Libgdx游戏在Android手机上崩溃

Question

我创建了一个在桌面上完美运行但在Android手机上崩溃并出现以下错误的示例游戏。

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

我已经使用两种不同的手机甚至模拟器进行了测试，但错误仍然相同。以下是Android版本的项目属性。

Answer 1

谢谢大家:)问题解决了。实际上文件名是

  

“smountains.PNG”

在主libgdx项目中，我使用

语法

  

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

案例“png”和“PNG”的区别在Desktop Project的情况下无关紧要，但在Android版本中被视为错误。再次感谢每个人的帮助。
