提问by hellowill89
I am getting this error when the device changes orientation:
当设备改变方向时，我收到此错误：
Error: WebView.destroy() called while still attached
Error: WebView.destroy() called while still attached
With this code:
使用此代码：
protected void onDestroy()

What is the reason for this? How do I avoid this error?

You first need to detach the Webview:
您首先需要分离 Webview：
webViewPlaceholder.removeView(myWebView);
myWebView.removeAllViews();
myWebView.destroy();
That did it for me.
那是为我做的。

To avoid the error you just need to remove all views before you destroy the ad.
为避免该错误，您只需在销毁广告之前删除所有视图。
@Override
public void onDestroy()
{
if (adView != null)
{
adView.removeAllViews();
adView.destroy();
}
super.onDestroy();
}

@Override
public void onDetachedFromWindow() {
super.onDetachedFromWindow();
if (mWebView != null) {
mWebView.destroy();
}
}

According to my tests, this issue is revealed in AdMob SDK v6.4.1 and at least on Android v4.2.2+. When testing the AdMob sample application referred to at https://developers.google.com/mobile-ads-sdk/docs/admob/fundamentals#android(direct link is http://google-mobile-dev.googlecode.com/files/Android_XML.zip), the issue occurs when closing the sample screen.
根据我的测试，这个问题在 AdMob SDK v6.4.1 中出现，至少在 Android v4.2.2+ 上。在测试https://developers.google.com/mobile-ads-sdk/docs/admob/fundamentals#android（直接链接是http://google-mobile-dev.googlecode.com/ files/Android_XML.zip)，关闭示例屏幕时会出现此问题。
My work-around is rather:
我的解决方法是：
@Override
public void onDestroy()
{
// Destroy the AdView.
if (adView != null)
{
final ViewGroup viewGroup = (ViewGroup) adView.getParent();
if (viewGroup != null)
{
viewGroup.removeView(adView);
}
adView.destroy();
}
super.onDestroy();
}
Hope that helps other people, and that the AdMob will very soon fix that annoying issue.
希望对其他人有所帮助，并且 AdMob 将很快解决这个烦人的问题。

For you don't get this error you need to have a parent layout, e.g. : RelativeLayout and remove the WebView component, that might had been defined on you layoutWebView.xml.
因为您没有收到此错误，您需要有一个父布局，例如：RelativeLayout 并删除可能已在您的 layoutWebView.xml 上定义的 WebView 组件。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/webviewRelativeLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<WebView
android:id="@+id/webView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/headerAlarmsWebViewTxt"
android:layout_marginBottom="0dip"
android:hapticFeedbackEnabled="true"
android:overScrollMode="never"
android:scrollbarAlwaysDrawVerticalTrack="false"
android:scrollbars="none" />
</RelativeLayout>
Then you assign it to an instance variable e.g. :
然后你将它分配给一个实例变量，例如：
_layout = (RelativeLayout) findViewById(R.id.webviewRelativeLayout);
webView = (WebView) findViewById(R.id.webView1);
and on Destroy do something like this:
在 Destroy 上做这样的事情：
@Override
protected void onDestroy() {
super.onDestroy();
_layout.removeView(webView);
webView.setFocusable(true);
webView.removeAllViews();
webView.clearHistory();
webView.destroy();
}
