android - Unable to retrieve access token for facebook on real device

Question

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());
                    }
                }
            }
        } catch (JSONException e) {
            Log.w("json exception", e.toString());
        } catch (FacebookError e) {
            Log.w("facebook exception", e.toString());
        }
    } catch (MalformedURLException e) {
        Log.w("malformed exception", e.toString());
    } catch (IOException e) {
        Log.w("io exception", e.toString());
    }
}  

Thanks, Ammu

The code above given is absolutely correct...The problem is if we have already installed any facebook application in our device which are upgraded versions than we are using our application will not work...If we uninstall the facebook applications in our device it will work...and there is also another way to work our application and other facebook application in our device by following steps::: if u r using eclipse then goto

Windows>Preferences>Android>Build and get the path of the debug keystore

now open terminal and run the following command

keytool -export -alias androiddebugkey -keystore "debug keystore path" | openssl sha1 -binary | openssl enc -a -e

it will ask for the password then enter android as ur password Now add the HASH KEY to your Facebook API configuration located @ http://www.facebook.com/developers/ under EDIT SETTINGS / Mobile and Devices screen.

Now i was able to run my application on HTC device
