Android : Class file collision: A resource exists with a different case

If you are getting such kind of error in one of your Java Classes in your Android Project folder, then its because you might have had a class with the same name but having difference case, to resolve this issue,

1. Go to Window → Show view → Navigator
2. Now you should be able to see classes folder in your Project Navigator view at the left.
3. Just delete the classes folder.
4. Do a Clean + Build.
5. The error must go
6. You may also try to delete the gen folder, but that didn't work for me.
