GdxRuntimeException: Couldn't load file

问题

I am following this tutorial on libgdx. What i am trying to do is loading a texture from a copy of badlogic.jpg (copy is called wawa.jpg):

public class HelloWorld implements ApplicationListener {
    SpriteBatch spriteBatch;
    Texture texture;
    Texture watched_texture;
    BitmapFont font;
    Vector2 textPosition = new Vector2(100, 100);
    Vector2 textDirection = new Vector2(5, 3);

    @Override
    public void create () {
        font = new BitmapFont();
        font.setColor(Color.RED);
        texture = new Texture(Gdx.files.internal("data/badlogic.jpg"));
        watched_texture = new Texture(Gdx.files.internal("data/wawa.jpg"));
        spriteBatch = new SpriteBatch();
    }
...

What i get is the crash of application and "com.badlogic.gdx.utils.GdxRuntimeException: Couldn't load file data/wawa.jpg" in debug:

Just can't figure out what's wrong.

回答1:

I also had the same problem, but my mistake was a file name error.

The file was called gameScreenshot.PNG, and I had put in the string as "gameScreenshot.png".

In Windows it accepted the file name fine, but on android it didn't work, so I had to rename it to "gameScreenshot.PNG"

回答2:

solved: i didn't put the new texture into the "assets" folder of android project
