Read Aggregate Daily Nutrition Data

This section demonstrates reading the aggregate daily nutrition from a specific data source. The response contains a list of buckets (one per 24-hour period), each with a single dataset and datapoint that contains a field for all recorded nutrition data types. If no nutrition values exist for a particular time period, there is no dataset. If more than one meal_type is recorded, the value will be set to UNKNOWN.


Your app can read the aggregate daily nutrition data for a user by creating a data read request, and specifying the aggregate for the DataType.TYPE_NUTRITION and DataType.AGGREGATE_NUTRITION_SUMMARY data types, as shown in the following example:

DataReadRequest readRequest = new DataReadRequest.Builder()
    .bucketByTime(1, TimeUnit.DAYS)
    .setTimeRange(<start time>, <end time>, TimeUnit.MILLISECONDS)


Your app can read the aggregate daily nutrition data for a user by making a POST request and querying the specified data source. You must make a separate query for each data source.
