【中文标题】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【英文标题】：My Android application runs on emulator but not working on my android device 【发布时间】：2017-07-03 01:27:47 【问题描述】：我的应用程序在 android 模拟器上运行良好。当我试图在我的设备上运行它时，LogCat 列给了我信息，表明没有这样的列：USERNAME。 在模拟器上，我的 SQLite 数据库已正常创建，我可以添加新用户并登录，但在设备中尝试执行此操作时出现异常。
这是我尝试创建新用户时的日志文件：

有人可以帮忙吗？
【问题讨论】：
DATABASE_CREATE 字符串在哪里使用？你能把它删掉吗？ 我在另一个名为 DataBaseHelper 的类中使用 DATABASE_CREATE String。正如我在模拟器上所说，一切正常。 显示那个助手类。 【参考方案1】：您可能在未增加 DATABASE_VERSION 的情况下更改了数据库架构，因此新应用正在查找旧数据库。
static final int DATABASE_VERSION=2;
应该修复它。
【讨论】：
数据库架构没有变化 @Adrian-Mazurkiewicz 您可能在将应用程序安装到手机后但在将其安装到模拟器之前的某个时间更改了该列的名称【参考方案2】：尝试在设备上卸载应用程序并重新运行它。
【讨论】：
其实有帮助 ;) 谢谢以上是关于我的 Android 应用程序在模拟器上运行，但无法在我的 android 设备上运行的主要内容，如果未能解决你的问题，请参考以下文章
React Native 在多个同时运行的 Android 模拟器上运行
为啥我的模拟器没有在 Android Studio 上运行？
android studio 不在 iso 模拟器上运行我的应用程序
