Android-Facebook-Single-Sign-On-Fehler

Question

Ich versuche, Facebook SSO in meiner Android-App zu implementieren. Die native Facebook-App wird geöffnet. Nach Abschluss des Anmeldevorgangs wird „500:“ angezeigt.Interner Serverfehler. Was mache ich falsch?

Jeder Vorschlag wird sehr geschätzt.Hier ist mein Code

public class FacebookUtil {

    public static Facebook facebook = new Facebook(AppConstants.FACEBOOK_APP_ID);
    String FILENAME = "AndroidSSO_data";
    private static SharedPreferences mPrefs;

    private static FacebookSucessListener mFacebookSucessListener;
     public static final String FB_APP_SIGNATURE ="xxxxxxxxxxxxxxxxxxx"; 
    public interface FacebookSucessListener {
        public void onSucess(boolean isSucess);
    }
    public static void postToWall(){
        facebook.dialog(mContext, "feed" , new DialogListener(){

            }
            public void onComplete(Bundle arg0) {

            public void onError(DialogError arg0) {

            }});

Bitte beziehen Sie sich auf dieses

Android-Single-Sign-On

Und probieren Sie auch dieses aus ...

"Enhanced Auth Dialog" sollte sein disabled in application settings um Ihr Problem zu lösen.
