Android - ImageLoader must be init with configuration before using in UIL
I got the error:
ImageLoader must be init with configuration before using is the error from Illegal State Exception.
I am struggling to display the images in my approach of putting the gridview inside a fragments. As for my understanding the imageLoader should be initialized first by extending the class AbsListViewBaseActivity which will be extending BaseActivity.
These two classes are used to initialize the imageLoader. I pretty messed up with the flow, and I am getting errors in runtime and been working with this in two days. I'll include LogCat errors.
My own version
--Main Class

assignImageLoader newAssign;
static AbsListViewBaseActivity absList;
static ImageAdapter m3;
Oncreate()
{
newAssign = assignImageLoader;
m3 = ImageAdapter();
((GridView) absList.listView).setAdapter(m3);
}
}

Basing from this Approach:
Answer
Try to implement this inside your onCreateView:
For Activity -
BaseActivity.imageLoader.init(ImageLoaderConfiguration.createDefault(getBaseContext()));
For Fragment -
ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(getActivity()));
