I just changed:
xmlns:app="http://schemas.android.com/apk/res-auto"
to:
xmlns:app="http://schemas.android.com/apk/lib/com.app.chasebank"
and it stopped generating the errors, com.app.chasebank is the name of the package. It should work according to this Stack Overflow : No resource identifier found for attribute ‘adSize’ in package ‘com.google.example’ main.xml
