Android Video Call Java code

Recently learned the development of cross-platform audio and video communications under the Android platform, although there are many open source projects available on the Internet for our participation. 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 (Baidu download official anychat for Android demo), the case provides a pure Java language interface for us to call, then I took the official Android Demo program and develop documentation and combine your own insights to write an Android audio communication software. Within 200 lines The code is done (hard to believe).

In fact, I just invoke its relevant API to implement. Here is my own Java code, in case everyone learns from each other:

The Android audio and video solution is also useful for text chat, sending files, and peer connections.

For developers, the high-speed realization of similar QQ chat, voice and video communication is an exciting thing.
