Google fit fetch last record

Question

Is it possible to fetch only last record from Google Fit ? Not timerange, but just one entry from data set. I need to find time when that record is written.

Let's say I have to sync data from my app with Google Fit. I need to know when the last updated record is synced so I could find all values that are newer and not synced yet. I can save timestamp in local database, but I think that this is cleaner.

Thanks!

Use the setLimit(int limit) method on the DataReadRequest.Builder.

like so:

long monthInMillis = 2592000000; // It can be a year or more if you want.. Any way you are limiting the result to 1 DataPoint.
long endTime = new Date().getTime(); // Now
long startTime = endTime - monthInMillis;

DataReadRequest.Builder builder = new DataReadRequest.Builder();
builder.read(dataType);
builder.setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS);
builder.setLimit(1); // This will get the latest record for the dataType
DataReadRequest readRequest = builder.build(); 

mHistoryClient.readData(readRequest)
.addOnSuccessListener(new OnSuccessListener<DataReadResponse>() {
    @Override
    public void onSuccess(DataReadResponse dataReadResponse) {

        for (DataSet dataSet : dataReadResponse.getDataSets()) {
            for (DataPoint dataPoint : dataSet.getDataPoints()) {
                if (dataPoint.getDataType().getName().equals(DataType.TYPE_LOCATION_SAMPLE.getName())) {
                    // Location DataPoint
                    long startTime = dataPoint.getStartTime(TimeUnit.MILLISECONDS);
                }

                if (dataPoint.getDataType().getName().equals(DataType.TYPE_ACTIVITY_SEGMENT.getName())) {
                    // Activity DataPoint
                    long endTime = dataPoint.getEndTime(TimeUnit.MILLISECONDS);
                }

                if (dataPoint.getDataType().getName().equals(DataType.TYPE_STEP_COUNT_DELTA.getName())) {
                    // Steps DataPoint
                }
            }
        }
    }
});

public DataReadRequest.Builder setLimit (int limit)

Limits results to the latest limit data points. This parameter is ignored for aggregated queries. By default there is no limit.
