This sample demonstrates how to use the ContentProvider with paging support introduced in Android O. The ContentProvider now accepts additional arguments for the offset and the limit in the query method to support paging instead of fetching all the data in a single query method call.
Starting from Android O, ContentProvider#query(Uri, String, Bundle, CancellationSignal) and DocumentsProvider#query(Uri, String, Bundle, CancellationSignal) methods are introduced. The Bundle accepts the keys for ContentResolver.QUERY_ARG_OFFSET as an starting offset and ContentResolver.QUERY_ARG_LIMIT as the number of items included in the returned Cursor object.
Similarly, the returned Cursor object now has a Bundle object obtained by Cursor#getExtras(). The Bundle is able to include data such as the total size of the underlying data set.
This sample uses the Gradle build system. To build this project, use the "gradlew build" command or use "Import Project" in Android Studio.
