[android] connessione background

[Maxton]

Salve a tutti, è un paio di giorni che non riesco a risolvere il mio dilemma, vorrei che per ogni tab della mia applicazione partisse un'intent diverso che si connetta a internet e cominci a mandare dati ad un server, non so come sviluppare l'intent e come inserirlo purtroppo, mi potete aiutare?

l'activity per ora è vuota e la classe per connettersi si chiama "Connessione()" e non richiede di passargli dati

public class MainActivity extends FragmentActivity implements ActionBar.TabListener
{
 
                SectionsPagerAdapter mSectionsPagerAdapter;
                ViewPager mViewPager;
 
                @Override
                protected void onCreate(Bundle savedInstanceState) 
                {
                               super.onCreate(savedInstanceState);
                               setContentView(R.layout.activity_main);
 
                               final ActionBar actionBar = getActionBar();
                               actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
 
                               mSectionsPagerAdapter = new SectionsPagerAdapter(
                                                               getSupportFragmentManager());
 
                               mViewPager = (ViewPager) findViewById(R.id.pager);
                               mViewPager.setAdapter(mSectionsPagerAdapter);
                              
                               mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener()
