AppCompat does not use the android:
prefixed attributes for the Material Theme color palette items per the migration guide to v21 by the author of AppCompat. Instead, just use the names themselves:
<style name="AppTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">@color/primaryDef</item>
<item name="colorPrimaryDark">@color/primaryDarkDef</item>
<item name="colorAccent">@color/primaryDef</item>
<item name="android:navigationBarColor">@color/primaryDarkDef</item>
<item name="android:activatedBackgroundIndicator">@drawable/defbg</item>
</style>
The Action Bar will be colored by colorPrimary
.
