I need to know the languages after java to learn to become a good mobile app designer, both for android n ios,

Answer 1

For Android you need to learn Java. For iOS you should learn Swift, then maybe C++ and Objective-C if you want. Learning other languages after those first 2 will only help. For instance, In an android app I wrote I also used Javascript and Jquery to pass info to a website that didn't have it's own API. If you're going to be working with databases you should also learn SQL or some other derivative like MySQL.
