我有如下代码所示的Android 何时何地注销宽频广播接收器？,android,broadcastreceiver,android-broadcast,android-broadcastreceiver,Android,Broadcastreceiver,Android Broadcast,Android Broadcastreceiver,我有如下代码所示的aAsyncTask，它的任务是启用蓝牙适配器。在onPreExecute中，我注册了操作action\u STATE\u CHANGED，以获得有关蓝牙适配器电源状态的通知（打开、关闭、打开、关闭）。此接收器在onPreexecute中注销，以便在异步任务完成时注销接收器“并在on cancelled中注销”，这样，如果按下“后退”按钮，任务将被取消，接收器应被删除 未注册” 但是，当任务正在运行且我按下后退按钮取消正在运行的任务时，我收到以下logcat错误，尽管接收器已在
