来自android.webkit.WebViewClassic.loadDataWithBaseURL中的Webview的Java nullpointer异常

根据this question中提供的建议,我修改了我的AdMob代码以符合建议,这有效地减少了出现的异常数量.然而,一个新的例外正在上升.

代码如下：

@Override
protected void onDestroy() {
    if ( adView != null ) {
          adView.destroy();
          adView = null;

          Log.i(ApplicationData.APP_TAG, TAG + ": OnDestroy, destroying the Adview");
     }

    super.onDestroy();
}

随着LogCat消息的发布,方法adView.destroy()似乎运行良好.在此消息之后,我在WebView上收到以下异常：

java.lang.NullPointerException
    at android.webkit.WebViewClassic.loadDataWithBaseURL(WebViewClassic.java:2741)
    at android.webkit.WebView.loadDataWithBaseURL(WebView.java:919)

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:600)
    at dalvik.system.NativeStart.main(Native Method)

不幸的是,我无法找到重现问题的方法,但是经常在生产中发生.我一直没能找到任何问题,有人暗示我能做些什么吗？

解决方法:

谷歌移动广告SDK团队之一(3月14日)表示,

We looked into this issue when it was first reported, and a fix has been released within Google Play services. You should see fewer and fewer instances as your users’ devices update to the new version.
