Answer 1

You need to explicitly define the 'attr' type in the item in AS 3.0

eg.

<item type="attr" name="colorPrimary">@color/primaryColor</item>

Docs: https://web.archive.org/web/20180518223123/https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration

Also, don't forget to define the attribute in your attrs.xml. eg.

<declare-styleable name="Theme">
    <attr name="colorPrimary" format="color|reference" />
</declare-styleable>
