I develop Android app and some of the codes are very private and confidential. I make encryption algorithm into my code to increase the safety.
But recently I read, when people having an .apk file, they can extract the java source code with 100% correct Source.
Not just that, people also can get .apk from Google Play Store Source
Does it means people who has my .apk can view all my source code(java, .xml layout, library)? If yes, all my hard work to have a secure app is not achieved.
