[android-developers] Re: Need Help to Develope my first Android Project.

That will be a horrible collage (http://www.google.com/search?q=define
%3Acollage)

Read this whole guide: http://developer.android.com/intl/de/guide/index.html
If that is too hard, then consider buying a book.

PS: Java programming language knowledge is mandatory!
