Proguard: Android Studio: cannot find symbol class ErrorListener, Method, ImageCache

I am new to Proguard and I was implementing it in my application

App->Module1->ApIManager->Volley is the dependency diagram

I am using Grale. Without Proguard everything runs fine. However with Proguard I get the error above on three class uses.

I notices that all of these are under com.android.volley and are interfaces

My Proguard.cfg for APImanager and volley is

Code runs fine without proguard, I have tried almost everything and went through a lot of tutorials too without help.
