.DataItemResult>() {
                @Override
                public void onResult(DataApi.DataItemResult dataItemResult) {
                    if (!dataItemResult.getStatus().isSuccess()) {
                        Log.e(TAG, "buildWatchOnlyNotification(): Failed to set the data, "
                                + "status: " + dataItemResult.getStatus().getStatusCode());
                    } else {
                        Log.d(TAG,"SuccessFully sent notification");
                    }
                }
            });

之后我收到“成功发送”的日志消息。

下面是穿着的ListenerService，

  public class ListenerService extends WearableListenerService {

  private static final String TAG =   ListenerService.class.getSimpleName();
  @Override
  public void onDataChanged(DataEventBuffer dataEvents) {
     super.onDataChanged(dataEvents);
     Log.d(TAG, "dchanged" + dataEvents);

  }
  @Override
  public void onMessageReceived(MessageEvent messageEvent) {
     Log.v(TAG, "onMessageReceivedWear: " + messageEvent);

     if  (SharedConstants.START_FREE_RUN.equals(messageEvent.getPath())) {
        // Request for this device open the attraction detail screen
        // to a specific tourist attraction
        String Distance = new String(messageEvent.getData());
        Log.d("ListenerService",Distance);

     }
 }
 }

和Android清单中的服务声明，

    <service android:name=".services.ListenerService">
        <intent-filter>
            <action android:name="com.google.android.gms.wearable.DATA_CHANGED" />
            <action android:name="com.google.android.gms.wearable.MESSAGE_RECEIVED" />
            <data android:scheme="wear" android:host="*" android:pathPrefix="*" />
       </intent-filter>
    </service>
  <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

没有在可穿戴模块中添加任何权限。建议。

Answer 1

使用android:pathPattern=".*"代替android:pathPrefix="*"

通过Data API从移动设备发送的数据未在android中收到？
