I want to use webrtc in my android app.
https://github.com/pchab/AndroidRTC
after import project from this site video calling or voice calling or chatting is not working.
how can i use websocket library send data and receive for video or voice chatting?
can we interface WEBRTC API with webview.
or how can we do voice chatting and display view in chrom in any control of android.
now i am using webrtc in a native app but it is not working.
if u have any other code or project for webrtc in android than send me link.

我想在我的Android应用中使用webrtc。 https://github.com/pchab/AndroidRTC 从该站点导入项目后，视频通话或语音通话或聊天无效。我如何使用websocket库发送数据并接收视频或语音聊天？我们可以将WEBRTC API与webview连接。

要使此应用程序正常工作，您需要一个服务器端来执行信令工作。如果您不想自己开发，可以使用来自同一项目的桌面客户端安装node.js服务器（只需遵循AndroidRTC的How To说明和ProjectRTC的安装说明）：

希望它有所帮助。
