I&#39;m trying to make a login with Facebook available in my script. I&#39;ve done everything, but when I attempt to login with a Facebook account I get this error from Facebook:

&gt; Error
&gt; 
&gt; App Not Setup: The developers of this app have not set up this app properly for Facebook Login.

Here&#39;s error screenshot:

The developers of this app have not set up this app properly for Facebook Login?

I have followed the instructions here: 

https://stackoverflow.com/questions/21329250/the-developers-of-this-app-have-not-set-up-this-app-properly-for-facebook-login/26135600#26135600

Made my app public and the circle is green so the app is public.

But when I try to login, I go to the Facebook app, it asks me to login which I do and then I get this message:

App Not Setup: This app is still in development mode, and you don&#39;t have access to it. Switch to a registered test user or ask an app admin for permissions.

BTW: I am the admin

Any help is much appreciated. I am using SeattleClouds and this happens on both iOS and Android.

I have problem about login with facebook acount in my application. I read to Facebook Doc. And I did  all step as Facebook Doc. 

First in login with facebook acount in app - **SUCCESSFUL** ! and than logout in application. I want to login **again** with my facebook acount. **But not working** !! And I took this Excepiton ! Please help me !


**Exception : This app has no Android Key hashes configured.Configure your app key hashes at http:developers.facebook.com/apps/&quot;APP ID&quot;**

Finaly; I used to part of code for HashKey Genarate 

     try {
            PackageInfo info =     getPackageManager().getPackageInfo(&quot;MY PACKAGE NAME&quot;,     PackageManager.GET_SIGNATURES);
            for (android.content.pm.Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance(&quot;SHA&quot;);
                md.update(signature.toByteArray());
                String sign=Base64.encodeToString(md.digest(), Base64.DEFAULT);
                Log.e(&quot;MY KEY HASH:&quot;, sign);
              //  Toast.makeText(getApplicationContext(),sign,     Toast.LENGTH_LONG).show();
            }
    } catch (NameNotFoundException e) {
    } catch (NoSuchAlgorithmException e) {
    }



**I resolved my issue.** I should have done setting on Facebook. 
Steps :

 1. Go to facebook developer&#39;s page :
    [https://developers.facebook.com/][1]  
 2. Open the App tabs and than
    click the Setting
 
 3. Paste the generate hashkey on HashKey&#39;s field =  If you don&#39;t have it yet, get your key hash part of code 
 4. And than **Single Sign On will be &quot;Yes&quot; : Single Sign On: Enable this setting.**

I wanted to share my resolve. Maybe someone need this solution. Good Luck !

After updating to Xcode 9, I tried to build one of my projects.

I use the **FacebookLogin** pod.
I have a compiler error in FacebookLogin/LoginButton.swift

    @testable import FacebookCore
    ❌ Module compiled with Swift 3.1 cannot be imported in Swift 4.0

In my target&#39;s build settings, the Swift language version is set to **Swift 3.2**.

[![Screenshot added][1]][1]

I guess I need to wait for Facebook to update their pod ? Or any other suggestion ?

Thanks !

I am getting this error. When I try to sign in with facebook to my app.
When I first time authentication it will correctly working. After I unistalled my application and now trying to sign in with Facebook on that I am getting this error.

**Another Issue** : After authenticate in device1 and try to login with facebook on device2 also same error is getting.

**Solution I Found :** when I remove App authentication from Facebook App Settings it is working in above scenario&#39;s but this is not an good solution how we can tell to users to do this action?

I already tried several answers I could find but none of them worked with the latest Facebook Android SDK version 4.0.

How can I change the layout height with the latest SDK?

How to change the height of the &#39;Log in with Facebook&#39; button?

As I understand from the [Firebase Docs][1], if a user authenticates his account with a credential, he should strictly login by using the same credential if the credential is not linked with another one yet.

In other words, if I create an account by using Google sign in, and then (after sign out) try to login with Facebook credential by using the same email that is used for Google credential, I should see this exception in logcat:

&gt; &quot;An account already exists with the same email address but different
&gt; sign-in credentials. Sign in using a provider associated with this
&gt; email address.&quot;

And yes, I get this exception unsurprisingly. But if I create an account by using Facebook, and then try to login with Google credential, the provider of this account (Facebook) is converted to Google. This time authentication does not fail but it is not the expected result. I want to associate each user with a specific credential in a way. How should I fix this? You can see the code below:

Authentication using Facebook at first and then Google causes an error in Firebase for Android

I&#39;m trying to import fb-login function and there are some features which need to be inspected by facebook such as job status, education, etc.
And they&#39;re saying that they requires privacy policy URL. So, I made a facebook page, which I will use as a landing page for my app, and wrote down the Privacy Policy to the Note.

After that, I copied the note&#39;s url and pasted it to the Privacy Policy URL box. I tried to save and proceed, but than error message comes up, 

&gt; Facebook URL: Facebook URL cannot be crawled

So, my question is this: Is it unavailable to use facebook page to submit the privacy policy URL? This is my first time importing fb-login, so I just don&#39;t know what should I do and what shouldn&#39;t I do.

How should I deal with the Facebook app privacy policy URL in developers page?

