Proguard RoboGuice Obfuscate Error on ViewListener

Question

I have proguard and roboguice working together as long as I don't turn on the obfuscate option. Once I remove dontobfuscate from my progaurd-project.txt file, I receive the following error:

NullPointerException:
roboguice.inject.ViewListener$ViewMembersInjector.reallyInjectMemberViews (SourceFile:172)
roboguice.inject.ViewListener$ViewMembersInjector.reallyInjectMembers (SourceFile:138)
roboguice.inject.ViewListener$ViewMembersInjector.injectViews (SourceFile:246)
roboguice.inject.ContextScopedRoboInjector.injectViewMembers (SourceFile:270)
roboguice.fragment.RoboFragment.onViewCreated (SourceFile:19)

Does anyone have any ideas on how to fix that error? Here is my configuration file

Answer 1

I'm not a proguard expert, but it looks like it is still obfuscating the roboguice library even though you have it included in the -libraryjars section. You could try to exclude it via its package.

-keep class roboguice.** { *; }
