We don't have MVC in android, but we can try these alternates:
We can set our user interface in different XML files by resolution, hardware, etc.
we can define our resources in different XML files by locale, etc.
We can spread classes like ListActivity, TabActivity and obtain the use of the XML file by inflaters.
we can create as many classes as we want for our business logic.
A lot of Utils have been previously written for us- DatabaseUtils, Html.
