Android采用消息推送实现类似微信视频接听

本文实例为大家分享了Android实现类似微信视频接听的具体代码，供大家参考，具体内容如下

1、背景需求：业务需要接入视频审核功能，在PC 端发起视频通话，移动端显示通话界面点击接听后进行1对1视频通话。

2、解决方案：因为项目没有IM功能。只集成了极光消息推送(极光消息推送接入参考官方文档，经过跟需求沟通，采用消息推送调起通话接听界面。再集成腾讯实时音视频SDK（具体集成方式参考官方文档）。最终实现类似微信1对1通话功能。

3、技术实现：

A:编写一个广播接收器，并且在 AndroidManifest中注册，这就是一个全局的广播接收器。应用退到后台或者应用进程被kill，只要极光的push进程是Live，就能接受到消息，启动通话接听界面。

总结：项目中考虑时间和成本问题。没有接入IM功能。消息推送不可靠，极光的push进程被杀，是收不到消息。当打开app后，会蹦出很多通知。这只是简易的实现了在pc调起移动端进行视频通话。这有很多因素是没有考虑进去的，在此先记录下吧。
