How to adjust screen bright immediately in service not activity? I use Android SDK 1.5
i tried WindowManager.LayoutParams lp = getWindow().getAttributes(); lp.screenBrightness = 1.0f; getWindow().setAttributes(lp); but it can't work in service because service has no getWindow() and I tried brightness = Settings.System.getInt(getContentResolver(), Settings.System.SCREEN_BRIGHTNESS) it's no use in service so how to adjust screen bright "immediately" in service? And when I call goToSleep() in PowerManager, it shows SecurityException but i already add permission DEVICE_POWER to manifast but it's still wrong why? thanks. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
