I make mobile application , Am really a Programmer

Rather than just copy/paste, study the code and try to understand how the author is doing what he's doing. I study other people's code all the time in order to learn new concepts. Then, you can use what you learned and expand on it in the future. I would also try to apply the concepts you learned from the samples and rewrite the code yourself.

coding is a very small part of programming. your next level is to plan before you code. have a blue print of what you are going to do, put it down on paper. learn UML and create your diagrams. this forces you to think through what you are trying to do. then it's just a matter of translating what you're thinking into code. you'll find yourself creating code.

All coding is essentially copying and pasting (whether literally or figuratively from memory).
