I want to remove the shadow below the ActionBar.
I know that I need to change the elevation to 0dp, but I want to do it in the theme.
For Android 4.4- I use : <item name="android:windowContentOverlay">@null</item>
But is it possible for Android 5.0 ?

As shown by Antonio Jose, here is an answer : Remove shadow below actionbar
For Android 5.0, if you want to set it directly into a style use:
<item name="android:elevation">0dp</item>
and for Support library compatibility use:
<item name="elevation">0dp</item>
Example of style for a AppCompat light theme:
<style name="Theme.MyApp.ActionBar" parent="style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<!-- remove shadow below action bar -->
<!-- <item name="android:elevation">0dp</item> -->
<!-- Support library compatibility -->
<item name="elevation">0dp</item>
</style>
Then apply this custom ActionBar style to you app theme:
<style name="Theme.MyApp" parent="Theme.AppCompat.Light">
<item name="actionBarStyle">@style/Theme.MyApp.ActionBar</item>
</style>
For pre 5.0 Android, add this too to your app theme:
<!-- Remove shadow below action bar Android < 5.0 -->
<item name="android:windowContentOverlay">@null</item>
