なんらかの理由でAndroidアプリが起動しません。それは本当に基本的なアプリです。実行すると、閉じる必要があると表示され、強制的に閉じるを押します。

import com.actionbarsherlock.app.ActionBar.Tab;
import com.actionbarsherlock.app.ActionBar.TabListener;
import com.actionbarsherlock.app.*;
import com.actionbarsherlock.app.SherlockActivity;
import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.SherlockFragmentActivity;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.util.Log;


public class MainActivity extends SherlockFragmentActivity implements TabListener{

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final ActionBar actionBar = getSupportActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        Tab tabRed = actionBar.newTab();
        tabRed.setText("Red Side");
      //  tabRed.setTabListener(new TabListener<TabFragment>(this, "tab1", TabFragment.class));
        Tab tabBlue = actionBar.newTab();
        tabBlue.setText("Blue Side");
       // tabBlue.setTabListener(new TabListener<TabFragment>(this, tabBlue, TabFragment.class));

        actionBar.addTab(tabRed);
        actionBar.addTab(tabBlue);


    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        Log.d("Main Activity", "tab " + String.valueOf(tab.getPosition()) + " clicked");

    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        Log.d("Main Activity", "tab " + String.valueOf(tab.getPosition())+ " un-clicked");

    }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) {
        Log.d("Main Activity", "tab " + String.valueOf(tab.getPosition()) + " re-clicked");


    }



}

これは私activity_main.xmlのですが、テキストが含まれています。xmlでもアクションバーを設定する必要がありますか？

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >



     <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/hello_world" />

</RelativeLayout>

各タブには、たとえば次のようなTabListenerが必要です。

Tab tabRed = actionBar.newTab();
tabRed.setText("Red Side");
tabRed.setTabListener(this);
actionBar.addTab(tabRed);

// The same is true for tabBlue
