Can not access Facebook session - UnknownError: Invalid application

Question

I'm using Prime31 SocialNetworking plugin for Unity3D with Facebook SDK 3.5 and trying to login Facebook on the Android 2.3.5 device. Facebook application is installed on my device and a Facebook user is logged in prior to application launch. Default login behaviour SSO_WITH_FALLBACK is used.

When I initiate a login from my application I observe the following behaviour:

1. When the application starts the Facebook session is in CREATED state.
2. A permissions dialog prompts me to allow basic read access for my application.
3. I click OK and then my main application activity is shown instead of Facebook's login dialog (maybe it's intentional but Session.getActiveSession().closeAndClearTokenInformation() and Session.setActiveSession(null) are called prior to new Session.OpenRequest(FacebookPlugin.getActivity()) inside Prime31 plugin).
4. My application's Facebook session is not opened (is in CLOSED_LOGIN_FAILED state).

The logcat reports me these lines (package name and Facebook app ID are replaced):

I/Prime31 ( 5077): FacebookPlugin: openActiveSession.call with state: CLOSED_LOGIN_FAILED, exception: com.facebook.FacebookException: Log in attempt aborted.

When I logout from Facebook within the native app the behaviour slightly changes - the login screen appears, but when the main application activity is shown I get the same CLOSED_LOGIN_FAILED session state.

I've checked my application ID and hash key in the Facebook app settings: both are matching to my app's settings. Hash key logcatted by Prime31 plugin is the same as was created on my Windows evironment. When I changed app ID to something different I got another error - "invalid app id". So app id seems to be set up correctly. What else I might miss?

Answer 1

For all who encounter similar issues check your Facebook application sandbox mode and currently active Facebook user when starting your application. In my case I was starting the application which was in the sandbox mode and the current Facebook user was not from the granted list of users in the Facebook application settings.

Answer 2

In case that helps anyone, I had the same problem and it was due to the fact that my test phone had its time set 3-4 months in the future.

Answer 3

This can happen when the facebook application identifies itself with an ID not previously registered at facebook. Go to https://developers.facebook.com , register a new application and you will receive a numerical ID (something like 10 digits) which you should plant in the code. in react-native-fbsdk, this is called facebook_app_id or facebook_application_id.
