My Program don't work on any android device

I published an App to the Market but it is not available on HTC Desire and Motorola Milestone ... This is the part from the Manifest that i understand filters the devices:

<supports-screens android:smallScreens="false"
 android:normalScreens="true"
 android:largeScreens="tru开发者_运维技巧e"
 android:anyDensity="true" android:resizeable="false"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESSNETWORKSTATE" />
<uses-permission android:name="android.permission.WRITEEXTERNALSTORAGE" />

Does anybody have a hint for me?

Permissions are ok - but why don't you support small screens?

Desire is a 3.7 - which is on the larger end of the small screen range: http://developer.android.com/guide/practices/screens_support.html http://www.htc.com/uk/product/desire/specification.html
