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 (Baidu download official anychat for Android demo), 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 in combination with their own ideas to write an Android audio communication software, 200 lines of code is done (hard to believe it). In fact, I just call its relevant API to implement. Here is my own Java code, in case everyone learns from each other:

The Android audio and video solution also has a very useful function such as text chat, send files, peer-to connect, etc. It's exciting for developers to be able to quickly implement similar QQ chats and audio and video communications.
