title: GdxRuntimeException: Couldn't load file
body: <p>I am following <a href="http://code.google.com/p/libgdx/wiki/HelloWorld" rel="nofollow">this</a> tutorial on libgdx. What i am trying to do is loading a texture from a copy of badlogic.jpg (copy is called wawa.jpg):</p>
  
  <pre><code>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();
      }
  ...
  </code></pre>
  
  <p>What i get is the crash of application and "com.badlogic.gdx.utils.GdxRuntimeException: Couldn't load file data/wawa.jpg" in debug:</p>
