I have implemented Login with Facebook using
https://ccoenraets.github.io/ionic-tutorial/ionic-facebook-integration.html
I've added SiteUrl as http://localhost:8100 in Facebook App Settings page.
It is working perfectly fine in browser when I use ionic serve but when i build the APK and running on mobile it is saying
Given URL is not allowed by the Application configuration: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.
Where could the issue be? I really doubt how http://localhost:8100 works.
