Android okvolley framework, androidokvolley

I have recently made many new good things and have no time to take a good look. Now I have to review them and take notes.

I remember that the framework I used previously was android-async-http, volley, or something else. Then I went on to get okhttp, retrofit, and rxjava, and there were a lot of new things, I am not a programmer. I am just a porter on github. If so many people come to learn and post articles, I will learn it myself, because volley was used in the past, so I didn't use retrofit, because volley also supports okhttp. As for why okhttp is used, I won't say much about it. After all, it's not a great guy, it's just a little white, and the code is the best teacher, the next step is to use the framework body of okhttp and volley.

Learning notes, for reference only, can also be optimized here, such as removing the network callback and switching to rxandroid
