问题描述
如果我先干为桌面运行pretty的不错，但它崩溃出口为我以后的Android之后我启动应用程序。
If I start it for Desktop it runs pretty nice, but after the export for my Android it crashes right after I start the application.
所以我的问题...
什么是错的，它适用于桌面，但不是我的Android？
What's wrong that it works for the Desktop but not for my Android?

我是pretty的新Java中 所以我希望这是正确的部分：X
I'm pretty new in Java so I hope it's the right part :x
推荐答案
已经有一些人有例外，其中的logcat说：
There has been some persons with exceptions where the logcat says:
GdxRuntimeException: Libgdx requires OpenGL ES 2.0
这是因为你的模拟器不使用GPU进行图形和最好的解决办法是使用手机来测试你的应用程序，但如果因为任何原因，你不能，你可以为@AngelAngel应用该解决方案：的 libgdx Android的失败上推出。
出于某种原因（可能不是失灵了OpenGL）的解决方案，以下面的错误也可以帮助你。
This is due to your emulator not using your gpu for graphics and the best solution would be to use your phone to test your application but if for any reason you can't you can as @AngelAngel apply this solution: libgdx android failed on launch.
For some reason ( probably the opengl not glitching ) the solution to the following error might also help you
com.badlogic.gdx.utils.GdxRuntimeException: Error reading file: xxx.xxx
如果你有这样的误差仅在Android中尝试，而它在Windows上运行，它可能是因为你的资产之一，并不完全是你用你的code中的名称相匹配。 Unix的区分sensative所以image.jpg的是image.jpg的不同。因此，检查所有的资产，你必须看到，如果名称相匹配！
If you have this error only while experimenting in Android while it works on Windows it probably is because one of your assets doesn't exactly match the name you used on your code. Unix is case-sensative so image.jpg is different from Image.jpg . So check every asset you have to see if the names match!
