JAVA source code for mobile video calls and java source code for calls

I recently learned how to develop cross-platform audio and video communication on the Android platform. Although there are many open-source projects on the Internet for our reference, the audio and video effects are common and there are many unstable factors. After all, they are open-source. In China, I found a better solution for audio/video communication. In this case, we provided a pure Java interface for calling, then I wrote an android audio communication software by referring to the official android demo program and development documentation, and combining my own insights. I got the code within 200 lines (I can't believe it ). In fact, I only need to call its related APIs. The following are the Java code I have written to help you learn from each other:

/**
* Android video chat
* 1. initialize SDK 2, connect to the server, 3. log on to the user, 4. enter the room, 5. Open the local video, and 6. Request the recipient's video.

After reading the official development documentation in detail, you will find that the Android audio/video solution provides useful functions such as text chat, File Sending, and P2P connection. It is exciting for developers to quickly implement QQ chat and audio/video communication.
