This dimension was used in old versions to determine the height of action bar , currently it does not exist. 

<!-- Default height of an action bar. -->
<dimen name="abc_action_bar_default_height_material">56dp</dimen>

You can add this value to your dimens.mxl file. If this file does not exist, to create it you do it this way:

create a file called dimens.xml and add the entry: 

<?xml version="1.0" encoding="utf-8"?>
<resources>    
    <dimen name="abc_action_bar_default_height_material">56dp</dimen>   
</resources>

and obtain the reference in this way: 

android:layout_height="@dimen/abc_action_bar_default_height_material"
