DataClient.OnDataChangedListener

  • DataClient.OnDataChangedListener is an interface used to receive data events on Android Wear devices.

  • It is used with DataClient.addListener() to register for data change notifications.

  • The onDataChanged() method is triggered when data items are changed or deleted, providing a DataEventBuffer containing information about the changes.

  • For persistent usage outside the callback, DataEvent objects within the buffer should be frozen.
