 使用xposed让被完全停止的应用响应fcm，让fcm送达率达到100%，不错过任何通知  
 
 - 允许fcm唤醒选中的应用来发送通知
+- 解除miui12对后台应用的通知限制(非miui系统没影响)
 - 修复在国内网络下出现重连服务出现负数问题(貌似是miui优化的问题)(可选)(需要查看自己手机上gms的版本编辑配置文件)
 - 固定心跳间隔为117s(可选)(需要查看自己手机上gms的版本编辑配置文件)

 ```
+注: heartbeatInterval 设置为0的话则不固定心跳间隔时间，使用原本的自适应

 - 9. 最后将配置文件的enable修改true，保存，重启手机
 
 - 10. 一般来说gms更新改变的只有类名也就是timer_class
