Don't wrap activities. Wrap the features that you need and add them to your activity.

Which library are you trying to wrap?

the actual activity_main layout id in r.java is 0x7f0b001c.
but in BA.applicationContext.getResources().getIdentifier("activity_main", "layout", BA.packageName) I got the 0x7f040000

The problem is with the R.java file. Now can start Activity from libarary normal.
