How safe is my soucecode in my APK?

Question

I was wondering how safe my source code is in my APK? By this I mean. If i give my apk to someone, could he see my sourcecode or could he extract, unzip, decompile the APK? With or without extra programs?

Or is this not possible?

Why downvote? Isn't this a good question? ifnot what should I have typed? — Koen Van Looveren, Dec 19 '15 at 10:29

Basically a user can try to decompile and see the source code and its possible to decompile a apk. But, it will take time to decompile and understand this code. So, to prevent this you can use Proguard to prevent it from understanding the code.

Oke :D indeed this is what I need, and if you decompile the proguarded version what do you see? bytecode? or just encrypted code. an – Koen Van Looveren Dec 19 '15 at 10:33

Its encrypted code like it will convert the class names to random names like A,B,....Z which is very difficult to understand. – Nigam Patro Dec 19 '15 at 10:35

so if you decompile it will look like this -> http://1.bp.blogspot.com/-S4jYYohH6fw/Uooe7KDPImI/AAAAAAAAEpQ/1y31P2BSgvY/s1600/obfuscate02.png – Koen Van Looveren Dec 19 '15 at 10:37
