The source code for the Android 4.2 Jelly Bean operating system is released, and the SDK is available for download which means we would be able to see custom ROMs available pretty soon from developers, and only for those who have the Android 4.2 OS in their devices. The API level 17 of the Android 4.2 SDK includes quite a few features which developers can play with, and make things far interesting.
The SDK includes the native RTL support, with which one can create apps in the native languages such as Arabic, Hebrew, and Persian. There is also inclusion of a variety of font and character optimizations for Korean, Japanese, Indic, Thai, Arabic and Hebrew writing systems.
New interaction and entertainment experiences – Support for the external displays is there, so multiple displays can be attached.
Multiple lock screen widgets can be placed on the lock screen, along with the interactive screensaver named Daydream.
To start developing and testing out the Android 4.2 OS platform, you can download the SDK file from the SDK file manager. Something about the SDK -
