Android Studio unexpected top-level exception in libGDX project

Question

I have a fresh libGDX project, with gives above error message when try to build it.

Error:Execution failed for task ':android:dexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    D:\SDK_2015\build-tools\21.1.2\dx.bat --dex --no-optimize --output C:\Users\Ákos\Downloads\physics\android\build\intermediates\dex\debug --input-list=C:\Users\Ákos\Downloads\physics\android\build\intermediates\tmp\dex\debug\inputList.txt
Error Code:
    1
Output:
    UNEXPECTED TOP-LEVEL EXCEPTION:
    java.lang.RuntimeException: C:\Users\Ă?kos\Downloads\physics\android\build\intermediates\classes\debug: file not found

It is strange, I have never seen similar to this. What can causes this? I am using the most recent 1.2 version of Android Studio.

Answer 1

Can suggest you to try several things:

1. On the path C:\Users\Ákos\Downloads... is this symbol Á, possibly not recognized by IDE. Also on second path as well. Try to avoid any of non-ASCII characters.

2. On the path C:\Users\Ă?kos\Downloads\physics\android\build\intermediates\classes\ remove folder classes. Then clean and rebuild project.

But in my opinion and experience and as other answers said this is because of symbols.
