title: androids putExtra
body: <p>I'm having thoughts abut my current app.
  I have this TabHost class with two tabs. 
  Tab1 shows data from a WS in a Listview. Tab2 shows the same data as a diagram in a webview.</p>
  
  <p>Of course, I'd rather not call the same webservice for the same data twice, so I was thinking of doing the WS call already in the TabHost class and then send the data as a JSONArray to both my tabs using putExtra.</p>
  
  <p>Is that possible or simply stupid?
  Regards</p>
