java - 在 Android Wear 上阅读每日步数

Question

我正在尝试用一些信息写一个表盘。现在我想阅读每日步数...

我试过这段代码：

        Calendar start;

        start = Calendar.getInstance();
        start.setTimeInMillis(System.currentTimeMillis());
        start.set(Calendar.MILLISECOND, 0);
        start.set(Calendar.SECOND, 0);
        start.set(Calendar.MINUTE, 0);
        start.set(Calendar.HOUR_OF_DAY, 0);

        try
        {
          GoogleSignInOptionsExtension fitnessOptions =
                  FitnessOptions.builder()
                          .addDataType(DataType.TYPE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_READ)
                          .build();

          GoogleSignInAccount googleSignInAccount =
                  GoogleSignIn.getAccountForExtension(getApplicationContext(), fitnessOptions);

          Task<DataReadResponse> response = Fitness.getHistoryClient(getApplicationContext(), googleSignInAccount)
                  .readData(new DataReadRequest.Builder()
                          .read(DataType.TYPE_STEP_COUNT_DELTA)
                          .setTimeRange(start.getTimeInMillis(), System.currentTimeMillis(), TimeUnit.MILLISECONDS)
                          .build());

          DataReadResponse readDataResult = Tasks.await(response);
          DataSet dataSet = readDataResult.getDataSet(DataType.TYPE_STEP_COUNT_DELTA);
          total = dataSet.isEmpty()
                  ? 0
                  : dataSet.getDataPoints().get(0).getValue(Field.FIELD_STEPS).asInt();
        }
        catch(ExecutionException e)
        {
          e.printStackTrace();
        }
        catch(InterruptedException e)
        {
          e.printStackTrace();
        }

编译时没有错误，没有关于模拟器的信息，但是当我尝试在我的 SmartWatch 上运行它时，我得到了这个异常：

第 284 行是 DataReadResponse readDataResult = Tasks.await(response);
为什么 Fitness.CLIENT 不可用？我怎样才能使它可用？
我真的不知道我能做些什么来获得日常步骤......我为此目的找到了许多代码示例，但没有任何效果......

有人能帮我吗？

非常感
