[smocken78]

i just tested this usecase on iOS device and the login works fine. Is this error occuring on android devices or on iOS devices as well?

I am curious because i received an email from facebook, complaining about a non working login.

Você tem que vincular sua conta do Facebook na conta de desenvolvedor no console do Facebook e depois o hash da sua aplicação e funciona.

Obrigado.

Same issue here. Not working on android. Please fix this - we need to publish our app and this is must have.

I found work round - redirect to FB web view like this: final facebookSignIn = FacebookLogin(); facebookSignIn.loginBehavior = FacebookLoginBehavior.webOnly; ... Now it works!

Same problem. On ios it uses Webview, and it is ok. But on android it doesn't use the installed Facebook app.

@danilof Your workarround works. Btw, this error appear when I have the Facebook app installed to my device and I'm login to it.

hi Guys i solved this problem You need to get Key hash From SHA-1 Key and all working fine

[buidan]

For iOS, I found a working solution by add some extra code to AppDelegate.swift

override func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
         if url.scheme == "fbXXXXXXXXX" {
                return ApplicationDelegate.shared.application(app, open: url, options: options)
         }
        .....
    }

Relace XXXXXXXXX with your facebook ID

Edit AppDelegate.swift

---

import FBSDKCoreKit

override func application(_ application: UIApplication, open url: URL,
                                    options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
            if url.scheme == "fbXXXXXXXXXXXXXX" {
                return ApplicationDelegate.shared.application(application,open:url,options:options)
             }
          .....
}

Download your APK to your PC in java jdk\bin folder

in my case C:\Program Files\Java\jdk1.7.0_121\bin

Go to java jdk\bin folder and run cmd then copy the following command in your cmd

keytool -list -printcert -jarfile yourapkname.apk Copy the SHA1 value to your clipboard like this CD:A1:EA:A3:5C:5C:68:FB:FA:0A:6B:E5:5A:72:64:DD:26:8D:44:84 and open http://tomeko.net/online_tools/hex_to_base64.php to convert your SHA1 value to base64. This is what Facebook requires get the generated hash ****= and copy the key hash to the facebook app.

i got the same issue,try many times. finally i generate a release-apk , add the release-apk's key hashes to the facebook app, then it work may be its relate to security or something ，idk
