Android hide the implementation of class?

Question

I am new to android development and need some solution for this problem, I have created a class that does some encryption work and have to give that to another person but I can't let them know the implementation of this class, so what i've done is encapsulated the methods..

I read that Creating a jar library is for a complete application.. since i need to give only a single file i can't make a jar library.. any solution for this???

Any help would be great.. thanks in advance..

Answer 1

compile your file, create a .class file and give it to them. But before giving take care of following things

1. java version.
2. supporting library required.
