What library are you using for REST method for android applications?

Question

Android

What do you recommend?
1)Groundy
2)Retrofit
3)AnnotatedSQL
4)Android db-commons
5)Android Annotations
The library is needed only for a simple client-server. And how much will it take to rewrite the code used in one library for another? Or just change a couple of values?

Answer 1

Retrofit

Answer 2

And I use Volley. It seems to be simpler than Retrofit, although the code is longer.
