Even if the application is reverse engineered and say an cracker gets 100% of your code. Still, what is use? it is your app that is first in android market in case of android market apps. If someone makes a clone, it is still a 'clone' and you are the original. We are using Java and hence risk of code stealing would always be there for us. May developing in C may help, but again it has its own complications.
