Android广播接收器未注册报错

Question

我使用 Intent 打开位置设置菜单以在我的 Activity 中启用 gps。调用 Intent 后我使用服务来收听位置更新。我发送了两个 BroadcastReceivers 从 Service 到 Activity。在 Activity 的 onResume() 方法中，我想访问从 Service 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。但是我已经注册了两个 BroadcastReceivers。

错误:

Answer 1

那是因为 - 您正在注销 broadcastreceiver both 方法中的 s onStop()和 onDestroy() .

您必须一次注销接收器。尝试从 onStop() 中删除注销代码方法。
