Eu estou seguindoest tutorial sobre libgdx. O que estou tentando fazer é carregar uma textura de uma cópia do badlogic.jpg (a cópia é chamada 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();
    }
...

O que eu recebo é a falha do aplicativo e "com.badlogic.gdx.utils.GdxRuntimeException: não foi possível carregar os dados do arquivo / wawa.jpg" na depuração:
