Make Your Gingerbread ROM Look Like KitKat
Android 4.4 KitKat was released two months ago, and it brought a lot interesting changes like a transparent status bar. But not many of you know that you can get a very similar effect on any ROM, even Gingerbread, and all you need to do is to visit the thread we’re going to describe below. With APK tool and good text editor like Notepad++, Gedit, or any UNIX-based notepads, you can easily make your status bar use a gradient background.
XDA Senior Member kk9999gada wrote a guide to describe the process of decompiling SystemUI.apk to make the status bar transparent. He also provides the resources (a PNG file) needed to get this effect on your MDPI or LDPI device. The process of making your status bar more KitKat-like is very simple and takes a minute or two, so can be done while sipping some British tea. This modification proves that not only new, powerful devices with official and unofficial KitKat builds can have some of the best of Google’s UI tweaks.
If you have a Gingerbread device and want to add a transparent status bar to your favorite ROM, head over to the original thread and learn what exactly needs to be done.
