问题:

I am using Google Fit Api in my project to get user's daily steps. But the problem is, user can enter the steps manually by adding the activities. And when i retrieve the daily steps, Google Fit Api also returns the steps which were added manually. Is there any way to differentiate between manually added steps and sensor recorded steps.

This is how i solved this issue.

   final DataReadRequest readRequest = new DataReadRequest.Builder()
            .read(googleFitUtils.getEstimatedSteps())
            .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
            .build();

    DataReadResult dataReadResult =
            Fitness.HistoryApi.readData(mGoogleApiFitnessClient, readRequest).await(1, TimeUnit.MINUTES);

    DataSet stepData = dataReadResult.getDataSet(DataType.TYPE_STEP_COUNT_DELTA);

    int totalSteps = 0;

    for (DataPoint dp : stepData.getDataPoints()) {
        for(Field field : dp.getDataType().getFields()) {
            int steps = dp.getValue(field).asInt();
            if (!"user_input".equals(dp.getOriginalDataSource().getStreamName()))
                totalSteps += steps;
        }
    }

First Point - > Before i was getting the total steps using

Fitness.HistoryApi.readDailyTotal

which returns one data point with total daily steps. Second Point - > Then i changed the way to get the daily steps using

Fitness.HistoryApi.readData

It returns array of data points with the chunks of daily steps. Each data point has a property of

dp.getOriginalDataSource().getStreamName()

which returns you the type, either steps were recorded by sensor or it was a use input. That's how you can filter the user input steps to avoid steps hack in your application.
