Unable to set screen brightness in android when I am blocking status bar expansion using WindowManager.LayoutParams.TYPE_SYSTEM_ERROR overlay

Question

I am developing Kiosk android app where I am blocking android status bar expansion using WindowManager.LayoutParams.TYPE_SYSTEM_ERROR overlay.

Issue with this fix is I am unable to change screen brightness. To update brightness I am using following code.

if (mWindow == null) mWindow = getWindow();
WindowManager.LayoutParams layoutParams = mWindow.getAttributes();
layoutParams.screenBrightness = brightness;
mWindow.setAttributes(layoutParams);

To disable status bar expansion I referred Prevent status bar for appearing android (modified)

Any help ? Unable to handle both feature together. – BMascarenhas May 07 '18 at 10:25 — BMascarenhas, May 07 '18 at 10:25

With SYSTEM_ERROR overlay, it is not possible to handle screen brightness. So I am blocking status bar only when onWindowFocusChanged, and blocking for only 3 minutes. Then removing overlay so that I am able to handle screen brightness.
