In xml Header this is ?xml version="1.0" the xml VERSION you are defining. This is the ENCODING TYPE of xml to be defined encoding="utf-8"? . And this is the NAMESPACE of xml xmlns:android="http://schemas.android.com/apk/res/android" hope this help.

I assume you are talking about

<?xml version="1.0" encoding="UTF-8"?>

http://www.w3schools.com/xml/xml_tree.asp

Quoting from the link above

The first line is the XML declaration. It defines the XML version (1.0).

Also check

http://en.wikipedia.org/wiki/UTF-8

<LinearLayout xmlns:android="schemas.android.com/apk/res/android";

Its a LinearLayout that you have in xml

xmlns- its xml name space

A quick search on the same topic on stackoverflow gives the below links which should anser your question

Why this line xmlns:android="http://schemas.android.com/apk/res/android" must be the first in the layout xml file?

What does "xmlns" in XML mean?

I think you are talking about this line <?xml version="1.0" encoding="utf-8"?>

That line actually defines the version of .xml file.

Please refer to XML Standards
