Component used: room, rxjava, guava, paging

Version used: room - 2.4.0-alpha-02 (is present in 2.3.0 too) paging - 3.0.0

Devices/Android versions reproduced on: Project didn't compile. It's an compilation issue

Room Dao isn't able to return RxPagingSource or ListenableFuturePagingSource

I have attached small sample project. You can observe the issue when you build this project

It will give error in sampleDao_impl.java

incompatible types: PagingSource<Integer,String> cannot be converted to RxPagingSource<Integer,String>

Note :- This does not occur when you remove abstract getDAO method from db class which extends RoomDatabase. In the given project file if you remove @line 25 public abstarct sampleDao getSampleDAO() from db.java the issue will not occur
