Android 更改屏幕方向后广播接收器崩溃且不工作

我有两个广播接收器来观看短信状态。 代码：

这两个接收器位于名为initSMS（）的过程中。initSMS（）在OnCreate（）方法中调用一次。一切正常，但以下情况令我失望。当用户更改屏幕方向时，android抛出异常，应用程序被抑制。LogCat告诉我程序不想第二次注册BroadcastReceiver。我认为没有问题，并在OnCreate（）中添加了一个布尔标志，以便下次跳过initSMS（）调用。但是，即使第二次跳过initSMS（）调用，第一次更改屏幕get here的方向也是LogCat中的一个新错误：

活动已泄漏到IntentReceiver

一旦发生这种情况，就不可能跟踪SMS的状态，接收器无法工作。但是，如果用户尝试播放并继续更改方向，则在任何情况下都不会出现错误

--

谁知道，发生了什么事？ 类似于块权限的变通方法更改方向并不有趣。我需要了解这里发生了什么并解决当前的问题
