Android combine Retrofit + RxJava Tutorial

RxJava is the good java library for android development which composing asynchronous and event-based programs. It is a better than AsynTask because it has more control of the thread and more features to use. For retrofit, its supports the asynchronous and synchronize thread but its does not able to get much control of the thread. So we use use rxJava to replace with the retrofit asynchronous method. In this tutorial, I will tell you about android combine retrofit + rxjava in the project so you can be more understand about it.
