Intent inte = new Intent(TabsActivity.this, PhotosActivity.class);
inte.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
spec1.setContent(inte);


TabSpec spec2 = tabHost.newTabSpec("tabtwo");
spec2.setIndicator(createTabView(tabHost.getContext(), "tabtwo", R.drawable.tab_account));
Intent _int = new Intent(TabsActivity.this, TabTwoActivity.class);

    public class TabTwoActivity extends TabActivity {

   TabSpec spec1 = tabHostacc.newTabSpec("tabone");
spec1.setIndicator(createTabView(tabHostacc.getContext(), "tabone", R.drawable.tab_home));
Intent inte = new Intent(TabTwoActivity .this,  yourfirstActivity.class);
inte.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
spec1.setContent(inte);      

TabSpec spec2 = tabHostacc.newTabSpec("tabtwo");
