Opening PDF with navigateToUrl on Android

Hi,

i'm developping an enterprise application in AIR on Android which show a list of PDF's on your device and should open them when you press on it.

However, when using navigateToUrl for this purpose, it doesn't open the PDF in Adobe Reader (which is installed) but in another app, called HP IPrint.

Even uninstalling HP IPrint, setting Adobe Reader as the default app for reading PDF files doesn't change this behaviour. It either opens it in HP IPrint, or if IPrint is not available not at all. Opening the PDF from outside the AIR app with Adobe Reader works fine however.

Since openWithDefaultApplication is not supported under the mobile profile, how do I make AIR open PDF's in Adobe Reader?

Thx in advance.
