Android proguard, keep inner class

Question

My android program has a class A, which has two static inner class. They are found to be stripped from .dex after applying proguard.

Answer 1

Your configuration looks correct. You should double-check that you haven't misspelled the class names. If the spelling in incorrect, ProGuard should print out a note about it. You can also specify -printseeds seeds.txt, and see if your classes are listed in the resulting file. If they are listed, the classes are also in the processed code.

As Alexander Lucas mentioned, you may also want to keep the fields and methods of these classes -- that depends on your requirements.
