changing screen brightness programmatically in android

Question

I want to change the screen brightness programmatically in android. At the moment I use this code:

WindowManager.LayoutParams lp = getWindow().getAttributes();
float brightness=1.0f;
lp.screenBrightness = brightness;
getWindow().setAttributes(lp);

But this sample code works on cupcake, not on latest versions. I am using the latest version of SDK.. What is the preferred solution for newer Android Versions?

How about using the IHardwareService interface for this? An example can be found in this tutorial.

Update: tutorial link still works, but actual code is also available in next answer.
