In the course https://codelabs.developers.google.com/codelabs/mdc-103-java#2 there is the instruction Set the android:tint attribute on the logo <ImageView> in shr_login_fragment.xml to ?android:attr/textColorPrimary.... but Android Studio highlights this code as an error and suggests using app:tint instead of android:tint
