[使用DaoMaster.DevOpenHelper帮助程序时=新的DaoMaster.DevOpenHelper（此，“ notes-db”，null），显示错误，无法解析DaoMaster。怎么了？

我参加聚会有点晚，但是您需要至少有一个@Entity类，GreenDao才能生成类似DaoMaster和DaoSession的类。

因此，只需创建一个用@Entity和所需属性注释的类，然后单击Build->在AndroidStudio中进行构建或Build->在IntelliJ中进行清洁构建。您也可以单击AndroidStudio或IntelliJ右侧的Gradle选项卡，查找GreenDao Gradle任务并运行它。
