Android: Java: Proguard: How to: verify if my jar (different jar project)/apk are successfully processed? (I am thinking to reverse engineer it)

I successfully processed my jar and apk. Then, want to verify if is it truly hard to reverse engineer or truly did the obfuscation.

I am thinking to try to reverse engineer it by myself to see what I did. But don't know开发者_JAVA百科 how to do it.

For manual reverse engineering, you can try dex2jar and then Java Decompiler.

I assume you have a set of tests (unit/functionality). Run them against the obfuscated jar file. They should pass as if you had the original program.
