Question

我收到以下错误

当我按下后退按钮退出我的应用程序.如何识别哪个Receiver导致泄漏并消除错误？我使用Google的代码"DownLoader"下载扩展文件.

解决方案1.

如果你有一个带有ItemClickListener的ListView你必须在overrive方法onPause上将监听器设置为null.

listView.setOnItemClickListener(exampleListener);

示例:您的听众声明

private OnItemClickListener exampleListener = new OnItemClickListener() {}....

@Override
    public void onPause() {

        super.onPause();

        listView.setOnItemClickListener(null);

    }

@Override
    public void onResume() {

        super.onResume();
            if(listView != null){
                listView.setOnItemClickListener(exampleListener);
             }
    }

解决方案2 如果您知道什么是您的broadcastReceiver实例您必须取消注册始终un overrive方法onPause.

@Override protected void onPause(){

    super.onPause();
    synchronized (this) {
        if(broadcastReceiverInstance != null){
            unregisterReceiver(broadcastReceiverInstance );
        }
    }

}

我知道它的第二个解决方案对你不起作用,但我让它作为参考.

我希望它可以帮到你.

Answer 2

您必须对您在 Activity 中注册的任何接收器调用 unregisterReceiver()。这通常在 onPause() 中。
