Android 9上的ERR_CLEARTEXT_NOT_PERMITTED，允许域明文

Question

在Android10设备上，我在http服务器上的webview中得到一个ERR_CLEARTEXT_NOT_PERMITTED错误，但仅在某些页面上，即使我使用network_security_config允许该域。我只能通过打开所有域来解决这个错误。我怎样才能修复这个，所以只有我的域是允许的，而不是接收错误，但没有使用？

07:54:09.004 com.myserver.myapp D/myapp: Webview.onPageStarted called on http://myserver.com/myapp/index.php?view=discrete
07:54:09.232 com.myserver.myapp I/myapp: onPageFinished called.

07:54:16.012 com.myserver.myapp I/myapp: onPageFinished called.

<network-security-config>
<domain-config cleartextTrafficPermitted="true">
    <domain includeSubdomains="true">localhost</domain>
    <domain includeSubdomains="true">myserver.com</domain>
</domain-config>
    <!-- Want to delete this for better security--> 
    <base-config cleartextTrafficPermitted="true"/>
</network-security-config>

根本原因是为第三方广告内容服务的javascript（Google Ads）没有使用HTTPS。

已将代码添加到onReceivedError以记录导致问题的URL...

public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
            super.onReceivedError(view, request, error);
            Log.i(TAG, "onReceivedError called for URL "+ request.getUrl().toString());
}
