The Android Support Library also provides other attributes you can use to customize your theme extended from Theme.AppCompat (such as the colorPrimary attribute shown above). These are best viewed in the library's attrs.xml file

Note: Attribute names from the support library do not use the
android:prefix. That's used only for attributes from the Android framework.
