Unable to retrieve access token for facebook on real device

I did Facebook integration in my project, everything is fine on emulator. When it comes to run on real device it is not working. I think the problem is Facebook access token, I don't know what to do now? So I am unable to retrieve friends information on real device. Can anybody help me how to get access token on real device.

I am using Android SDK only to get the Facebook friends information.

mFacebook = new Facebook("api_id");
mFacebook.authorize(this, new String[] {
    "publish_stream", "read_stream", "offline_access", "friends_birthday", "user_birthday", "email", "read_friendlists", "manage_friendlists"
}, this);
sToken = mFacebook.getAccessToken();
public void onComplete(Bundle values) {
    Log.e("oncomplete", "value");
    if (values.isEmpty()) {
        Log.e("oncomplete", "value is empty");
        return;
    }
    if (!values.containsKey("POST")) {
        sToken = mFacebook.getAccessToken();
        getFriends()
    }
}
private void getFriends() {
    try {
        sToken = mFacebook.getAccessToken();
        StaticUtils.sResponseId = mFacebook.request("me/friends");
        Log.w("response", StaticUtils.sResponseId);
        try {
            JSONObject jObj = Util.parseJson(StaticUtils.sResponseId);
            JSONArray jArr = jObj.getJSONArray("data");
            for (int i = 0; i < jArr.length(); i++) {
                JSONObject jObjFren = jArr.getJSONObject(i);
                Iterator it = jObjFren.keys();
                while (it.hasNext()) {
                    String s = (String) it.next();
                    // Log.w("KEY",s);
                    String sname = jObjFren.getString(s);
                    if (s.equals("id")) {
                        StaticUtils.sFbId.add(sname);
                        StaticUtils.sFbPics.add(StaticUtils.sImgUrl + sname + "/picture");
                    } else if (s.equals("name")) {
                        StaticUtils.sFbName.add(sname.toLowerCase());
                    }
