被Facebook SDK提供的，然后我有这样的变化打开Facebook.java：

Open Facebook.java provided by facebook sdk and then i had changes like this:

public void authorize(Activity activity, String[] permissions,
            int activityCode, final DialogListener listener) {

        boolean singleSignOnStarted = false;

        mAuthDialogListener = listener;

      /*  // Prefer single sign-on, where available.
        if (activityCode >= 0) {
            singleSignOnStarted = startSingleSignOn(activity, mAppId,
                    permissions, activityCode);
        }
        // Otherwise fall back to traditional dialog.
        if (!singleSignOnStarted) {*/
            startDialogAuth(activity, permissions);
       // }
    }
