How to Obfuscate java code - android

In my android application, i want to generate a random number which follows some rules. I write that method in a class and I don't want the users to see my formula. I am obfuscating my application, but some how by reverse engineering, we can see the methods and classes. How to prevent that class from getting reverse engineered. Once it is obfuscated even i also don't want to open those file. I just call that method from my application.

Use the Android NDK, put the calculation in a native library and call it through JNI. You'll have to compile your native code for all the targeted architectures, which shouldn't be a problem if your code already runs in Java.

I think you should research Polymorphic code. This is different from Polymorphism in type theory. This stack overflow post should also help.

Best practice would be to have that calculation done server-side and sent to the client.

Otherwise, it is nearly impossible (mathematically speaking) to prevent reverse engineering no matter what.
