Java source code for mobile video calls

Recently learning the Android platform for cross-platform audio and video communications development, although there are many open-source projects on the Internet for our reference study, but the audio and video effect is very general, there are a lot of unstable factors, after all, is open source. In China I found a better audio and video communication solution, the case provides a pure Java language interface for us to call, then I refer to the official Android demo program and development documentation and combined with my own insight wrote an android audio communication software, Within 200 lines The code is done (hard to believe). In fact, I just call its relevant API to implement. Here is my own Java code, in case everyone learns from each other:

/**
* Android Video Chat
* 1, initialize the SDK 2, connect the server, 3, user login, 4, enter the room, 5, open the local video; 6, request the other side of the video
*/

Read the official development document in detail you will find that the Android audio and video solution also has text chat, send files, peer-to connect and other very useful features. It's exciting for developers to be able to quickly implement similar QQ chats and audio and video communications.
