Android广播接收器未注册错误

Question

我已经使用 Intent 打开“位置设置”菜单以在我的 Activity 中启用GPS。调用 Intent 后，我​​使用了一个服务来监听位置更新。我BroadcastReceivers从 Service 发送了两个到 Activity。在onResume()Activity 的方法中，我想访问从服务传递的数据。但是当我单击后退按钮时，应用程序崩溃了。它说BroadcastReceiver尚未注册。但我已经注册了两个BroadcastReceivers.

Answer 1

那是因为 - 您正在取消注册方法和中broadcastreceiver的 s 。 onStop()onDestroy()

您必须立即注销接收器。尝试从方法中删除注销代码onStop()。
