Android的libGDX动画 [英] libGDX animation for android
本文介绍了Android的libGDX动画的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
如果我启动桌面，它运行的很不错，但在导出后，我的Android它崩溃后，我开始应用程序。
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。
它适用于桌面，但不适用于我的Android？
What's wrong that it works for the Desktop but not for my Android?

我在Java
中很新，所以我希望它是正确的部分：x
I'm pretty new in Java so I hope it's the right part :x
推荐答案
有些人有例外e logcat说：
There has been some persons with exceptions where the logcat says:
GdxRuntimeException: Libgdx requires OpenGL ES 2.0
这是由于您的模拟器不使用您的gpu的图形，最好的解决方案是使用您的手机测试您的应用程序，但如果由于任何原因您不能可以作为@AngelAngel应用此解决方案： libgdx android在启动时失败。
由于某种原因（可能opengl不会出现错误），以下错误的解决方案也可能会帮助您
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
如果只有在Windows上进行实验时，可能是因为您的某个资产与您在代码上使用的名称不完全相符。 Unix是case感觉，所以image.jpg不同于Image.jpg。所以请查看每个资产的名称是否匹配！
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!
