Android灯应用源码，包括霓虹灯效果。(Android lamp application source code, including the neon light effect.)

I created this app to simulate the ring behavior of the Motorola RAZR which would switch to loud when charging and return to vibrate-only when disconnected (no manual adjustment needed). This app also allows the reverse scenario (silent when connected otherwise ring). This tutorial assumes you already have the Eclipse environment up and running. If you are new to Eclipse and Android development, I recommend going through the temperature converter tutorial which can be found here.
