Hi NewUser,

Thanks for posting on the forum! Every application that developers submit to Appstore must have a unique package name, which serves as an identifier for an application. It is most often in a format such as com.CompanyName.ProductName and developers are advised to use reverse domain names for their applications.

"To avoid conflicts with other developers, you should use Internet domain ownership as the basis for your package names (in reverse). For example, applications published by Google start with com.google. You should also never use the com.example namespace when publishing your applications." (https://developer.android.com/guide/topics/manifest/manifest-element.html#package)
