App crashes in release mode only, how to configure proguard?

Question

My app crashes in release mode only, due to proguard (confirmed, I disabled it and worked)... I see somebody had the same problem and tried some solutions like this one: Android: app crashed when starting after signing in release mode .

I first tried keeping the MainActivity, then tried keeping the whole package with

-keep class android.app.**

but it still doesn't solve. Logcat in this case is nearly useless due to obfuscation, proguard is kind of complex to understand, also because I don't find clues on which part I should tune.

Do you have any idea on how I should configure proguard?

Do you use third party libraries? If you do, check their dedicated pages to see if one of them needs some Proguard rules — Gorcyn, Feb 24 '15 at 16:56
If you have the mapping.txt file from your proguard build you can de-obfuscate the stacktrace using retrace in the android SDK — dymmeh, Feb 24 '15 at 16:58

You didn't literally use `-keep class android.app.**`, right? — tachyonflux, Feb 24 '15 at 17:01
That was a third party library indeed! Thank you @Gorcyn, add the answer below if you want me to accept. — glass, Feb 24 '15 at 17:07

Common problems with that is using third party libs. Check your dependency and exclude those libraries from obfuscation process.
