Android L Theme.Material无法识别

Question

I'm trying to change my app's status and navigation bar colors and so far nothing I've tried has worked. My project is targeted to L.

Here is my styles.xml in values-v21 folder.

<style name="CalcTheme" parent="android:Theme.Material">        
    <item name="android:colorPrimaryDark">@color/primary_dark</item>
    <item name="android:colorPrimary">@color/primary</item>
    <item name="android:colorAccent">@color/accent</item>

    <item name="android:statusBarColor">@color/primary_dark</item>
    <item name="android:navigationBarColor">@color/primary_dark</item>
</style>

The problem is none of these changes are working when I run the project on my Nexus 5 (running L)
