One of the app markets I submitted my app to, denied my app for the following reason, I assume this means I have to change the package name. I tried doing this in my manifest.xml, but got compilation errors.
PACKAGE NAME: Per the Android Open Source Project and the SlideME developer agreement, your application should have an appropriate and unique package name (not to be confused with the uploaded .apk file name), as set in the Application Manifest (.xml). Package names that are too short, not unique, unchanged from tutorial examples, generic, use unauthorized trademarks, or are suspicious will result in the application being denied. Package names must follow the standard Android and Java practices for packageName nomenclature, i.e. companydomain.apptitle or companyname.apptitle or developer/authorname.apptitle. This helps to avoid conflicts as multiple apps cannot share the same packageName, it indicates ownership of the application to your account, and it indicates that this application was not built using tutorials/example source code.
