Android Webview and Facebook Login Not working
提问by Gayan Hewa
I am having a problem with a WebViewapp that I am working on.
我正在使用的WebView应用程序出现问题。
We have this responsive website that is being displayed through an android WebView.
我们有这个响应式网站，通过 android 显示WebView。
The website has a Sign in with Facebookoption, this works fine in a mobile browser and on the website itself. Whenever I try to use the WebViewapp to login using Facebook, it results in a white screen.
该网站有一个使用 Facebook 登录的选项，这在移动浏览器和网站本身中都可以正常工作。每当我尝试使用该WebView应用程序登录时Facebook，都会导致白屏。
I am having difficulties finding a solution to get this to work.
我很难找到解决方案来让它发挥作用。
Appreciate any advise.

I'm fairly certain it's this same issue. Essentially it opens in another window and WebViewdoesn't support multiple windows out-of-the-box.
我很确定这是同一个问题。本质上，它在另一个窗口中打开，并且WebView不支持多个开箱即用的窗口。
Luckily for you, unlike that question which was iOS-specific, if I recall correctly, it's possible to extend WebViewto support multiple windows. You'll need to extend WebChromeClient, implement onCreateWindowand use it in your WebView.
幸运的是，与特定于 iOS 的问题不同，如果我没记错的话，可以扩展WebView以支持多个窗口。你需要扩展WebChromeClient，实现onCreateWindow在你使用它WebView。
