If I add the 96x96 line to the app-xml file and do a Publish from Flash, that line is deleted from the app-xml file and the 72x72 icon is placed in the XHDPI folder in the apk.
app-xml pre-build:
<icon>
<image48x48>AppIconsForPublish/icon_square_48.png</image48x48>
<image72x72>AppIconsForPublish/icon_square_72.png</image72x72>
<image36x36>AppIconsForPublish/icon_square_36.png</image36x36>
<image96x96>AppIconsForPublish/icon_square_96.png</image96x96>
</icon>
app-xml post build:
<icon>
<image48x48>AppIconsForPublish/icon_square_48.png</image48x48>
<image72x72>AppIconsForPublish/icon_square_72.png</image72x72>
<image36x36>AppIconsForPublish/icon_square_36.png</image36x36>
</icon>
I suppose I can go back to manually packaging the app - but would it be that big a deal to add the icon as it is supposed to be added in the same way the others are handled?
This is a known issue and is planned to fixed in next release of Flash Professional. For the time being, could you please package your application through command line using adt (http://help.adobe.com/en_US/air/build/WS901d38e593cd1bac1e63e3d128cdca935b-8000.html). Please let us know how it goes.
