title: Libgdx: AssetManager not loading assets
body: <p>Okey Im simply struggling with the AssetManager in libgdx. I´ve followed every tutorial, read every wikipage, but I cant get it to work.</p>
  
  <p>Asset class:</p>
  
  <pre><code>public class Assets {
  
  private static final AssetManager manager = new AssetManager();
  public static final String background = "data/lawn.png";
  public static void load() {
  
      manager.load(background, Texture.class);
  
  }
  public static void dispose()     {
      manager.dispose();
  }
  
  public static boolean update() {
      return manager.update();
  }
  </code></pre>
  
  <p>Main class:</p>
  
  <pre><code>public class TombStone extends Game implements Screen {
  @Override
  public void create () {
  
      Assets.manager.update();
  
  
  
  }
  </code></pre>
  
  <p>And I call my textures like this in a Screen class:</p>
  
  <pre><code>public class StoneScreen implements Screen{
  public Texture texture;
  public StoneScreen(TombStone gam){
  loadStandard();
  }
  public void loadStandard() {
  texture= Assets.manager.get(Assets.background, Texture.class);
  }
  </code></pre>
  
  <p>So when I run the app it crashes before showing anything giving me:
  "FATAL EXCEPTION: GLThread 32182" "Asset not loaded: assets/data/lawn.png"</p>
