重要：升级 Android14 后出现报错：One of RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED should be specified ……

老项目升级到Android14出现错误：

根据错误定位到问题是由于使用了一个三方库导致的：

implementation 'com.jeremyliao:live-event-bus:1.7.3'

进一步分析三方库错误原因：

Caused by: java.lang.SecurityException: com.lydsto.robotvacuum: One of RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED should be specified when a receiver isn't being registered exclusively for system broadcasts

错误描述翻译过就是：在注册广播接收器（application.registerReceiver()）时需要 指定导出标志 为RECEIVER_EXPORTED 或者 RECEIVER_NOT_EXPORTED；

查看三方库源码进一步确认问题：

确实是没有根据版本判断进行flags赋值，修改后：

问题解决。

总结：Android14 强制要求  注册广播接收器（application.registerReceiver()）时需要 指定导出标志 为RECEIVER_EXPORTED 或者 RECEIVER_NOT_EXPORTED。
