Mobile Apps Developer

These are code names for Android releases, and are well known throughout the Android community. Your developer should be familiar with them. Ice Cream Sandwich was Android version 4.0 (API level 14) released on October 18, 2011. KitKat refers to Android version 4.4 (API level 19), released on October 31, 2013.
