ListView Abrir nueva actividad

Question

Acabo de crear esta lista de lististas y algunas actividades que deben comenzar al hacer clic en uno de los elementos de ListView.Cuando haga clic en el primer elemento de ListView, debe iniciar "Abactividad", en lugar de comenzar la actividad, la aplicación se bloquea.¿Alguien puede decirme cómo solucionar este problema?

Aquí está mi archivo principal:

package pcsalt.example.customlistviewdemo;

import java.util.ArrayList;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.TextView;


public class MainActivity extends Activity  {

ListView lvDetail;
Context context = MainActivity.this;
ArrayList<ListData> myList = new ArrayList<ListData>();

String[] title = new String[] {
        "Above & Beyond", "Afrojack", "DJ 3", "DJ 4",
        "DJ 5", "DJ 6", "DJ 7", "DJ 8"
};
String[] desc  = new String[] {
        "56:58", "58:49", "60:00", "60:00",
        "60:00", "60:00", "60:00", "60:00"
};
int[]    img   = new int[]    {
        R.drawable.star3, R.drawable.star3, R.drawable.star3, R.drawable.star3,
        R.drawable.star3, R.drawable.star3, R.drawable.star3, R.drawable.star8
};

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


    lvDetail = (ListView) findViewById(R.id.lvCustomList);
    // insert data into the list before setting the adapter
    // otherwise it will generate NullPointerException  - Obviously
    getDataInList();
    lvDetail.setAdapter(new MyBaseAdapter(context, myList));
}

private void getDataInList() {
    for(int i=0;i<8;i++) {
        // Create a new object for each list item
        ListData ld = new ListData();
        ld.setTitle(title[i]);
        ld.setDescription(desc[i]);
        ld.setImgResId(img[i]);
        // Add this object into the ArrayList myList
        myList.add(ld);
    }
    lvDetail.setOnItemClickListener(new OnItemClickListener() 
    {
        @Override
        public void onItemClick(AdapterView<?> a, View v, int position, long id) 
        {
             // In the following line "v" refers to the View returned by the `getView()` method; meaning the clicked View.
             TextView txtName = (TextView)v.findViewById(R.id.lvCustomList);
             String name = txtName.getText().toString();
             switch(name)
             {
                  case "Above & Beyond":
                      Intent intent = new Intent(MainActivity.this, ABActivity.class);
                      startActivity(intent);
                      break;

                  case "Afrojack":
                       Intent intent1 = new Intent(MainActivity.this, AfrojackActivity.class);
                       startActivity(intent1);
                       break;

                  //And so on and so forth....
             }

        }
    });

gracias.

Agregue estas actividades para manifestar como

<activity android:name=".ABActivity" />
<activity android:name=".AfrojackActivity" />
