facebook-authentication

My application is working fine on emulator. So I decided to run my application on my Android phone. I am trying to login to Facebook account using my application and it works fine on emulator. And as soon as I run my application on android phone I always get this exception- 01-30 11:06:08.400: E/AndroidRuntime(7463): java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=64206, result=0, data=null} to activity {com.facebook.samples.sessionlogin/com.facebook.LoginActivity}: java.lang.NullPointerException Below is my code- @Override public View onCreateView

I'd like to know the simplest way to update a user's facebook status. I'd like to simply display a 'Share' button. When the user touches 'Share': If they are already logged in to Facebook, a dialog will appear giving them the option to edit their posting before submitting to Facebook. If they aren't already logged in to Facebook, the will be prompted to login and then automatically shown the sharing dialog upon successful login. Is there a simple way to do this, or do I need to implement a separate facebook login flow? So I think I've got a pretty clean way to do it. I welcome any comments. I

I'm trying to make a Facebook login with the new Firebase platform. this is the code for the facebook login let facebookLogin = FBSDKLoginManager() facebookLogin.logInWithReadPermissions(["email"], fromViewController: self) { (result, error) -> Void in if error != nil { print("error is \(error)") } else { let accessToken = FBSDKAccessToken.currentAccessToken().tokenString let credential = FIRFacebookAuthProvider.credentialWithAccessToken(accessToken) AUTH?.signInWithCredential(credential, completion: { (user, error) -> Void in if error != nil { print("error is \(error)") } else { print(user)

I am trying to use Facebook to authenticate users. It works ok except for Ajax calls. Most of the times it just send old token and I get : {"error":{"message":"This authorization code has been used.","type":"OAuthException","code":100}} So what I tried doing is wrapping every ajax call with FB.getLoginStatus(function(response) { if (response.status === 'connected') { return fn(); ... this did not worked so I've added : true as parameter to getLoginStatus to prevent caching : FB.getLoginStatus(function(response) { if (response.status === 'connected') { console.log('connected'); fn(); } else if

I've been trying to test out Scores and Achievements using the 'publish_actions' extended permissions but when I add it, it doesn't show up in the Request for Permission page. It's like its ignored. I've tried a couple different ways: $loginUrl = $facebook->getLoginUrl(array('scope' => 'publish_actions', 'canvas' => 1, 'fbconnect' => 0, 'redirect_uri'=>config_item('facebook_url'))); $loginUrl = 'https://www.facebook.com/dialog/oauth?' . 'client_id=' . config_item('fbappid') . '&redirect_uri=' . urlencode(config_item('facebook_url')) . '&state=' . $_SESSION['state'] . '&scope=publish_actions';

[This question is intended as a means to both capture my findings and sanity check them - I'll put up my answer toute suite and see what other answers and comments appear.] I spent a little time trying to get my head around the different social authentication options for (python) Appengine. I was particularly confused by how the authentication mechanisms provided by Google can interact with other social authentication mechanisms. The picture is complicated by the fact that Google has nice integration with third party OpenID providers but some of the biggest social networks are not OpenID

This is a problem i am trying to solve for a month now. (tried any possible article/code out there). In ExternalLoginCallback action, AuthenticationManager.GetExternalLoginInfoAsync() returns a valid object (with all the provider details) but email is null for certain Facebook users . For the large majority of Facebook login email is presetnt. But for about 30% of logins I get an exception down the process because the email is null. Luckily sometime ago I've created a Facebook user which reproduce the problem . I've created a sterile test environment in localhost and indeed email comes null

Sometimes (not very frequently) my android app crashes after first logging to facebook using Facebook Login (Facebook SDK version 3.5). I'm getting exception: java.lang.RuntimeException: Unable to resume activity {my.app.package/com.facebook.LoginActivity}: java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=64206, result=0, data=null} to activity {my.app.package/com.facebook.LoginActivity}: java.lang.NullPointerException with 2 different root exceptions: Sometimes with: java.lang.NullPointerException at com.facebook.AuthorizationClient.startOrContinueAuth
