Answer 1

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
}

Use the above given code to hide the status bar from the app. Also, don't forget to apply your keyboard visible condition.
