And one more interesting fact - if I add the jars as External Jars using Eclipse, building the workspace takes a while, eventually it runs out of memory and it only generates the resources file (no apk and no dex). If I add the jars as Lib (as I showed in the previous posting), the workspace is built fast, all archived deployable files are generated but no jars are include ... something seems a bit out of wack here - anyone else saw this before?
