Loading tables into Sqlite database

I need to know how to insert by default (when you load the app for the first time you find this data) data into my sqlite db, by example

gameidno:1 gamedate:30/11/2014 gameteam:Spurs

gameopponent: LAL

gameidno:2

gamedate:05/12/2014

gameteam:Spurs

gameopponent: Mavs

gameidno:3

gamedate:09/12/2014

gameteam:Spurs

gameopponent: Memphis

Here is my DBhelper:

 public void onCreate(SQLiteDatabase db) {

    db.execSQL("CREATE TABLE if not exists gamestable(id INTEGER PRIMARY KEY AUTOINCREMENT,"

            + "gameidno"

            + " INTEGER,"

            + "gamedate"

            + " TEXT,"

            + "gameteam"

            + " TEXT,"

            + "gameopponent" + " TEXT)");

}



@Override

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

    db.execSQL("DROP TABLE IF EXISTS" + gamestable);

    onCreate(db);

}



public void addGame(GameModel gameitem) {

    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues contentValues = new ContentValues();





    contentValues.put("gameidno", gameitem.gameidno);

    contentValues.put("gamedate", gameitem.gamedate );

    contentValues.put("gameteam", gameitem.gameteam);

    contentValues.put("gameopponent", gameitem.gameopponent);

    db.insert("gamestable", null, contentValues);



    db.close();

}

public class AddGames extends Activity implements OnClickListener {



    private Button btn_addrecord;

    private EditText txtpname;

    DatabaseHelper db;

    GameModel pm;

    private Spinner gamesSpinner;

    private Spinner timeSpinner;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        // TODO Auto-generated method stub

        super.onCreate(savedInstanceState);

        setContentView(R.layout.add_reminder);



        txtpname = (EditText) findViewById(R.id.myEditText);



        gamesSpinner = (Spinner) findViewById(R.id.games_spinner);  

        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,

                R.array.reminders_list, android.R.layout.simple_spinner_item);

        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        gamesSpinner.setAdapter(adapter);





        timeSpinner = (Spinner) findViewById(R.id.time_spinner);    

        ArrayAdapter<CharSequence> adapter1 = ArrayAdapter.createFromResource(this,

                R.array.time_list, android.R.layout.simple_spinner_item);

        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        timeSpinner.setAdapter(adapter1); 





        btn_addrecord = (Button) findViewById(R.id.button1);

        btn_addrecord.setOnClickListener(this);



    }



    @Override

    public void onClick(View v) {

         DatabaseHelper db;

         ProductModel pm;



        // TODO Auto-generated method stub

        switch (v.getId()) {

        case R.id.button1:



            if (txtpname.getText().toString().equals("")

                    || gamesSpinner.getSelectedItem().toString().equals("")) {

                Toast.makeText(AddGames.this, "Please add values..",

                        Toast.LENGTH_LONG).show();

            } else {

                pm = new GamesModel();

                pm.idno = (txtpname.getText().toString());

                pm.gamename = gameSpinner.getSelectedItem().toString();

                pm.reminderway = timeSpinner.getSelectedItem().toString();



                Log.i("gameidno,gamename,productprice", "" + pm.idno + ""

                        + pm.gamename + "" + pm.reminderway);

                   db.addGame(pm);

                Toast.makeText(Addgame.this, "Record Added successfully.",

                        Toast.LENGTH_LONG).show();

                finish(); 

            }

            break;



        default:
