Are Android app domain names different from uniquely identifying an app?

Question

I am starting my first Android application, and after reading it I understand that it requires the reverse domain name required for the Android application to uniquely identify the application, but is it the application domain name used for something other than uniquely identifying the application?

In particular, I am interested in

1) Consequences (function or error?) Of using different domain names for actions in the application

2) Is there any relation to the registered domain used for the website?

3) Any other snippets to fill my flaws :)

Answer 1

Sun recommends that you use your company's domain name on the Internet (which is known to be unique), written in reverse order. Then you use subpackages for different projects. For example, horstmann.com is a domain registered by one of the authors. Written in reverse order, it turns into the com.horstmann package. This package can then be subdivided into subpackages such as com.horstmann.corejava.

From redesigned and updated Java SE 6. Core Java.

These are all java packages. Android is no different.

Sorry if this does not answer all your questions, but I think the answer is more likely a general Java question than a specific android question. This is a pretty good explanation.
