title: How to create android app with app widget in single application
body: <p>I have already done one <strong>android application</strong> which stores date with person name and phone number.</p>
  
  <p>Now I have to develop one <strong>widget</strong> for this application to show today's (date, person name, and phone number) with button.</p>
  
  <p><strong>Requirements:</strong></p>
  
  <ol>
  <li>Single application with app and widget.</li>
  <li>When I click on a button which is in the widget, it will start my
  application.</li>
  <li>Widget data should always synchronize with my app - when today's
  day (person 5 and application add 5 more person then widget display
  10 person data)</li>
  <li>How can I design this widget? Any guidelines? I have to use
  horizontal ScrollView.</li>
  </ol>
  
  <p>I have done a simple widget demo but I don't know how to synchronize it with my application.</p>
  
  <p>Please share your experience and give some idea about my widget and application.</p>
