Sarina DuPont from Embarcadero released an updated Android theme which contains new styling for Android Kitkat 4.4. The styling isn’t much different from the older Android styling but if you want to stay up with the latest Android look and feel this is what you should use. There is a dark style and a light style included. It also includes style templates for the Bitmap Style Designer if you need them. This updated style came out in January but there is also an interesting piece of code with it that shows you how to apply a style based on the version number of the OS it is running on. You could expand this code to handle multiple versions (like IOS 6 and IOS 7) and operating systems. Here is the sample code:
if TOSVersion.Check(4, 4) then StyleBook := KitKatStyleBook;
