I know this post is super old, but if anyone comes looking, this problem has been fixed in ADT revision 17+ . Any services or Activities declare the namespace as:
xmlns:custom="http://schemas.android.com/apk/res-auto"
res-auto will be replaced at build time with the actual project package, so make sure you set up your attribute names to avoid collisions if at all possible.
