未捕获 IllegalArgumentException

Question

一个非常奇怪的错误...我在 onResume() 和 onPause() 方法中注册和取消注册接收器。下面是 onStop() 方法中的代码：

    try{
        this.unregisterReceiver(this.sdCardReceiver);
    }catch(IllegalArgumentException e){
        Log.d(MyOwnLife.LOG_LIFEGALLERY, "ActivityVideo - onStop unregisterReceiver:"+e);
    }

我收到以下错误：

Caused by: java.lang.IllegalArgumentException: Receiver not registered: myownlife.pigeau.activityVideo.ActivityVideo$SdCardReceiver@405443f8

我发现了错误……但我的应用程序还是崩溃了……有什么想法吗？

这是完整的日志：

Answer 1

我假设你得到的异常不是从你的代码中抛出的，甚至不是从 Activity 类代码中抛出的，而是在某个系统级库中创建的，所以没有办法正确处理它。

在这里您可以找到解决方法： Android - BroadcastReceiver unregisterReceiver issue (not registered)

Answer 2

如果你使用的是本地广播，那么试试这个

 onPause(){
  LocalBroadcastManager.getInstance(this).unregisterReceiver(broadcastReceiver);
  }
