A couple of days ago, we talked about how you could get some of the KitKat goodies on your Jelly Bean device, thanks to some APKs that were extracted once the Nexus 5 factory images were released. While it is obviously preferable to have the real thing, these KitKat apps are the next best thing if you are on a device without a stable KitKat build—well, other than learning how to build from source and creating a port for your own device yourself.
The previous article focused on getting the launcher, new Hangouts app, Camera, Google Now, and Gallery working. Now, there is a fantastic guide by XDA Recognized Themer ATTACK that shows you how to get KitKat-style gradients in your Status and Navigation Bars, assuming you have an AOSP-based ROM. This involves decompiling, modifying, and recompiling your android.policy.jar and SystemUI.apk files, but there’s a guide for that.
Then to top it all off, XDA Senior Member ivn888 created a thread with all of the KitKat wallpapers, sounds, fonts, and even the boot animation. The wallpapers are available as standard images, and the sounds, boot animation, and fonts are flashable ZIPs.
To get started, head over to the gradient status and navigation bars guide and the wallpapers, boot animation, sounds, and fonts thread.
And for those who want to see the overall product of using these customizations, XDA Senior Member enricocid created a KitKat-flavored ROM for the Galaxy Nexus incorporating these goodies. While it’s not KitKat, and there are already some highly-functional builds available, the look is pretty convincing._________
