Hello sahil,

As of now as you are in class 11th so I would recommend that your major focus should be in your academics and you can do the research on this as a part time on weekends. 11th standard forms the crux of your future atleast till entrance examinations.

So, if you have taken computer science in your 11th std. then kindly focus on programming language which is been taught in school. Then you can start learning python then practice programming in platforms like hackerearth, code chef and a few more. You can practice from any one.

You can also study courses on app development from Coursera an udemy.
