App is misconfigured for Facebook login Android Facebook integration issue

Question

I've linked Facebook with my app, and I'm doing this via utilising Facebook's Graph API. I'm getting information on my friends and profile. On my Android 2.3 (Gingerbread)-powered handset, it functions without a hitch, but my client recently encountered a problem when he tried to login to Facebook using my app. On his device, he has Android 4.0 (Ice Cream Sandwich). He taps a button on the app to access the Facebook login screen, and after logging in, he sees the following message:

My app is misconfigured for Facebook login. Press Okay to go back to the application without connecting to Facebook.

I'm not sure what the issue is, whether it has to do with the Android version or not.

How am I going to fix this issue?
