                    if (tabId.equals(tabsTitles[i])) {

                // TODO Auto-generated method stub

            }

            @Override
            public void onPageScrollStateChanged(int arg0) {
                // TODO Auto-generated method stub

            }
        });

There was a issue in the adapter code

public Fragment getItem(int index) { 
    switch (index % 3) {
     case 2: // Top Rated fragment activity return
     new ProjectFragment(); 
    case 1: // Games fragment activity 
    return new RentFragment(); 
    case 0: // Movies fragment activity
     return new SellFragment();
     } return null; 
    }
