In order to define the pivot in an XML-instanciated RotateDrawable, android:pivotX and android:pivotY had to be set in your XML. Forgetting to set those attributes ended up in a NullPointerException (tv = null) that were caught by the Resources.getDrawable() method (caught as an Exception). As a result a not-very-accurate message was logged: "Resource not found ...". Defining a default pivot value seems like a great fix. Some other fixes would be to modify the documentation or notify the user with a better explanation than "Resource not found ...".
