screen-brightness

Is it possible to animate the screen brightness change on iOS 5.1+? I am using [UIScreen mainScreen] setBrightness:(float)] but I think that the abrupt change is ugly. I don't know if this is "animatable" in some other way, but you could do it yourself. For instance the following example code was hooked up to "Full Bright" and "Half Bright" buttons in the UI. It uses performSelector...afterDelay to change the brightness by 1% every 10ms till the target brightness is reached. You would pick an appropriate change rate based on some experimenting. Actually the refresh rate is, I think, 60 hz so

How would I program the ability to change brightness in-app? I know that its possible as I have seen at least three apps that can do it. This would be very useful for my app. I know that it's only possible in iOS 5 with the UIScreen Class, but I have no idea how to program it. Please help me! The UIScreen class has a new property called brightness . In addition, there's another property called wantsSoftwareDimming that (when set to YES ) allows you to go below the lowest brightness supported by the hardware, because a special "dimming view" is overlaid over the screen to darken things even

I want ajust screen brightness by my self. Because Windows lets me only adjusting in limited range. I want dim the display from 0 to 100% and turning it off/on. It should be possible if windows can it do automatically (Dim display after: x minutes/Turn off display after: x minutes). I tried some sources and classes what I found by google. But no of them works. Have you ever tried this or can you recommend me any working code? Thanks for responds. You can use the WmiSetBrightness method: using System.Management; //... static void SetBrightness(byte targetBrightness) { ManagementScope scope =

I'm attempting to change the screen brightness from withing a service, like so: android.provider.Settings.System.putInt(getContentResolver(), android.provider.Settings.System.SCREEN_BRIGHTNESS, bright); Problem is that is doesn't work. Well, actually it succeeds in changing the brightness setting, but the screen brightness doesn't actually change till I go into the phones settings, look at the new value and hit Ok. Is there something I have to do after setting the value to get the brightness to change? I've had the same problem of changing screen brightness from within a service, and a couple

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. This

I want to change the system brightness programmatically. For that purpose I am using this code: WindowManager.LayoutParams lp = window.getAttributes(); lp.screenBrightness = (255); window.setAttributes(lp); because I heard that max value is 255. but it does nothing. Please suggest any thing that can change the brightness. Thanks Ritesh Gune You can use following : //Variable to store brightness value private int brightness; //Content resolver used as a handle to the system's settings private ContentResolver cResolver; //Window object, that will store a reference to the current window private
