title: supporting multiple screen sizes in android
body: <p>Hi I'm new to android world.Iam working on an application that supports multiple screen sizes i did as explained here <a href="http://developer.android.com/guide/practices/screens_support.html#screen-independence" rel="nofollow noreferrer">http://developer.android.com/guide/practices/screens_support.html#screen-independence</a> . I didn't create different xmls for each screen size. But when I tested it on android 3 emulator it appears in small part of the screen.</p>

  <p>So I think that the size specified for my application on the emulator is small so my widgets are not filling the whole screen as I want. Can I control that size of my application on the emulator? </p>
