android - 错过取消注册我从未注册的 HapticFeedbackBroadcastReceiver 接收器的调用

Question

我得到以下错误

"Are you missing a call to unregister receiver"

当我点击后退按钮退出我的应用程序时。如何识别哪个接收器导致泄漏并消除错误？我正在使用 Google 的代码“DownLoader”下载扩展文件。

Answer 1

解决方案 1.

如果您有一个带有 ItemClickListener 的 ListView，您必须在覆盖方法 onPause 时将监听器设置为 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，则必须始终取消注册并覆盖 onPause 方法。

@覆盖 protected void onPause() {

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

}

我知道第二种解决方案对您不起作用，但我将其提供给您引用。

希望对您有所帮助。
