How to prevent url to show in web view
问题
你好，我正在尝试创建一个应用程序，在应用中我使用了网页视图来展示我的谷歌驱动器文件夹。但是每当在加载网址的过程中遇到断网情况，会显示一个包含正在显示的网址信息的消息。
我应该如何防止用户看到这些显示中的网址呢？
在网络连接在开始时或在开始加载后断开时，是否有可能显示一些其他的消息呢？
英文:
Hi there I am trying to create app where I am using web view to show my google drive folder but whenever internet got disconnect in between loading the URL at that a msg comes with showing the URL information.
What can I do to prevent showing URL from users.
Is it possible to show some other msg whenever internet goes down on starting or when it goes down on after starting loading.

可以！您可以在应用程序启动后立即检查以下方法，然后打印消息或将用户重定向到其他活动...
DD4YouConfig dd4YouConfig = new DD4YouConfig(context);
if (dd4YouConfig.isInternetConnectivity()) {
//重定向到 Webview
}
else {
//调用警告对话框，指示无互联网连接
}
这是一个库函数，所以在 Gradle 中务必不要忘记添加以下行：
implementation 'in.dd4you.appsconfig:appsconfig:1.3.3'
英文:
Yes! You can either print the message or redirect the user to some other activity by checking the following method soon after the app gets launches...
DD4YouConfig dd4YouConfig = new DD4YouConfig(context);
if (dd4YouConfig.isInternetConnectivity()) {
//redirect to webview
}
else
{
//call alert dialog stating no internet
}
This is a library function so obviously don't fail to add this line in Gradle
> implementation 'in.dd4you.appsconfig:appsconfig:1.3.3'

I have a custom HTML page that will show if something wrong happened when loading the url.
