I have looked through numerous questions that are very similar to mine and have tried all the fixes that the other questions recommended to no avail. So I decided I'd post my own question in hopes that someone can help.

String url = newsItem.getNewsImageUrl();
ImageLoader imageLoader = new ImageLoader(activity, 600, R.mipmap.placeholder);
imageLoader.displayImage(url, image);
return view;
}
}
The error that I am getting has a comment next to it in the NewsActivity. It seems to be trying to cast an integer to a HashMap for some reason. I have multiple other classes that use this exact method and have no issue, but for this NewsActivity I am getting this error.
Any suggestions?
Thanks so much!
