32 * LiveData is a data holder class that can be observed within a given lifecycle.
43 * activities and fragments where they can safely observe LiveData and not worry about leaks:
47 * In addition, LiveData has {@link LiveData#onActive()} and {@link LiveData#onInactive()} methods
49 * This allows LiveData to release any heavy resources when it does not have any Observers that
