simplest way create app swiping functionality in opinion create new android application via eclipse wizard following options selected:

1. create activity -> blankactivity
2. navigation type = tabs + swipe

this create application (i think) 3 pages can swipe through. can check created files/code , change whatever want/need to.

and mentioned in comments answer, isn't possible activites, need use fragments!
