insert initial data to sql lite android

Question

I\'m developing an expense tracker where I want to populate the DB with a few records when the application first start. I tried to call the method in my splash activity and add

Answer 1

private final String SAMPLE_DB_NAME = "TheftData";
    private final String SAMPLE_TABLE_NAME = "UserDetails";
    String CreateTable = "CREATE TABLE IF NOT EXISTS " +
            SAMPLE_TABLE_NAME +
            " (Username VARCHAR, Password VARCHAR," +                   
            " );";

Then in onCreate

protected void onCreate(Bundle savedInstanceState) {
try {
        sampleDB =  this.openOrCreateDatabase(SAMPLE_DB_NAME, MODE_PRIVATE, null);

        sampleDB.execSQL(CreateTable);
        sampleDB.close();
        }

    catch(Exception e)
    {Toast.makeText(getApplicationContext(), " Error: "+e.getMessage(), Toast.LENGTH_LONG).show();
    sampleDB.close();
    }

and to add data

 public void insertData(String username,String password)
    {

        sampleDB =  this.openOrCreateDatabase(SAMPLE_DB_NAME, MODE_PRIVATE, null);

        sampleDB.execSQL(CreateTable);
        sampleDB.execSQL("INSERT INTO " +
                SAMPLE_TABLE_NAME +
                " Values ('"+username+"','"+ password+"');");
        sampleDB.close();

    }
