- A drawable to use for the up indicator, or null to use the theme's default
Set an alternate drawable to display next to the icon/logo/title when ActionBar.DISPLAY_HOME_AS_UP is enabled. This can be useful if you are using this mode to display an alternate selection for up navigation, such as a sliding drawer.
If you pass null to this method, the default drawable from the theme will be used.
If you implement alternate or intermediate behavior around Up, you should also call ActionBar.SetHomeActionContentDescription(int) to provide a correct description of the action for accessibility support.
