      For reading and writing historical fitness data, use Health Connect
      instead.
Client for reading fitness Goals created
      by users in Google Fit.
The 
      readCurrentGoals(GoalsReadRequest) method should be used whenever goals are
      needed.
The Goals Client should be accessed via the Fitness entry
      point. Example:
    GoogleSignInOptionsExtension fitnessOptions =
        FitnessOptions.builder()
            .addDataType(DataType.TYPE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_READ)
            .addDataType(DataType.TYPE_DISTANCE_DELTA, FitnessOptions.ACCESS_READ)
            .build();
    GoogleSignInAccount googleSignInAccount =
        GoogleSignIn.getAccountForExtension(this, fitnessOptions);
    Task<List<Goal>> response = Fitness.getGoalsClient(this, googleSignInAccount)
        .readCurrentGoals(new GoalsReadRequest.Builder()
            .addDataType(DataType.TYPE_STEP_COUNT_DELTA)
            .addDataType(DataType.TYPE_DISTANCE_DELTA)
            .build());
    List<Goal> goals = Tasks.await(response);
 This Client can be combined with a subscription in the Recording
      Client to collect goal progress data in the background and query it later for
      displaying. A simple progress query example for a step metric goal:
    Calendar current = Calendar.getInstance();
    Task<DataReadResponse> response = Fitness.getHistoryClient(this, googleSignInAccount)
        .readData(new DataReadRequest.Builder()
            .read(DataType.TYPE_STEP_COUNT_DELTA)
            .setTimeRange(
                goal.getStartTime(current, TimeUnit.NANOSECONDS),
                goal.getEndTime(current, TimeUnit.NANOSECONDS),
                TimeUnit.NANOSECONDS)
            .build());
    DataReadResponse stepReadResponse = Tasks.await(response);
    List<DataPoint> dataPoints =
        stepReadResponse.getDataSet(DataType.TYPE_STEP_COUNT_DELTA).getDataPoints();
    int total = 0;
    for (DataPoint dataPoint : dataPoints) {
      total += dataPoint.getValues()[0].asInt();
    }
    double progress = total / goal.getMetricObjective().getValue();
