Problem Filtering android app based on screen resolution

I want my app to be shown in the Market, only for devices with large screen. i.e WVGA800 (480x800, 480x850). Example: Nexus One.

I have done following changes in the Manifest file.

<supports-screens android:anyDensity="true" androi开发者_如何学JAVAd:largeScreens="true" android:normalScreens="false" android:smallScreens="false" android:resizeable="true"></supports-screens>

After uploading, when i try to search in Market using Nexus one, the app is not showing up. I have also tried with other devices having different screen types.

Any help on this will be great.

Thanks

Are you sure the nexus one is a largescreen type phone? I don't think so. If its 480x800 but with "high density", then it's a 'normal' sized screen.

See here: http://developer.android.com/resources/dashboard/screens.html

If this images is correct, there have been very little or no 'large screen' devices on the market in august 2010 e.g. That doesn't proof anything, but i doubt the nexus would be unfindable in this graph ;): http://developer.android.com/guide/practices/screens_support.html
