加載在背景 - AndEngine GLES2

Question

IM移植我在AndEngine GLES2項目，GLES1 versione我用這個tutorial加載資產的背景下，現在我收到此錯誤：

mActivity.onCreateScene failed. @(Thread: 'GLThread 10') 
java.lang.ExceptionInInitializerError 

這是我onCreateScene方法

@Override 
    public Scene onCreateScene() { 
     this.mEngine.registerUpdateHandler(new FPSLogger()); 
     SplashScene mSplashScene = new SplashScene(this); 

     IAsyncCallback callback = new IAsyncCallback() { 

      @Override 
      public void workToDo() { 
      //Do something} 

      @Override 
      public void onComplete() { 
       LoadingScene mLoadingScene = new LoadingScene(mActivity.this); 
       mActivity.this.getEngine().setScene(mLoadingScene); 
      } 
     }; 

     new AsyncTaskLoader().execute(callback); 

     return mSplashScene; 
    } 

Answer 1

變化

new AsyncTaskLoader().execute(callback); 

到

//Fixed variant working with gles1 and gles2 
    runOnUiThread(new Runnable() { 
     @Override 
     public void run() { 
      new AsyncTaskLoader().execute(callback); 
     } 
    });
