Android .xml files: Why do predefined colors not work for me?

Question

When I look at misc. Android tutorials and examples when it comes to specifying colors I very often see constants like @color/red or @color/black e

Answer 1

Make sure your color XML file is within the values folder, not a colors folder.

So you should have...

values/colors.xml

    #FF0000

and NOT this...

color/colors.xml

    #FF0000

Note that the tag is resources, not selector.
