Answer 1

The problem was with room. The schema export directory was not set. Build log feint me as the error appeared on the bottom of the log.

reference to real issue - room-schema-export

Answer 2

Create a call like

@GlideModule
public final class GlideLoader extends AppGlideModule{


 }

And Build Project.Then You will access glide by GlideApp.
