Getting following error when I try to exclude 3rd party libraries in the ProGuard.

It is compiling, if i add "-dontwarn com.ak.systemservice.core.security.FuncManager" in the proguard-project.txt,
but getting crash when try to run.

Basically I want to NOT to obfuscate "com.ak.systemservice. core.security.FuncManager" class in jar or entire jar, and want to use "com.ak.systemservice. core.security.FuncManager"in my activity. Thanks in advance.

Here are the errors:
