Java SecurityException: signer information does not match

Question

I recompiled my classes as usual, and suddenly got the following error message. Why? How can I fix it?

java.lang.SecurityException: class \"Chinese_English_D         


        

Answer 1

In my case it was a package name conflict. Current project and signed referenced library had one package in common package.foo.utils. Just changed the current project error-prone package name to something else.
