Android : using universal image loader for listview

I am using universal image loader to cash images from a url in a listview. There is an exception as below: My code to define imageloader:

ImageLoader imageloader;

imageloader.getInstance().init(ImageLoaderConfiguration.createDefault(getApplicationContext()));

My code to use a handler for image view:

holder.pic_path= (ImageView) findViewById(R.id.song_pic); imageloader.displayImage(pic_path[position], holder.pic_path);

My code to display image from url:

imageloader.displayImage(pic_path[position], holder.pic_path);

pic_path[position] is an array of urls.

And exception:
