The application crashes when creating a tab

There is a TabHost in which there are several tabs, they are located below, each tab is a separate activation. In one activity I try to add an actionbar with tabs, but the application crashes just by creating a tab. activity code

public class Restaurant extends Activity implements TabListener { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.restaurant); ActionBar bar = getActionBar(); //bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); Tab tab = bar.newTab(); tab.setText("tab1"); tab.setTabListener(this); bar.addTab(tab); tab = bar.newTab(); tab.setText("tab2"); tab.setTabListener(this); bar.addTab(tab); } 

Error log:
