一、前言
声网音视频SDK是没有呼叫声音的api的，可以说声网音视频SDK文档相当简单，它的demo代码也相当简单。很多东西都没有，如超时挂断，如何通知对方，通知栏，浮悬窗等都没有。
它们SDK只管频道内的数据传输，以及用户在频道内的状态
二、SDK不提供，只好我们自己做
需求：呼叫端用一个mp3,
被呼叫端根据手机铃声情景模式操作：
情景模式是
- 铃声+震动的，调起手机铃声和震动，并且开扬声器
- 铃声的，调起手机铃声，并且开扬声器
- 震动的，调起震动
- 静音的，即静音
第二个需求：在呼叫或者通话中，暂停其他app的声音，通话结束恢复其他app的声音
三、关键代码：CallRingingUtil
public class CallRingingUtil {
private static final String TAG = "CallRingingUtil";
private volatile boolean isRinging;
