		* flags, we would like a stable view of the content insets given to
		* {@link #fitSystemWindows(Rect)}. This means that the insets seen there
		* will always represent the worst case that the application can expect
		* as a continue state. In practice this means with any of system bar,
		* nav bar, and status bar shown, but not the space that would be needed
		* for an input method.
		* as a continuous state. In the stock Android UI this is the space for
		* the system bar, nav bar, and status bar, but not more transient elements
		* such as an input method.
		*
		* The stable layout your UI sees is based on the system UI modes you can
		* switch to. That is, if you specify {@link #SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN}
		* then you will get a stable layout for changes of the
		* {@link #SYSTEM_UI_FLAG_FULLSCREEN} mode; if you specify
		* {@link #SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN} and
		* {@link #SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION}, then you can transition
		* to {@link #SYSTEM_UI_FLAG_FULLSCREEN} and {@link #SYSTEM_UI_FLAG_HIDE_NAVIGATION}
		* with a stable layout. (Note that you should avoid using
		* {@link #SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION} by itself.)
		*
		* If you have set the window flag {@ WindowManager.LayoutParams#FLAG_FULLSCREEN}
		* to hide the status bar (instead of using {@link #SYSTEM_UI_FLAG_FULLSCREEN}),
		* then a hidden status bar will be considered a "stable" state for purposes
		* here. This allows your UI to continually hide the status bar, while still
		* using the system UI flags to hide the action bar while still retaining
		* a stable layout. Note that changing the window fullscreen flag will never
		* provide a stable layout for a clean transition.
		*
		* <p>If you are using ActionBar in
		* overlay mode with {@link Window#FEATURE_ACTION_BAR_OVERLAY
