Can you make Android new Toolbar to be shown with shadow like you could do with the old ActionBar?
Please refer to the image: Left is ActionBar and you can see it looks "floating" with shadow while the right one is ToolBar, how can you show it the same?

Use attibute android:elevetion=4dp on toolbar.
