Android Widget Configure

view story

http://stackoverflow.com – I created a android widget and when I added a configure activity the widget launch a kind of activity and close it but the widget don't show, Its obviously something wrong with the code in my Configure class: package com.rb.widget; import android.app.Activity; import android.os.Bundle; public class WidgetConfig extends Activity{ @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); } } How should a configure class look like ?
