Question

i'm tring to remove the ActionBar Shadow in Android L. On API 14 this code works

<style name="AppBaseTheme" parent="Theme.AppCompat.Light"/>

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:windowContentOverlay">@null</item>

On Android 5.0, Action Bars use an elevation to provide the shadow. You can remove the elevation programmatically via getSupportActionBar().setElevation(0)
