Facebook app is Public, but gives error "App not setup" when logging in

Question

I have an Android app using Facebook to login.

The app is already public:

When trying to login via Facebook, I get this exception:

com.facebook.FacebookAuthorizationException: App Not Setup: This app is still in development mode, and you don't have access to it. Switch to a registered test user or ask an app admin for permissions.

Since the test users are able to login perfectly fine, I'm assuming that my code if fine.

Are you asking for more permissions other than public_profile,user_friends,email – Manas

Yes, user_birthday and user_about_me, but those are approved for the app as well. Please see the screenshot. – Tantivy

I see, have you added a contact email as well? (IN most cases, the logged in fb user i.e. the app creator) . If yes, then check if the package names are correct for the android app in the settings. Those are pretty much the checks to make it work really. – Manas

Yes, added contact email and all other possible details. The important thing is that that app is marked public. See the FILLED GREEN dot beside the App Name. – Tantivy

@Slartibartfast did those checks...Also, test users are able to login and use the app.. so those details are definitely correct. – Tantivy

If the problem persists, file a bug at developers.facebook.com/bugs – Aeri

I am having the same problem in ios. Were you able to solve this?? – Ketron

I created a new Facebook app. No resolution on the old app. – Tantivy

Answer 1

If the app status says that the App is public, yet you see the error with the SDK login, create a new app and start over.

This is a bug on facebook's end.

Answer 2

1. In Settings → Basic → Contact Email → give your or any email.

2. Make sure you have a valid Privacy Policy available.

3. In the App Review Tab change:

   Do you want to make this app and all its live features available to the general public?

   to Yes.

Answer 3

I also encountered this issue because I used wrong app id and app secret. Please use valid app id and app secret.

I did check that all relevant details were correct. – Tantivy

Answer 5

Unlike Google, Facebook api needs a valid ssl certificate. So if your website isn't https then according to facebook you are still in development mode. Here is the link to their docs https://developers.facebook.com/docs/apps/security

For development purposes you can use the roles option (can be found on the leftside menu). In here you can enroll your self as a developer or tester to use all the live features.

Once you are done with the development you will have to get an ssl certificate. You can also use a free service like https://letsencrypt.org to get a valid certificate, facebook requires your certificate to be sha256WithRSAEncryption, i personally haven't used letsencrypt with facebook yet but they are one of their sponsors to i guess it should meet their criteria of a decent certificate.
