问题描述

如果我为桌面启动它，它运行得很好，但是为我的Android导出后，它在我启动该应用程序后立即崩溃。

所以我的问题...：

它适用于台式机而不适用于我的Android，这是什么问题？

您使用模拟器吗？

libgdx android启动失败

编辑：

行动

我告诉你什么，因为我发现了一个类似的问题，所以我记下了该问题的日志记录，并发送此响应，并且通过更改文件解决了用户。 TTF通过。 ttf并花了一些时间寻找错误，为什么要说让我感到困惑的日志，但是我没有窗口，但是我看到的两者之间最显着的区别是该行日志11-28 21:10:37.617: D/libEGL(613): Emulator without GPU support detected. Fallback to software renderer. 11-28 21:10:37.617: D/libEGL(613): Emulator without GPU support detected. Fallback to software renderer. 该问题的日志未列出。 也许当错误是仿真或缺少OpenGL时更像logcat或第一个，而当由于大写和小写日志之间的差异而找不到文件时，您更像第二个，这表明仿真器在没有GPU支持的情况下被检测到。 我希望我完全理解我的英语不好

有一些人例外，logcat说： 

GdxRuntimeException: Libgdx requires OpenGL ES 2.0

这是由于您的仿真器未将gpu用于图形处理，最好的解决方案是使用手机测试您的应用程序，但是如果由于某种原因您无法使用@AngelAngel，则可以应用此解决方案： libgdx android启动失败 。
由于某些原因（可能是opengl不能出错），针对以下错误的解决方案也可能对您有所帮助 

 com.badlogic.gdx.utils.GdxRuntimeException: Error reading file: xxx.xxx

如果只有在Windows下可以在Android上进行实验时才遇到此错误，则可能是因为您的资产之一与您在代码中使用的名称不完全匹配。 Unix区分大小写，因此image.jpg与Image.jpg不同。 因此，请检查每个资产，以查看名称是否匹配！
