When an application defines themes that are not inherited from
android:style/Theme, it may cause UnsupportedOperationException.
The cause is that the attributes needed by the application are
defined in neither theme nor layout attribute set.
It takes really a long time to trace all of the themes applied.
This patch logs the basic information about themes to help the
developers to triage issues.
