我这样操作数据库，要抛出Room cannot verify the data integrity. Looks like you've changed schema but forgot to update the version number. You can simply fix this by increasing the version number.这个异常。难道这个框架只能初始化一个类在AppDatabase 里面吗？可以qq联系你吗沟通一下这个心数据库的用法，我网上查了很多资料，都没发现什么原因导致的，有的说是数据库更新。感觉不是那么回事啊

找到原因了，原来数据库文件保存到sd卡根目录里面，没删除，我卸载后也删除不了，所以一直用的第一次初始化那个表的数据库，需要手动删除才行。
