Android - ImageLoader must be init with configuration before using in UIL

Question

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

Basing from this Approach:

ImageGallery

Answer 1

Try to implement this inside your onCreateView:

For Activity -

BaseActivity.imageLoader.init(ImageLoaderConfiguration.createDefault(getBaseCont‌​ext())); 

For Fragment -

ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(getActivity())); 

Answer 2

I think you are using the Universal image loader API. If yes, then you have forgot to configure the image loader in the Application class.

Add the below function in your Application class:

public static void initImageLoader(Context context) {      // This configuration tuning is custom. You can tune every option, you may tune some of them,     // or you can create default configuration by the     //  ImageLoaderConfiguration.createDefault(this);     // method.     //     ImageLoaderConfiguration.Builder config = new ImageLoaderConfiguration.Builder(context);     config.threadPriority(Thread.NORM_PRIORITY - 2);     config.denyCacheImageMultipleSizesInMemory();     config.diskCacheFileNameGenerator(new Md5FileNameGenerator());     config.diskCacheSize(50 * 1024 * 1024); // 50 MiB     config.tasksProcessingOrder(QueueProcessingType.LIFO);     config.writeDebugLogs(); // Remove for release app      // Initialize ImageLoader with configuration.     ImageLoader.getInstance().init(config.build()); }
