android - What's the difference between ContentObservable and DataSetObservable? -
they both inherit observable. , functions not differ much, why not provide single class?
as can see code sources, datasetobservable sending notifications list of datasetobserver objects, while contentobservable sending notifications list of contentobserver objects
see sources: https://github.com/android/platform_frameworks_base/blob/master/core/java/android/database/datasetobservable.java
