Android question. Is there a link to a simple example of changing the screen brightness for an activity?

Question

There are apparently at least three different techniques for changing screen brightness in the Android OS. Two of them no longer work post-cupcake and the third accepted technique evidently has a bug.

I would like to increase screen brightness at the start of a one-view activity then turn the brightness back to the user setting at the end of the activity. No buttons, no second view or second activity. Just a maxed brightness at start and a return to original brightness setting at the end of the activity.

The examples of the current technique using WindowManager.LayoutParams that I have located range from 2 lines of code

WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = 100 / 100.0f;
getWindow().setAttributes(lp);

to several pages of source code and numerous activities.

Is there a simple example of maxing the screen brightness at start that someone can provide a link to?

Thank you for reading my question.
