I was receiving similar error, but for adView (which is a webview). This helped me to fix my error with "Application attempted to call on a destroyed WebView." Replace adView with the instance of a WebView, should work.

我收到了类似的错误，但对于 adView（这是一个 webview）。这帮助我解决了“应用程序试图调用被破坏的 WebView”的错误。将 adView 替换为 WebView 的实例，应该可以工作。

 @Override
public void onDestroyView() {
    if(adView != null) {
         //rootView is the inflated view of the fragment/activity
        ((ViewGroup) rootView.getParent()).removeAllViews();
        adView.removeAllViews();
        super.onDestroyView();
    }
}

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

Other answers from StackOverflow say to make the above three calls on void onDestroy() but I continued to experience same problems. The working solution as seen above, you want to separate the adView.destroy()from removeAllViews()calls.

StackOverflow 的其他答案说要对 void onDestroy() 进行上述三个调用，但我继续遇到同样的问题。就像上面说的工作方案，要分开adView.destroy()的removeAllViews()电话。

I also recommend you call adView.resume()and adView.pause()in appropriate places.

我还建议你打电话adView.resume()和adView.pause()在适当的地方。
