AIR SDK Issue with Android Build Tools

Our latest application requires us to use some of the more recent features of Android which require some of the v7 support libs. To use these you need to use a version 21+ of the android build tools.

Unfortunately the adt fails with those versions of aapt:

aapt tool failed:ERROR: Asset package include '/Applications/Adobe Flash Builder 4.7/eclipse/plugins/com.adobe.flash.compiler_4.7.0.349722/AIRSDK/lib/android/lib/resources/android-res.jar' not found.

This issue seems to be related to a stricter policy with the way assets are included ?

Anyone found a way around this?

This happens with both the current AIR 18 and the beta AIR 19.