My script has code like this

&lt;!-- language: lang-php --&gt;

    echo &#39;&lt;p class=&quot;wdfb_login_button&quot;&gt;&lt;fb:login-button scope=&quot;&#39; .
         Wdfb_Permissions::get_permissions() . &#39;&quot; redirect-url=&quot;&#39; .
         wdfb_get_login_redirect() . &#39;&quot;&gt;&#39; .
         __(&quot;Login with Facebook&quot;, &#39;wdfb&#39;) . &#39;&lt;/fb:login-button&gt;&lt;/p&gt;&#39;;

How to change facebook login button with my custom image

I am trying to create facebook sign-in page according to [this][1] tutorial. I only changed the two lines 

    appId      : &#39;370675846382420&#39;, // App ID
    channelUrl : &#39;//http://bp.php5.cz/channel.html&#39;, // Channel File

and I get the following error


&gt; Given URL is not allowed by the Application configuration.: One or
&gt; more of the given URLs is not allowed by the App&#39;s settings. It must
&gt; match the Website URL or Canvas URL, or the domain must be a subdomain
&gt; of one of the App&#39;s domains.

What might be the problem?

Given URL is not allowed by the Application configuration

Hey I know this was asked before, but none of the solutions seem to help. I&#39;m using first time Facebook SDK in my application.
    
What I&#39;ve tried:

    
I had tried most of the things found on **Internet** but did not get anything regarding this.
    
Here is my MainActivity.java:

     public class MainActivity extends Activity {

      @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        FacebookSdk.sdkInitialize(getApplicationContext());
       } 
    }


Here is My Activitymain.xml:

     &lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
    xmlns:tools=&quot;http://schemas.android.com/tools&quot;
    xmlns:facebook=&quot;http://schemas.android.com/apk/res-auto&quot;
    android:layout_width=&quot;match_parent&quot;
    android:layout_height=&quot;match_parent&quot;
    android:orientation=&quot;vertical&quot;&gt;
 
     &lt;com.facebook.login.widget.LoginButton
        android:id=&quot;@+id/connectWithFbButton&quot;
        android:layout_width=&quot;wrap_content&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:layout_centerInParent=&quot;true&quot;
        android:layout_gravity=&quot;center_horizontal&quot;
        android:text=&quot;  connect_with_facebook&quot; /&gt; 
    &lt;/LinearLayout&gt;
see my **Logcat**:
    
     05-13 16:30:39.332: E/AndroidRuntime(10264): Caused by: The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first.

    
     


Facebook Sdk Has Not Been Initialized FacebookSdk.sdkInitialize()

I have updated iPhone 6 plus to iOS 9 beta and trying to perform Facebook login but each time its presenting UIWebView with Facebook login form. 

I have Facebook sdk 

    FB_IOS_SDK_VERSION_STRING @&quot;3.24.0&quot;
    FB_IOS_SDK_TARGET_PLATFORM_VERSION @&quot;v2.2&quot;

And I am using following methods to perform Facebook Login 

        NSArray *permissions = @[@&quot;email&quot;,@&quot;user_birthday&quot;,@&quot;public_profile&quot;];
        
        
         FBSessionStateHandler completionHandler = ^(FBSession *session, FBSessionState status, NSError *error) {
             [self sessionStateChanged:session state:status error:error];
         };
         
         if ([FBSession activeSession].state == FBSessionStateCreatedTokenLoaded) {
         // we have a cached token, so open the session
             [[FBSession activeSession]openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
                                     fromViewController:nil
                                      completionHandler:completionHandler];
         } else {
             
         [self clearAllUserInfo];
        [[NSURLCache sharedURLCache] removeAllCachedResponses];

         // create a new facebook session
         FBSession *fbSession = [[FBSession alloc] initWithPermissions:permissions];
         [FBSession setActiveSession:fbSession];
         [fbSession openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
                  fromViewController:nil
                   completionHandler:completionHandler];
         }


I have following setting under plist file

    	&lt;key&gt;LSApplicationQueriesSchemes&lt;/key&gt;
    	&lt;array&gt;
    		&lt;string&gt;fbapi&lt;/string&gt;
    		&lt;string&gt;fbapi20130214&lt;/string&gt;
    		&lt;string&gt;fbapi20130410&lt;/string&gt;
    		&lt;string&gt;fbapi20130702&lt;/string&gt;
    		&lt;string&gt;fbapi20131010&lt;/string&gt;
    		&lt;string&gt;fbapi20131219&lt;/string&gt;
    		&lt;string&gt;fbapi20140410&lt;/string&gt;
    		&lt;string&gt;fbapi20140116&lt;/string&gt;
    		&lt;string&gt;fbapi20150313&lt;/string&gt;
    		&lt;string&gt;fbapi20150629&lt;/string&gt;
    		&lt;string&gt;fb-messenger-api20140430&lt;/string&gt;
    		&lt;string&gt;fbauth&lt;/string&gt;
    		&lt;string&gt;fbauth2&lt;/string&gt;
       &lt;array&gt;
Please let me know what I am missing here. First it is checking for `iPhone device Setting-&gt; Facebook credentials` but never open Facebook app for login. Seems it does not recognize Facebook app installed on device.
