Tuesday was a big day for Google. Company started selling Nexus 4, Nexus 7 3G and Nexus 10, it began Android 4.2 roll-out for Galaxy Nexus, Nexus 7 Wi-Fi and posted Android 4.2 factory images for all the previously mentioned devices.
But apart from all the above, Google also did two more important things that are very important for app and ROM developers. First, the search giant posted the Android 4.2 SDK on its website.
To get started developing and testing, download the Android 4.2 Platform from the Android SDK Manager. You can read more about highlights of Android 4.2, API level 17 at the Android Developers Blog.
Secondly, Google released the Jelly Bean code in Android Open Source Project (AOSP). This will allow ROM developers like CM to get cracking with the new Android 4.2 based firmware for your devices. It will also allow manufacturers to start working on Android 4.2 updates for the existing devices.
ROM devs can look for Android 4.2 source code under the name “android-4.2_r1” in AOSP.
