Hi, Mobile application development process is the set of procedures involved in programming and building software or applications for fast operating handheld devices like smart phones and tablets. 

Also talking about the qualification, you need to do science degree. The major platforms are Android, Apple, Windows, Symbian, and RIM (Blackberry). You can learn to code for all of these platforms, but you probably need to choose one when you're first staring out.

This should help you. Let me know incase you seek any other information.

All the best!
