问题
I want to use telegram APIs in order to develop chatting feature in My Existing Android App. I am not getting how to implement.
回答1:
I think, it is a good idea to take a look at the Telegram Database Library (Beta) from here TDLib (Russian, but translate with Google) and the Java doc (English) from here.
The information is a little poor yet, but I think you can understand it.
回答2:
Use this API.
Refer to the Getting Started section to integrate Telegram in your app.
