Is there any facebook application in Sony Xperia and Motorola Droid X2? Then open Facebook.java and find this code and comment just 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);
    }
}

hope this helpful to you. because when there facebook application installed it's activate single sign on with facebook application and your application need to register in your app in facebook. See here for more clear information. http://developers.facebook.com/docs/guides/mobile/android/
