Here is my code

public class DataBaseHelper extends SQLiteOpenHelper{
 //The Android's default system path of your application database.

    public static String DB_PATH;

    public static String DB_NAME;
    public SQLiteDatabase database;
    public final Context context;
    public static String TABLE_NAME="pincode";

    public SQLiteDatabase getDb() {
        return database;
    }

    public DataBaseHelper(Context context, String databaseName) {
        super(context, databaseName, null, 3);
        this.context = context;

        String packageName = context.getPackageName();
        DB_PATH = String.format("//data//data//%s//databases//", packageName);
        DB_NAME = "pinnew1.sqlite";
        openDataBase();
    }


    public void createDataBase() {
        boolean dbExist = checkDataBase();
        if (!dbExist) {
            this.getReadableDatabase();
            try {
                copyDataBase();
            } catch (IOException e) {
                Log.e(this.getClass().toString(), "Copying error");
                throw new Error("Error copying database!");
            }
        } else {
            Log.i(this.getClass().toString(), "Database already exists");
        }
    }

        } catch (SQLException e) {
            Log.e(this.getClass().toString(), "Error while checking db");
        }
