No resource identifier found for attribute '…' in package 'com.app…'

Question

I\'ve imported a project from Eclipse to Android studio. It utilizes a custom view:

xmlns:app="http://schemas.android.com/apk/res-auto"

Answer 1

I solved is by using android:background instead of app:srcCompact.

This is caused by xmlns:app="http://schemas.android.com/apk/res-auto". As people have suggested above, you could use /lib-auto or /lib/your-package but I got suspicious namespace error when I tried using /lib-auto and unexpected namespace prefix error with /lib/my-package .
