Hi, thanks for the information about breaking out the ICS stack into its own library. That's very interesting, and I'll look at including it in Spring Android. I'm nearing an RC1 release right now, and beyond testing on ICS, I haven't spent any time addressing any new ICS features. This is largely because there is very little adoption of ICS at the moment. Spring Android 1.0 will be released with Froyo (2.1) support, but the Froyo usage rate is dropping, so I can see us moving forward to a 2.2 minimum in the near future. At this point, since there has been a bit of a gap from the M4 release, I'm not scheduling any new features for 1.0. I'll plan on looking at incorporating support for this library in the next release iteration.
