WebView manipulation

You can attach a WebViewClient to the WebView with the setWebViewClient() method. When the loading of the page is finished, you can examine the URL that was loaded (onPageFinished()) and identify if it may be problematic on the current device. If it is probable, then you can run a javascript command that can modify the styles so that the scrolling is not disabled any more. I haven't tried to do this modification yet but I'm pretty sure it can be done as any DOM modification is possible from javascript.

I don't say this is a stable solution. You need to monitor it closely in production but a possible way out of the dead end as FB seems to be reluctant to handle it properly.

Built-in browser solution

您可以使用内置的浏览器来实现登录和授权过程。使用URL启动意图https://www.facebook.com/dialog/oauth?client_id={app-id}&redirect_uri={redirect-uri}（本文中的示例：向浏览器发送意图以打开特定的URL）

redirect-uri授权完成后，该参数将告知浏览器返回您的应用。（示例：从android浏览器启动自定义android应用程序）您应该使用scheme模式。
