Question

I have made a XML file:

Answer 1

I'm not sure it's the same, but Similar issue happened to me when updating to ADT 15, in a library project. this is the google issue that currently still opened: 21046.

That's what worked for me:

1. Remove the library declaration of the project.
2. Open the layout causing the error (the one which using the selector) in graphical layout.
3. Clean the project (Project -> Clean)
4. Close and reopen eclipse. (the layout should be ok now)
5. You can set the project as library again.

Hope this helps! (if it's still relevant...)
