Structure:
1) a Super class child of AppCompactActivity which implements a public void clickedOnButton(View v) {...} method
2) a Subclass which doesn't implement the clickedOnButton method
3) a layout xml file which uses  tools:context="package.subclass"
4) a button which uses android:onclick.

Method Autocomplete works in both Design and Text view modes and let select clickedOnButton method but both modes reports an error: "Corresponding method handler -method signature- not found".

Editor isn't able to detect public methods inherited (while autocomplete works)

Only temp fix is to override parent method to avoid error reporting on layout file.

Note: Project complies and run without problems.
