未收到來自Google Fit的實時計步器更新

Question

我想通過檢查他們的步數增量是否大於0來檢查是否有人正在使用Google Fit API。這似乎比使用歷史API獲取每日步數更簡單弄清楚它是否從前面的查詢中增加。

我跟着代碼here，但代替位置跟蹤，我做delta步計數。但是，聽衆似乎沒有檢索到最新的增量步數。

這裏是我的代碼：

public void buildFitnessClient() 
{ 
    if (mClient == null && checkPermissions()) 
    { 
     mClient = new GoogleApiClient.Builder(this) 
       .addApi(Fitness.SENSORS_API) 
       .addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ)) 
       .addConnectionCallbacks(
         new GoogleApiClient.ConnectionCallbacks() 
         { 
          @Override 
          public void onConnected(Bundle bundle) 
          { 
           Log.d(TAG, "Connected!!!"); 
           // Now you can make calls to the Fitness APIs. 
           findFitnessDataSources(); 
          } 

          @Override 
          public void onConnectionSuspended(int i) 
          { 
           // If your connection to the sensor gets lost at some point, 
           // you'll be able to determine the reason and react to it here. 
           if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) 
            Log.d(TAG, "Connection lost. Cause: Network Lost."); 
           else if (i 
             == GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) 
            Log.d(TAG, "Connection lost. Reason: Service Disconnected"); 
          } 
         } 
       ) 
       .enableAutoManage(this, 0, new GoogleApiClient.OnConnectionFailedListener() 
       { 
        @Override 
        public void onConnectionFailed(ConnectionResult result) 
        { 
         Log.d(TAG, "Google Play services connection failed. Cause: " + 
           result.toString()); 
        } 
       }) 
       .build(); 
    } 
} 

private void findFitnessDataSources() 
{ 
    // Note: Fitness.SensorsApi.findDataSources() requires the ACCESS_FINE_LOCATION permission. 
    Fitness.SensorsApi.findDataSources(mClient, new DataSourcesRequest.Builder() 
      // At least one datatype must be specified. 
      .setDataTypes(DataType.TYPE_STEP_COUNT_DELTA) 
      // Can specify whether data type is raw or derived. 
      .setDataSourceTypes(DataSource.TYPE_DERIVED) 
      .build()) 
      .setResultCallback(new ResultCallback<DataSourcesResult>() 
      { 
       @Override 
       public void onResult(DataSourcesResult dataSourcesResult) 
       { 
        Log.d(TAG, "Result: " + dataSourcesResult.getStatus().toString()); 
        for (DataSource dataSource : dataSourcesResult.getDataSources()) 
        { 
         Log.d(TAG, "Data source found: " + dataSource.toString()); 
         Log.d(TAG, "Data Source type: " + dataSource.getDataType().getName()); 

         //Let's register a listener to receive Activity data! 
         if (dataSource.getDataType().equals(DataType.TYPE_STEP_COUNT_DELTA) 
           && mListener == null) 
         { 
          Log.d(TAG, "Data source for STEP_COUNT_DELTA found! Registering."); 
          registerFitnessDataListener(dataSource, 
            DataType.TYPE_STEP_COUNT_DELTA); 
         } 
        } 
       } 
      }); 
} 

private void registerFitnessDataListener(DataSource dataSource, DataType typeStep) 
{ 
    mListener = new OnDataPointListener() 
    { 
     @Override 
     public void onDataPoint(DataPoint dataPoint) 
     { 
      Log.d(TAG, "Detected onDataPoint"); 
      for (Field field : dataPoint.getDataType().getFields()) 
      { 
       Value val = dataPoint.getValue(field); 
       Log.d(TAG, "Detected DataPoint field: " + field.getName()); 
       Log.d(TAG, "Detected DataPoint value stepCount: " + val); 
       TransientValues.setStepCountDelta(val.asInt()); 
      } 
     } 
    }; 


    Fitness.SensorsApi.add(
      mClient, 
      new SensorRequest.Builder() 
        .setDataSource(dataSource) // Optional but recommended for custom data sets. 
        .setDataType(typeStep) // Can't be omitted. 
        .setSamplingRate(1L, TimeUnit.SECONDS) 
        .build(), 
      mListener) 
      .setResultCallback(new ResultCallback<Status>() 
      { 
       @Override 
       public void onResult(Status status) 
       { 
        if (status.isSuccess()) Log.d(TAG, "Listener registered!"); 
        else Log.d(TAG, "Listener not registered."); 
       } 
      }); 
} 

的onDataPoint方法不mListener = onDataPointListener(){...} -> registerFitnessDataListener(...)叫，我不知道爲什麼。通過實施這類

implements OnDataPointListener

嘗試我有同樣的問題，這個固定。讓我知道它是否有幫助。
