我已经下载的一者ImageDownloader code从GitHub上（从这里） 现在，当我想从我的web下载图像我收到此运行时异常ImageLoader的必须用配置使用前初始化。

I have downloaded one ImageDownloader code from gitHub(from Here) Now when i am trying to download the image from my webservice i am getting this Runtime Exception "ImageLoader must be init with configuration before using".

我不能够计算出来... PLZ帮助....

I am not able to figure it out... Plz help....

和我这个适配器::
