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

import com.nostra13.universalimageloader.core.ImageLoader;
import com.folder.folder.AbsListViewBaseActivity;

public class CollectionDemoActivity extends FragmentActivity{

    assignImageLoader newAssign;
    static AbsListViewBaseActivity absList;
    static ImageAdapter m3;

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

#16790176. check this example of UIL. might help – Burack

what's on line 448 CollectionDemoActivity.java? Also what is this method Oncreate() in CollectionDemoActivity.java? – Burack

@Burack I tried to see the answers and the codes, but I think is far from what I need. Maybe my need is a matter of extending another class manipulations to get the same flow from the orginal. Not sure though. Please help me with this sir. I been working with this one in two days. – Sickle

the error 488, imageLoader.displayImage(path, img, options); – Sickle

i am confused your adapter class has this newAssign.getImageLoader(Image Path, holder.image, options2) where is your view holder and options2 intialized. Your app flow is very confusing – Burack

sir, I added code above. Please see. newAssign.getImageLoader(Image Path, holder.image, options2) and imageLoader.displayImage(path, img, options) are the same I just tried to create another class just to experiment and see if extending the AbsListViewBaseActivity will work. – Sickle

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()));

Roana

Glad to help. Any time. :P – Roana

where should I implement it?? – Partisan

Incase you still don't know @Partisan you can implement this in the onCreateView – Aerology

@Roana ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(MyActivity.this)); this way is working for me. – Housekeeping

ImageLoader imageLoader =ImageLoader.getInstance(); imageLoader.init(ImageLoaderConfiguration.createDefault(ctx)); This will work ...!! – Leonidaleonidas

in fragment we can use like this ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(getActivity())); – Septennial

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());
}

Answer 3

This worked better for me.

Put the following in the onCreate of your activity

   ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(MyActivity.this));

Rives

Answer 4

Just put the following code in the BaseActivity or MyApplication class:

public ImageLoader getImageLoader() {

    if (mImageLoader == null) {
        mImageLoader = ImageLoader.getInstance();
        mImageLoader.init(ImageLoaderConfiguration.createDefault(this));
    }
    return this.mImageLoader;
}

Then whenever you want to use the image loader then create a new instance of ImageLoader, just like the following:

private ImageLoader imageLoader = MyApplication.getInstance().getImageLoader();

Or if you take BaseActivitiy enter code here:

private ImageLoader imageLoader = BaseActivity.getInstance().getImageLoader();

Answer 5

First, check that user imageLoader.jar packet is properly included in the project by going in project properties → Java build path.

Second, implement this code in the onCreateView

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

Titanium

What do you mean by "user imageLoader.jar packet"? – Leyla
