Android Dev in Eclipse: Strange Error Message

Question

I created a test project and added two XML files. When I save the project, I get an error message that doesn't make any sense.

[2011-11-10 10:21:04 - Testing] res\layout\MainList.xml: Invalid file name: must contain only [a-z0-9_.]

[2011-11-10 10:21:04 - Testing] res\layout\MainList.xml: Invalid file name: must contain only [a-z0-9_.]

[2011-11-10 10:21:04 - Testing] res\layout\PlaylistEditor.xml: Invalid file name: must contain only [a-z0-9_.]

[2011-11-10 10:21:04 - Testing] res\layout\PlaylistEditor.xml: Invalid file name: must contain only [a-z0-9_.]

The filenames do not have any invalid characters. Eclipse DOES save the project (including these files) so why does it throw this error message?

Answer 1

Your XML files can't contain upper-case characters in their names. Rename MainList.xml to mainlist.xml, etc. This is an Android requirement, not an Eclipse one.
