Libgdx FileHandle list() method doesn't work in jar file

Question

I created a desktop game in eclipse using Libgdx. The game runs great in eclipse, however the FileHandle list() method doesn't work when exported to a jar file. I used the following lines of code:

songFiles = Gdx.files.internal("./bin/" + "songs/").list();
System.out.println(songFiles[0]);

Again, in eclipse it prints the file location.However when exported to a jar, I get a java.lang.ArrayIndexOutOfBoundsException: 0 error.

Cannot export default Java libGDX project as a jar from Eclipse looks similar to the issue that I am having

Answer 1

It says you created the list or array but u didn't initialize it with length. That's why you have 0 at the end of error message.

Answer 2

由于list（）方法不能在桌面应用程序上使用，因此我将通过将歌曲目录中的文件名读写到文本文件来解决此问题。
