Runtime error corona应用程序的运行时错误

我制作了一个非常简单的应用程序，具有一些简单的功能，它在corona模拟器上运行得非常好，如屏幕截图所示，但当我构建APK文件时，我在手机上打开应用程序时出现了以下错误：“c:\Users\Moamen\Documents\corona projects\Learning\main.lua:36:尝试索引全局“an”（一个零值）

这是应用程序错误：

Android区分大小写，但Windows（通常）不区分大小写。因此，将

bg.JPG

替换为

bg.JPG

，并相应地重命名文件

注:

• 使用小写字母作为文件名
• 尽可能使用局部变量，例如

  local an=display.newImage（“bg.jpg”，150250）

欢迎使用堆栈溢出！请添加图像而不是链接。这一次我已经为您完成了这项工作-请参阅以获取有关格式设置的更多信息。
