I am having issues @ run with this code: App Force Closing..

Sprinter.Java

import android.app.ListActivity;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.widget.ListAdapter;
import android.widget.SimpleCursorAdapter;

public class Sprinter extends ListActivity {
    /** Called when the activity is first created. */
    final static String MY_DB_NAME = "Sprinter"; 
    final static String MY_DB_TABLE = "Stations"; 

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

    SQLiteDatabase myDB = null; 
    try { 
         myDB = this.openOrCreateDatabase(MY_DB_NAME, MODE_PRIVATE, null); 

         myDB.execSQL("CREATE TABLE IF NOT EXISTS " + MY_DB_TABLE + "_id integer primary key autoincrement, name varchar(100);"); 

         myDB.execSQL("INSERT INTO " + MY_DB_TABLE + " (_id, name)" + " VALUES ('', 'Oceanside Transit Center');"); 

         myDB.execSQL("INSERT INTO " + MY_DB_TABLE + " (_id, name)" + " VALUES ('', 'Coast Highway');"); 

         Cursor mCursor = myDB.rawQuery("SELECT name" + " FROM " + MY_DB_TABLE, null); 

         startManagingCursor(mCursor); 

         ListAdapter adapter = new SimpleCursorAdapter(this, R.layout.list_item, mCursor, new String[] { "name" }, new int[] { R.id.Name }); 

         this.setListAdapter(adapter); 

         this.getListView().setTextFilterEnabled(true); 
       } finally { 
         if (myDB != null) { 
              myDB.close(); 
         } 
       } 
   }     
}
