Getting the exact screen density on AIR mobile

Hello,

I'm working on a project for which I need to get the exact screen density of
the device but Capabilities.screenDPI doesn't seems to return a precise
value. For example, the constructor specifications of my phone give 401 PPI
but Capabilities.screenDPI returns 480 PPI.

Does anyone knows if there is an ANE that provides a reliable screen density
value ?

Thank you.

Hello,

For those who are interested by this subject, I asked yesterday to Michael
Archbold from Distriqt if a would be possible to add this feature to their 
Application ANE
<http://airnativeextensions.com/extension/com.distriqt.Application>   and he
did it 3 hours later !

API is very simple :

/trace( "DISPLAY METRICS ========================" );
trace( "densityDpi:   " +
Application.service.device.displayMetrics.densityDpi );
trace( "screenHeight: " +
Application.service.device.displayMetrics.screenHeight );
trace( "screenWidth:  " +
Application.service.device.displayMetrics.screenWidth );
trace( "xdpi:         " + Application.service.device.displayMetrics.xdpi );
trace( "ydpi:         " + Application.service.device.displayMetrics.ydpi );
/

This will be super usefull for measuring screen elements accurately.

I highly recommand distriqt for the quality of their ANE and the
professionalism of the support they provide.

Vincent.

Here's one for Android.  Shouldn't be too difficult to adapt for iOS and/or
Desktop.
