■ Current conclusion
问题已定位，修改中
■ My analysis
从Log中分析可知Launcher发生ANR，具体trace文件如下：

1、从以上log中可知，SharedPreference在写文件时候editor使用了commit方法，此方法为同步方法，同时代码中使用了Runtime.getRuntime().exec("sync"); 强制写入磁盘，此方案是早期MCU断电逻辑中为了保证Activity存写，此处频繁同步写入数据出现ANR问题。
2、当前过压保护方案不需要同步保存Activity，所以取消强制写入磁盘，同时SharedPreference保存数据使用apply异步保存方式。

■ Next action
1、SharedPreference保存数据使用apply方法。
2、取消强制写入磁盘数据方法。

无响应ANR问题已经解决提交，目前存在上滑手势失效的问题，正在分析中。

当前的进度：
1、分析手势异常原因。

下一步AI：
1、梳理手势inputConsumer的构建机制和生效时机。

#7 Updated by CD APP-王营 about 2 years ago

■ Current conclusion
ANR问题已解决，优先入库，过压保护触发后拉起Activity，目前系统自带应用手势正常，测试中微信和QQ会出现手势失效的问题，后面新起一个bug来跟进手势问题。
