How to write an Android client-server application?

Question

Android

Hello!
I want to write my own client-server application, for example, to work with api VK, but I don’t really understand where to start.
A bunch of simple applications for android have been written and now I want to go into working with the network, so I need to move on.
Thanks

Answer 1

There are roughly 3 components in the client-server history:
1) Server - for you, this is the VK server
2) Client - this is what you want to write
3) Protocol - in your case, JSON over HTTP
In total, all these 3 components in VK are implemented in in the form of an architectural pattern of REST
In summary, you need to:
1) Learn the RestFull API implementations in VK and Android
2) Learn json
3) Learn the HTTP implementation in Android

Answer 2

Well, you probably need to start by learning Api vk if you already have experience in developing for android.
