Apps Starting up

[Tactical-Taco]

Hey guys. I've been wanting to write apps for android for a while now. I know many web based languages but never really learned Java.
As I learn Java it's obvious to see that it's an easy language. However when I look at examples of Android apps I don't really see the similarities.
Could someone explain to me the relationship between Java and and the Android SDK?
Also, I really don't understand the XML involved for the interfaces. Isn't XML only used to transfer data and not display it?..
Thanks in advance.

The android SDK is a set of libraries and tools used in the development of an android application.

You say you know web languages? Have you never noticed the similarities between HTML and XML?
XML is a language to define structures. This can be used for data which has to be transfered between different applications but also for structure like in HTML and XAML.

The Developer's Guide | Android Developers
This is the developers guide which will teach you the basics of building android applications with the SDK.

Good luck and have fun.

thanks for the reply!
And yes I do see the similarities but I was always taught to use xml to transfer data..Even at that I never used it.. I'm into the backend of web building ( php and such) so I was never really into the actual designing...
thanks again!
