AnyChat音视频通信实现
朱宏爽
去Anychat的官网下载Android的SDK,并将SDK集成到Android Studio中。代码如下，有空再整理bolg做详细讲解。先上传代码。

当我们把AnyChat的开发环境搭好后，我们需要部署我们的服务器，详细参考：http://bbs.anychat.cn/forum.php?mod=viewthread&tid=8&extra=page%3D1
当然看官方给的开发者手册是最好的选择。如果你想先看到效果，而不想去读那数十页的开发文档。你可以将上面的代码copy到你的Android Studio中并做少许更改即可实现音视频通信。
下面来讲解上述代码：
先看OnCreate()方法
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
remoteSurfaceView = (SurfaceView) findViewById(R.id.surfaceview_remote);
localSurfaceView = (SurfaceView) findViewById(R.id.surfaceview_local);
configEntity = ConfigService.LoadConfig(this);//加载视频通话设置
loginSystem();// 初始化SDK 连接服务器
mTimerTask = new TimerTask() {
public void run() {
Message mesasge = new Message();
handler.sendMessage(mesasge);
}
};
mTimer.schedule(mTimerTask, 1000, 100);
handler = new Handler() {
@Override
public void handleMessage(Message msg) {
VideoChat();// 不间断显示即时视频通话画面
super.handleMessage(msg);
}
};
}
remoteSurfaceView = (SurfaceView) findViewById(R.id.surfaceview_remote);
localSurfaceView = (SurfaceView) findViewById(R.id.surfaceview_local);
remoteSurfaceView = (SurfaceView) findViewById(R.id.surfaceview_remote);
localSurfaceView = (SurfaceView) findViewById(R.id.surfaceview_local);
