title: Different GUI on phone and tablet, but same app
body: <p>I have to write an app for tablet and for phones too. The two app has the same functionality, but they have absolute different GUI. </p>
  
  <p>For example the phone have 2 button on the main screen, but the tablet going to have 5, because we would like to use the space what we have. I know, I˜m able to define different layouts, depends on dpi, but how should I handle the layout-s in the Activiies? I think, to use if(sdkVersion >=11) bla..bla... is not will works through the hole code and the hole project! Is this the situation where I have to use multiple application support ?</p>
