My problem is that I need to access my LayoutNameBinding, but I am unable to do so. Only DataBinding generated class which is available is LayoutNameBindingImpl.
- Build is successful (No errors)
- DataBinding is enabled within build.gradle(:app)
- DataBinding plugin kotlin-apt is applied within build.gradle(:app)
- My layout is contained within a
<layout> - LobbyFragmentBinding.java is generated and contains LobbyFragmentBinding
The commented part is what I would like to be able to do within my code. Part of the code shown is inspired of https://github.com/android/sunflower which explains how to use different parts of Android JetPack.
Solutions tried
- Rebuild
- Manually add "import com.kotlin.projet3.databinding.LobbyFragmentBinding"
- Solutions found at android: data binding error: cannot find symbol class (Problem is not the same, but tried anyways)
- Solutions found at Data Binding class not generated (Problem is not the same, but tried anyways)
