应用程序试图调用被破坏的 WebView - cordova (Android)

Question

当我在移动设置中更改字体大小时(settings->Display->Font size) 我的科尔多瓦应用程序重定向到索引页面（意味着根页面）， 我得到了

应用程序试图调用已销毁的WebView

我的日志：

谁能帮我解决这个问题。

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“应用程序试图调用已损坏的 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();
}

StackOverflow 的其他答案说要对 void onDestroy() 进行上述三个调用，但我仍然遇到同样的问题。工作解决方案 如上所示，您希望将 adView.destroy() 与 removeAllViews() 调用分开。

我还建议您在适当的地方致电adView.resume() 和adView.pause()。
