I am getting this error:
FATAL EXCEPTION: main
Process: com.example.app, PID: 2902
java.lang.IllegalStateException: Could not find method showSublayersDialog(View) in a parent or ancestor Context for android:onClick attribute defined on view class androidx.appcompat.widget.AppCompatImageButton with id 'ellipsisButton'
I've added an ellipsis button to the front of my app to control sub layer visibility and to change map style. Everything worked great until I tried implementing the map style buttons. Any help would be appreciated.
Here is my MainActivity
