Question

我收到以下错误

“你是否错过了取消注册接收者的呼叫”

当我点击后退按钮退出我的应用程序时。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。

Answer 1

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。

@覆盖 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。

我希望它可以帮助你。

Answer 2

这是一个解决方法!!我有一个三星标签7“4.2.2

问题原因：
1. 4.2.2
2.在Layout.xml中定义的ListView 3.新的ListView（this）

修复：
1.不要在布局中声明ListView，而是声明持有人
2.使用'getApplication（）'而不是'this''new ListView（getApplication（））;'
3. addView（yourListView）

TheLayoutFile.xml

    <RelativeLayout
        android:id="@+id/listViewHolder"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
    </RelativeLayout>

活动中的ListView

private void displayPostsInListView() {
    RelativeLayout listViewHolder = (RelativeLayout) findViewById(R.id.listViewHolder);
    listView = new ListView(getApplication());
    listViewHolder.addView(listView);
    listView.setOnItemClickListener(lineItemListener);

    adapter = new MyDisplayAdapter(this, listModel.getPostings());

    listView.setAdapter(adapter);
}

Answer 3

您必须在已在“活动”中注册的任何接收者上调用unregisterReceiver（）。这通常是在onPause（）。

Answer 4

如何识别哪个接收器导致泄漏并消除错误？

答案在你发布的LogCat中。

Activity com.ssowens.groovebasstrial.BassActivity has leaked IntentReceiver com.immersion.android.haptics.HapticFeedbackManager$HapticFeedbackBroadcastReceiver@41d166d0 that was originally registered here.

您在HapticFeedbackBroadcastReceiver中注册了BassActivity，暂停或关闭应用时需要取消注册。正如@svenoaks所说，您应该覆盖Activity.onPause()并使用unregisterReceiver(referenceToReceiver);取消注册您注册的每个接收者

缺少取消注册我从未注册的HapticFeedbackBroadcastReceiver接收器的调用
