java - 我的 Android 应用程序在模拟器上运行但无法在我的 Android 设备上运行

Question

我的应用程序在安卓模拟器上运行良好。当我试图在我的设备上运行它时，LogCat 列给我的信息是没有这样的列:USERNAME。 在模拟器上，我的 SQLite 数据库正常创建，我可以添加新用户并登录，但在我尝试执行此操作时，在设备中出现异常。

这是我尝试创建新用户时的日志文件:

有人可以帮忙吗？

Answer 1

您可能在没有增加 DATABASE_VERSION 的情况下更改了数据库架构，因此新应用正在寻找旧数据库。

static final int DATABASE_VERSION=2;

应该修复它。
