XML canonicalization is often used when there is need to create digital signature to be sent to peers for verification. Since digital signature is created based on XML data, the XML data has to be canonicalized before its signature value can be calculated. Even an extra space may affect the signature value calculated, hence it must follow some rules to canonicalize the XML data so that it has a standard format. This is why W3C created specification Canonical XML Version 1.1.This specification provides the rules to format element nodes, attribute nodes and namespace nodes etc. Different pr...

This tutorial assumes that you already have an activity and are using an XML layout.Open the layout XML and add the button element.  Assign an ID with the “@+id” operator.  The + tells Android to generate an ID for this element so that you can reference it in your Java files.This is an example.

Nearly all generated XML I’ve seen sucks badly. I think this is because XML cannot efficiently represent common data structures found in programming languages.XML is good for representing trees. If you imagine the outline of a document, you see that this is definitly a tree....
