Request for Reading Data

Mandatory information	Description
Data type	Set the data type with: ReadRequest.Builder.setDataType()

You can make a request instance with ReadRequest.Builder.build().

Reading Data Example

You can read Samsung Health's health data with HealthDataResolver.read().

 // The state of connection
 private final HealthDataStore mStore;

 public static final String APP_TAG = "MyApp";
 private static final long ONE_DAY_IN_MILLIS = 24 * 60 * 60 * 1000L;

     today.set(Calendar.SECOND, 0);
     today.set(Calendar.MILLISECOND, 0);

     return today.getTimeInMillis();
 }

 private void readTodayStepCount() {
     // Set time range from start time of today to the current time
     long startTime = getStartTimeOfToday();
