Do you love Android JellyBean fame Easter eggs, but your device is running older version of Android? Never mind, we have got a neat trick via XDA developer iamareebijamal, who has written a well explained guide to get all those JellyBean easter eggs to your Android device. Easter eggs are funny and interesting. For instance, the easter eggs you see after tapping Android version several times on JellyBean, KitKat are simply a great sense of creativity. Now you can easily port them to other Android versions as well.
The developer says, the process involves in reverse engineering using the tools like APKTool and derivatives. You have to decompile files, add few lines of code and then recompile the framework. Once done, the changed files have to be loaded onto your device to see the Jelly Bean easter eggs.
You will find the detailed steps on how to achieve this on XDA’s original thread. You will also find few source code as comments in this Stack Overflow thread as well.
