        //完成Application的初始化
        application = this;
        createData();

    //操做数据库
    private void createData() {
        //第一步建立一个数据库
        DaoMaster.OpenHelper openHelper = new DaoMaster.DevOpenHelper(application, "stu.db");
        SQLiteDatabase sqLiteDatabase = openHelper.getWritableDatabase();
        //第二步用数据库框架来包装数据库
        DaoMaster daoMaster = new DaoMaster(sqLiteDatabase);
        //第三步生成Session对象
        mDaoSession = daoMaster.newSession();
    }

    public DaoSession getDaoSession() {
