问题
I have the following problem
InputStream input = FileHandle.class.getResourceAsStream("/data/sounds/back.ogg");
returns null, but
InputStream input = FileHandle.class.getResourceAsStream("/data/sounds/back.png");
returns InputStream, also both files are in this folder. What can be wrong?
I'm using libgdx-0.9.6
回答1:
If your path starts with "/", java will search your file in the root of your file system.
If it is in your root folder, first of all, check if file exists:
ls -l /data/sounds/ | grep "back.ogg"
If it does not exists or you do not have permissions, then you have the answer.
If it exists, you could try another way to get its InputStream:
InputStream is = new FileInputStream("/data/sounds/back.ogg");
