问题
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.
So my question...:
What's wrong that it works for the Desktop but not for my Android?

I'm pretty new in Java so I hope it's the right part :x
回答1:
There has been some persons with exceptions where the logcat says:
GdxRuntimeException: Libgdx requires OpenGL ES 2.0
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
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!
回答2:
you use emulator?
libgdx android failed on launch
EDIT:
Opetion
I tell you what, because I found a similar question, I put down the logcat that question, and send this response, and the user is solved by changing the file,. TTF by. ttf and spent some time looking for the error, why was saying what I find confusing the log, however I have no windows, but the most striking difference I see between the two is that this line log
11-28 21:10:37.617: D/libEGL(613): Emulator without GPU support detected. Fallback to software renderer. that the log of this question is not listed. perhaps when the error is emulation or lack of OpenGL is more like the logcat or the first and when the file not found by the difference between uppercase and lowercase log you is more like the second, which says Emulator detected without GPU support. I hope I completely understand my English is not good
