i have 4 tabs on my main screen,

main ( set to current ) , Call, Email, Web

When a user clicks on any of tab call, email or web, it starts making a call, or go to compose a email, or opens up the browser respectfully.

Problem is, i want just three tabs (Call, Email, Web) and i Dont want any tab to be selected by default, means they should only become active when a user Touch them..(a call or any service cant be main at all)

All java coding, XML file, and Manifest code is given below,
