            finish();
        LocalActivityManager manager = getLocalActivityManager();
  manager.destroyActivity(stack.pop(), true);
if (stack.size() > 0) {
Intent lastIntent = manager.getActivity(stack.peek()).getIntent();

spec.setContent(intent);

tabHost.addTab(spec);

Intent intent1 = new Intent().setClass(this, ActivityStack.class);
TabHost.TabSpec spec1 = tabHost.newTabSpec("tabId").setIndicator("Temp", getResources().getDrawable(R.drawable.invoice));
