Failed to package contents

EDIT: for some reason my empty lines are not staying

Hi there,

I have been building my android game fine for weeks and then all of a sudden i get this error saying Failed to Re-package contents.

Has anyone ha this happen before i have read online about making sure i have API level 14 installed for android and i do.

Here is the full error. I literally have no idea what has happened and this was the final build (just moving some gui) for a client and then this.

Error building Player: CommandInvokationFailure: Failed to re-package resources. See the Console for details.

Fixed the problem, Turns out i was using an xml that was older than the sdk as i copied a news xml file from one of my other games and it all worked. I have no idea how it actually fixed but it did.
