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
.
Android
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:
val readRequest = DataReadRequest.Builder()
.aggregate(DataType.AGGREGATE_NUTRITION_SUMMARY)
.bucketByTime(1, TimeUnit.DAYS)
.setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
.build()
REST
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.
