Error while connecting to the database

Hi,

i was getting some error while connecting the data base

Here is my code (maindb.java)

package com.example.db1;

import android.app.Activity;
import android.os.Bundle;
import android.database.sqlite.SQLiteDatabase;

public class maindb extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maindb);
SQLiteDatabase db;
db = openOrCreateDatabase("DataBase.db",
SQLiteDatabase.CREATE_IF_NECESSARY, null);
//do the task you want here
db.close();
}
}


do i need to do anything else. It would be great help for me if some one helps on this

Thanks in Advance
