I can't follow your question, but the code your posted has problems. First, please don't set Settings.System.SCREEN_BRIGHTNESS. This is the global brightness set by the user. It should not be changed by the application. It is not intended to be changed by the application; generally there are other things you need to poke to have the system pick up the new value, and this is all in the realm of implementation details that you shouldn't rely on and almost certainly will not work consistently across devices and platform versions.
Second, you also have some code that is setting WindowManager.LayoutParams.screenBrightness. If you set this on your full-screen window, then while it is displayed on the user it will force the screen brightness to the value you set here. You do need to make sure your activity is full-screen. If it is, and your activity is in the foreground, it will cause the brightness to change. In this case you are immediately starting another activity and finishing the current one, so it will only very briefly impact the screen brightness (if it all) for however long that activity remains visible to the user.
