Unlike most other mobile OSes, Android allows users to modify its source code to make the most of it. This is accomplished by editing code from the AOSP or AOSP-derived projects before compiling. However, not all of us build our own ROMs from source. Thus, there’s the world of decompiling and Smali editing.
Here on XDA, developers create amazing things. One new and exciting project allows users to create external controls for SystemUI.APK. The project comes in the form of a guide written by XDA Recognized Developer and Themer serarj, and it allows users to change the look of the status bar and other UI elements on the fly. But rather than simply providing completed applications that accomplish this goal, Serarj decided to share his knowledge and show others how to do this themselves in Eclipse.
If you are a ROM chef and want to add something interesting to your work, or if you simply wish to use it in your own personal builds, your way to the guide thread to get started.
