【问题描述】：

我创建了一个示例游戏，它可以在桌面上完美运行，但在 android 手机上会因以下错误而崩溃。

**Unfortunately, My LibGDX Game has stopped.**

我已经用两部不同的手机甚至模拟器进行了测试，但错误仍然是一样的。以下是 Android 版本的项目属性。

LogCat 是（带错误过滤器）：

【问题讨论】：

你能发布一个堆栈跟踪吗？
文件images/smountains.png在哪里？
打包“文件”以供 Android 应用程序在运行时访问有点棘手。您需要指定您尝试将其放置的位置，并将代码发布到您告诉 Libgdx 尝试使用它的位置。
显示加载images/smountains.png的行并显示文件在你的android项目中的位置。
它位于./assets/images/，访问的行是sMountainTexture=new Texture(Gdx.files.internal("images/smountains.png"));

【解决方案1】：

谢谢大家:) 问题已解决。其实文件名是

“smountains.PNG”

在主 libgdx 项目中，我使用了带有

的语法

sMountainTexture=new Texture(Gdx.files.internal("images/smountains.png"));

“png”和“PNG”大小写的区别在桌面项目中无关紧要，但在 Android 版本中被视为错误。再次感谢大家的帮助。
