Hi, I would recommend that you set up an offshore company as the app's main developer, if i remembered correctly, the mda does not approve of such apps. btw, you dont have to worry about open sourcing your app as anyone can simply decompile it with apktool. ;)
I second this. Decompiling java to bytecode is not only easy, but not very hard to read with a bit of experience. It's like reading normal java code but slightly more concise haha. However, I can understand the developer's concern. I think the best way to go about is to put in copyright notices and some sort of license on it. Then, go for the lawsuit if you really need/want to.
