Does this also work when using HEX ARGB values, e.g. view.backgroundColor = "#e6202020", where e6 is a semi-transparent alpha value? This was working on both Android and iOS using SDK 5.4.0.GA. After app rebuild with 6.1.0.GA, this no longer sets the view transparency on Android. Fine on iOS under 6.1.0.GA.
