I guess it is the same error like in #10 #11 #12 #13
But i don't know if you need more "errors" to bring out a fix.

hi guy,

your dex is protected under some protector.

Please get the real dex on runtime and then try it with dex2jar.

Yes the protector being used is ProGuard. I just could not efford the time to have a look into it with IDA Pro.
I can't get the apk without ProGuard since it is not my application.
I just could see how you can upgrade your app protection with those pdfs you wrote.

What do you mean exactly by getting the real dex on runtime?

[pxb1988]

as i known, proguard is a just an obfuscator, rename ids, optimize code. it does not encrypt code.

the dex is modified by a protector, the code is encrypted, and decrypt on runtime. so try get the decrypted dex (the real dex) on runtime
