Final answer:
In Android, a specified icon for an item is displayed in the action bar, while text representations of the item are used in the options menu.
Step-by-step explanation:
By default, if you specify an icon for an item, Android uses that icon in the action bar, but it uses text for that item in the options menu.
When designing an Android app, it's important to understand how icons and text are displayed in different areas. The action bar typically shows icons for actions that can be taken immediately, which is conducive to quick access and saving space on the screen.
On the other hand, the options menu, which is accessed by pressing the menu button, often uses text to provide a clear understanding of each action available, due to the more expansive space.
By default, if you specify an icon for an item, Android uses that icon in the action bar, but it uses text for that item in the overflow menu.
