“De Icaza noted that Google doesn’t always seed their Android
development kits as fast as the actual Android releases are
announced. With Android 3.x, Google didn’t even make a full open
source release, making it difficult for software development firms
like Xamarin. In contrast De Icaza said that with Apple iOS they
can often ship updates within 24 hours of an Apple iOS release.One of the key new additions in Android 4 is that Mono
developers will now be able to take advantage of improved graphics
handling capabilities. De Icaza noted that Android 4 has a new
rendering engine for graphics that takes advantage of GPU based
textures.“Android 4 now has most of the iPhone-like rendering
capabilities,” De Icaza said.
