http://schemas.android.com/apk/res/android where does this URL point...?

Question

I am not getting where is url: http://schemas.android.com/apk/res/android ? Can somebody please let me know where does this point to? Why cannot we access this URL mentioned in xmlns:android namespace for android xml ?

Answer 1

You can't access it as it's a URI not a URL, the difference is well explained here :

Uniform Resource Identifier (URI)

A Uniform Resource Identifier (URI) is a string of characters which identifies an Internet Resource.

The most common URI is the Uniform Resource Locator (URL) which identifies an Internet domain address. Another, not so common type of URI is the Universal Resource Name (URN).

So, in some cases you might be able to access it and it'll probably have the description of the namespace.
