It will only modify the screen while that window/activity is being shown to
the user. This allows it to be done in a safe way (no permission required)
which the system can recover from if there is a bug in the application (or
if the application gets killed for some reason, as we tend to do).

for example right now i was thinking to write a simple app just
changing the brightness
in a simple way. not just for a window, for the whole system.
Often I am out and just like a simple "change brightness", without
searching through
the setup (imagine i am in the sun and already dont see anything) so
even 2 steps
are far away.
anyhow.. is there an intent how i can easily open the popup where i
can change the
system brightness?
thanks
chris

And it doesnt work. It seems to change the brightness value on the
Display Settings Screen but not the actual display brightness. I tried
with putString too, no game.
I also tried to use the IHardware approach (described by joby some
messages ago), but it seems to doesn't even exist on SDK 1.1 (at least
eclipse could not resolve it).
But there must be one way working because the Flashlight app on the
Market does that perfectly. So, if anyone can provide a different
approach I will be very thankful.

It never existed on the SDK 1.1 as an official API, so the SDK won't know about it.

What SDK are you targetting?
For SDKs 1.0 and 1.1, the API was unfortunately there but not official to make flashlights.
For SDK 1.5 there's a new *official* way to do a simple flashlight. No hacks involved and you're guaranteed it will work. Dianne posted the 2 lines of code that you need earlier in the thread.
It must still be possible in 1.5 cupcake:
- "PowerManager" can set it
- "Settings -> Sound&Display -> Brightness" can change it
- haven't checked "Locale"
While the system setting might have privileged access to the API, the
PowerManager is just a normal program. So how do they do it?
This is indeed frustrating..... however, there's a funny new
wrinkle.... whenever I use the new cupcake-approved sugar-free method,
the brightness stays after I go back to the home screen. (yay) I seem
to have problems when brightness gets too low though (IE, cant do
anything with the unit ... obviously). So do yourself a favor and put
a lower limit on it ;) I set mine to .1.
