1*d353a188SXin LiAndroid ContentProviderPaging Sample (Kotlin) 2*d353a188SXin Li=================================== 3*d353a188SXin Li 4*d353a188SXin LiThis sample demonstrates how to use the ContentProvider with paging support introduced 5*d353a188SXin Liin Android O. The ContentProvider now accepts additional arguments for the offset and 6*d353a188SXin Lithe limit in the query method to support paging instead of fetching all the data in 7*d353a188SXin Lia single query method call. 8*d353a188SXin Li 9*d353a188SXin LiIntroduction 10*d353a188SXin Li------------ 11*d353a188SXin Li 12*d353a188SXin Li[ContentProvider][1] and [DocumentsProvider][2] now supports paging instead of fetching the all 13*d353a188SXin Lidata at once. 14*d353a188SXin Li 15*d353a188SXin LiStarting from Android O, ContentProvider#query(Uri, String[], Bundle, CancellationSignal) and 16*d353a188SXin LiDocumentsProvider#query(Uri, String[], Bundle, CancellationSignal) methods are introduced. 17*d353a188SXin LiThe Bundle accepts the keys for ContentResolver.QUERY_ARG_OFFSET as an starting offset and 18*d353a188SXin LiContentResolver.QUERY_ARG_LIMIT as the number of items included in the returned Cursor object. 19*d353a188SXin Li 20*d353a188SXin LiSimilarly, the returned Cursor object now has a Bundle object obtained by Cursor#getExtras(). 21*d353a188SXin LiThe Bundle is able to include data such as the total size of the underlying data set. 22*d353a188SXin Li 23*d353a188SXin Li[1]: https://developer.android.com/reference/android/content/ContentProvider.html 24*d353a188SXin Li[2]: https://developer.android.com/reference/android/provider/DocumentsProvider.html 25*d353a188SXin Li 26*d353a188SXin LiPre-requisites 27*d353a188SXin Li-------------- 28*d353a188SXin Li 29*d353a188SXin Li- Android SDK 25 30*d353a188SXin Li- Android Build Tools v25.0.3 31*d353a188SXin Li- Android Support Repository 32*d353a188SXin Li 33*d353a188SXin LiScreenshots 34*d353a188SXin Li------------- 35*d353a188SXin Li 36*d353a188SXin Li<img src="screenshots/screenshot-1.png" height="400" alt="Screenshot"/> 37*d353a188SXin Li 38*d353a188SXin LiGetting Started 39*d353a188SXin Li--------------- 40*d353a188SXin Li 41*d353a188SXin LiThis sample uses the Gradle build system.
