Create a simple screen filter

问题

I saw this post Brightness Screen Filter which describes how to create a simple screen filter.
That code used

private void setBrightness(int brightness) {
try {
  IHardwareService hardware = IHardwareService.Stub.asInterface(
   ServiceManager.getService("hardware"));

  if (hardware != null) {
    hardware.setScreenBacklight(brightness);
  }
 } catch (RemoteException doe) {          
  }        
 }

But i could not find the IHardwareService.jar Can anyone explain me the code that i should use to create this simple app?

Providing the jar file would be also appreciated!
