thanks first of all. But I know this. You know most of answers in this post is like that. Try to solve the problem. I know this you know this everybody know this. But the thing is that we do not get problems or we get that are already solved in some form till now. Do not get me wrong. But really I think what to do. What is require which other people have and I do not have. When I saw on github or appstore doing things by other people I feel I can do this and I should do this. But when I try to do that I do not know where to start. You know why because I do not know what to start. I do not want to do which other people alerady done. They are doing something unique and I also want to do that. But do not know what. If any body please help I really appreciate. BTW thanks a lot for your answer.
