The data type defines the schema for a stream of data being collected by or queried from the Recording API on mobile. The data type defines only the representation and format of the data, and not how it's being collected, the sensor being used, or the parameters of the collection.
A data type containsLocalFields.
The field defines the format of the data (such as int or float).
Data types can be aggregates, and can be computed as part of read requests by calling
LocalDataReadRequest.Builder.aggregate(LocalDataType).

Inherited Method Summary
Fields
public static final LocalDataType TYPE_CALORIES_EXPENDED
In thecom.google.calories.expendeddata type, each data point
represents the number of calories expended, in kcal, over the time interval of the data
point. The field value is stored as a float. Note: this total calories number includes
BMR calories expended.
Start and end times should be set to denote the duration over which the calories were expended.
From API level 29, recording data of this type requires the
ACTIVITY_RECOGNITIONruntime permission.
public static final LocalDataType TYPE_DISTANCE_DELTA
In thecom.google.distance.deltadata type, each data point represents
the distance covered, in meters,since the last reading.The total
distance over an interval can be calculated by adding together all the values during
the interval.
The start time of each data point should represent the start of the interval in which the distance was covered. The start time must be equal to or greater than the end time of the previous data point.
Registering to, or subscribing to data of this type requires
Manifest.permission.ACCESS_FINE_LOCATION.
From API level 29, recording data of this type requires the
ACTIVITY_RECOGNITIONruntime permission.
public static final LocalDataType TYPE_STEP_COUNT_DELTA
In thecom.google.step_count.deltadata type, each data point
represents the number of steps takensince the last reading.When
using this data type, each step is only ever reported once, in the reading immediately
succeeding the step. By adding all of the values together for a period of time, the
total number of steps during that period can be computed.
As an example, if a user walked a total of 5 steps, with 3 different readings, the values for each reading might be [1, 2, 2].
The start time of each data point should represent the start of the interval in which steps were taken. The start time must be equal to or greater than the end time of the previous data point.
From API level 29, recording data of this type requires the
ACTIVITY_RECOGNITIONruntime permission.
