I Agree with Gonzoox, learning any programming language & technology is not that easy and requires dedication and commitment. To start with; the way you develop winform application a bit different than building a web application, both have different life cycles which has to be understood also android also has its own life cycle. So its not only the programming language that you have to learn but also underlying techniques that needs to be understood. If you not much interested in web development, you can go for Android.comparing both these technologies are not proper, but largely Android can be learnt bit faster becuase in ASP.Net MVC you will also have to learn Razor, HTML development, ADO.Net or Entity Framework etc.... But whatever you wish to learn will require time, patience & dedication.
