[android-developers] Re: Accessing System Brightness
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.

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.

[android-developers] Re: Accessing System Brightness
hmm but i also dont like that so much. 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 On Apr 16, 11:40 am, Dianne Hackborn hack...@android.com wrote: // Make the screen full bright for this activity.
