Read weight from google fit

问题

I can't read a weight from Google Fit. When I make request to Google Fit for weight I get only name of weight field (weight) but DataPoints size is 0. What is wrong?

code:

DataReadRequest dataReadRequest = queryFitnessData();

DataReadResult dataReadResult = Fitness.HistoryApi.readData(getApiClient(), dataReadRequest)
                .await(1000, TimeUnit.MILLISECONDS);
////////
private static DataReadRequest queryFitnessData() {
    Calendar calendar = Calendar.getInstance();
    Date date = new Date();
    calendar.setTime(date);
    long endTime = calendar.getTimeInMillis();
    calendar.add(Calendar.YEAR, -1);
    long startTime = calendar.getTimeInMillis();

    DataReadRequest dataReadRequest = new DataReadRequest.Builder()
            .read(DataType.TYPE_WEIGHT)
            .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
            .build();

    return dataReadRequest;
}

Do you have weight added in the timerange you specified.Can you try

DataReadRequest dataReadRequest = new DataReadRequest.Builder()
            .read(DataType.TYPE_WEIGHT)
            .setTimeRange(1, endTime, TimeUnit.MILLISECONDS)
            .setLimit(1)
            .build();
