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.

[ContentProvider][1] and [DocumentsProvider][2] now supports paging instead of fetching the all
|
|
data at once.
|
|
|
|
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.
