未调用Android Wear onDataChanged

我下载了一个现成的手机应用程序并试图为我的Android服装项目实现一个表盘。目标是将温度信息从手机传递到磨损设备并让它更新表面。

我试过了: 1.相同的包装名称 2.相同的applicationId 3.相同的依赖版本 4.相同的权限 5.在我的手机端,我确信每次我的数据都不同(所以更新必须发生)

我也使用数据项,因此我的数据必须同步。

private void syncWatch(String min, String max, int image){
    Log.v("SunshineSyncAdapter", "syncWatch");
    String time =  String.valueOf(new Date().getTime());
    PutDataMapRequest putDataMapRequest = PutDataMapRequest.create("/weather-update");
    putDataMapRequest.getDataMap().putLong("time", new Date().getTime()); // MOST IMPORTANT LINE FOR TIMESTAMP

    putDataMapRequest.getDataMap().putString("min-temp", min + time);
    putDataMapRequest.getDataMap().putString("max-temp", max + time);
    Log.v("SunshineSyncAdapter", min + time + " " + max + time);
    PutDataRequest request = putDataMapRequest.asPutDataRequest();

    if (mGoogleApiClient == null){
        Log.v("SunshineSyncAdapter", "NOOOOOOOOOOOOOOOOO, life is no good");
        return;
    }

    Wearable.DataApi.putDataItem(mGoogleApiClient,request).setResultCallback(new ResultCallback<DataApi.DataItemResult>() {


        @Override
        public void onResult(DataApi.DataItemResult dataItemResult) {
            if (!dataItemResult.getStatus().isSuccess()) {
                Log.v("MainActivity", "Something went wrong, watch was not notified");
            } else {
                Log.v("MainActivity", "Success, Watch Notified");
            }
        }
    });
}

我首先在手机上运行我的应用程序,确保它正确运行并更新并将数据项发送到我的磨损设备。然后我运行我的wear模块并且什么也得不到,因为永远不会调用onDataChanged方法。

 @Override
    public void onDataChanged(DataEventBuffer dataEvents) {
        Log.v("SunshineWatchFace", "onDataChanged");
        try{
            for(DataEvent dataEvent: dataEvents){
                if(dataEvent.getType() != DataEvent.TYPE_CHANGED){
                    continue;
                }

                DataItem dataItem = dataEvent.getDataItem();
                if(dataItem.getUri().getPath().compareTo("weather_update") == 0){
                    DataMap dataMap = DataMapItem.fromDataItem(dataItem).getDataMap();
                    minTemp = dataMap.getString("min-temp");
                    maxTemp = dataMap.getString("max-temp");
                    weatherImage = dataMap.getInt("weather-image");
                    Log.v("SunshineWatchFace", minTemp);
                    Log.v("SunshineWatchFace", maxTemp);
                }
            }
            dataEvents.release();
            if(!isInAmbientMode()){
               invalidate();
            }
        }catch (Exception e){
            Log.v("SunshineWatchFace",e.getMessage());
        }
    }

非常感谢任何帮助

我花了很多时间试图解决这个问题。

您必须在WatchFace类中创建一个BroadcastReceiver,并在registerReceiver()方法下注册它。

首先创建BroadcastReceiver,例如:

final BroadcastReceiver mWeatherReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            // Get the data from the intent here 
            // and set the variables you're going to use in your onDraw method
        }
};

然后注册接收器,例如:

  private void registerReceiver() {

         //This is where you have the default watch face receiver 
        // Register your new weather receiver
        IntentFilter weatherFilter = new IntentFilter("ACTION_WEATHER_CHANGED");
        SunshineWatchFace.this.registerReceiver(mWeatherReceiver, weatherFilter );
    }

最后,在WatchListenerService的onDataChanged上,通过Intent将数据发送到BroadcastReceiver。例如:

        @Override
            public void onDataChanged(DataEventBuffer dataEvents) {

           // Check the data type
                    if (event.getType() == DataEvent.TYPE_CHANGED) {
                    // Get the data map
                    dataMap = DataMapItem.fromDataItem(event.getDataItem()).getDataMap();
                    Log.i(LOG_TAG, "DataMap received on watch: " + dataMap);

                    // Get the data map items
                    String sunshine_temperature_high = dataMap.getString("sunshine_temperature_high");
                    String sunshine_temperature_low = dataMap.getString("sunshine_temperature_low");

                    // Create the intent
                    Intent send_weather = new Intent("ACTION_WEATHER_CHANGED");
                    send_weather.putExtra("sunshine_temperature_high", sunshine_temperature_high);
                    send_weather.putExtra("sunshine_temperature_low", sunshine_temperature_low);
                    // Broadcast it
                    sendBroadcast(send_weather);

                }
                else if (event.getType() == DataEvent.TYPE_DELETED) {
                    // DataItem deleted
                }
   }

在GitHub上向您发送了一个带有更正的拉取请求。 好像你只是忘了连接你的谷歌客户端:))

mGoogleApiClient.connect();

您的代码中的一些额外的小变化(一些重构)。

您是否将CanvasWatchFaceService添加为数据更改事件的侦听器?在onConnected中,请确保您致电:

Wearable.DataApi.addListener(mGoogleApiClient, this);

你应该经常检查:

  1. 您的手机已连接至磨损
  2. 包名称相同
  3. 您在两个应用中使用相同的Google Play服务版本
  4. 您正在使用相同的密钥库签署移动和磨损应用
  5. 我被GoUbiquitous困住了10天,直到找到最后一个: - \
