In an Android project, when an activity extends an AA-generated "_" class, AA cannot correctly traverse the complete supertypes line, causing problems in certain cases.

Example:

@EActivity(R.layout.hello_world)
public class HelloWorldActivity extends BaseActivity_ 

Where BaseActivity_ has been generated by AA from BaseActivity.

The Javadoc of AnnotationHelper.isSubtype mentions this issue. Basically the problem is that the generated "_" sources don't exist yet at the time we want to traverse the supertypes, cutting off the traversal.

This limitation is an issue for SherlockHelper.usesSherlock where determining the correct supertype of a given activity is vital in generating the correct source. The attempt of AnnotationHelper.isSubtype is unfortunately not good enough for the specific case of SherlockHelper.usesSherlock, where a definite supertype must be determined.

The solutions to this problem are either generating the sources in rounds to make sure that needed generated classes are existent (from aforementioned Javadoc), or somehow skipping BaseActivity_ in the example above to continue the traversal from BaseActivity.
