Error when installing android application

Question

I trying to use C2DM in my android application, but after I added it I can't install the application. I get this error "Installation error: INSTALL_PARSE_FAILED_MANIFEST_MALFORMED". But I can't see whats wrong.

Anyone that know what I have done wrong?

Answer 1

I finally found whats wrong, the package name on the application was not allowed to start with capital letter.
