Facebook App Page not found

Question

I am using facebook-login in my android app. Everything works fine I can upload and post images with my android app, but below the posted images is "posted via [appname]". If I click at [appname], I get a "page not found". So I filled out everything in App-Details but I can't submit my app for review, because:

Before you can submit your app detail page you must first comply with App Center Guidelines. Please make sure you have specified how your app integrates with Facebook and have met all the requirements. Click here to update your integration.

So I clicked there "to update my integration" Image from Settings

The only point I can't fill out is "App Domains". What does it mean? play.google.com doesn't work.

The page app-details is filled 100%

Answer 1

To make your Facebook app visible, you need to have a Facebook page (or perhaps a link to a web site) for your application, in App Details - Contact Info section. If you don't have it create it following "Create a new Facebook page" link
