How can I tell if the screen is on in android?

Solution
You can accomplish this by setting up broadcast receivers for `ACTION_SCREEN_ON` and `ACTION_SCREEN_OFF`.
Problem
In Android 2.2 (Level 7) the function `PowerManager.IsScreenOn()` returns a boolean that is true if the screen is turned on and false if the screen is turned off. I am developing code for Android 1.5 (Level 3). How do I accomplish the same task in older versions of Android? I do not want to turn the screen on or off in my code. I just want to know what it is.
