How to use "Android-Universal-Image-Loader"

I want to gridview and listview using Android-Universal-Image-Loader.

https://github.com/nostra13/Android-Universal-Image-Loader

I downloaded and modified it.

it works fine, however when I change and move the source to another project, it's crashed.

I don't know why :(

there is no error and any error messages.

I think it's null point error or initiate library.

I think error will comes with this part.

listView = (GridView) findViewById(R.id.gridview);
((GridView) listView).setAdapter(new ImageAdapter());


and

public class ImageAdapter extends BaseAdapter {
@Override
public int getCount() {
Log.v("OWL","TEST1");
return imageUrls.length;
}

@Override
public Object getItem(int position) {
Log.v("OWL","TEST2");
return null;
}

@Override
public long getItemId(int position) {
Log.v("OWL","TEST3");
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
Log.v("OWL","TEST4");
final ImageView imageView;
if (convertView == null) {
imageView = (ImageView) getLayoutInflater().inflate(R.layout.item_grid_image, parent, false);
Log.v("OWL","TEST5");
} else {
imageView = (ImageView) convertView;
Log.v("OWL","TEST6");
}

imageLoader.displayImage(imageUrls[position], imageView, options);
Log.v("OWL","TEST7");
return imageView;
}
}


I cannot see TEST6, TEST7 on the LOGCAT

I attached log blow. please help me or let't me know how to use that library.

Answer

Did you resolve this problem? You need to initialize the imageLoader with the example code on the UniversalImageLoader:

File cacheDir = StorageUtils.getCacheDirectory(context);
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
        .memoryCacheExtraOptions(480, 800) // default = device screen dimensions
        .discCacheExtraOptions(480, 800, CompressFormat.JPEG, 75)
        .taskExecutor(AsyncTask.THREAD_POOL_EXECUTOR)
        .taskExecutorForCachedImages(AsyncTask.THREAD_POOL_EXECUTOR)
        .threadPoolSize(3) // default
        .threadPriority(Thread.NORM_PRIORITY - 1) // default
        .tasksProcessingOrder(QueueProcessingType.FIFO) // default
        .denyCacheImageMultipleSizesInMemory()
        .memoryCache(new UsingFreqLimitedMemoryCache(2 * 1024 * 1024)) // default
        .memoryCacheSize(2 * 1024 * 1024)
        .discCache(new UnlimitedDiscCache(cacheDir)) // default
        .discCacheSize(50 * 1024 * 1024)
        .discCacheFileCount(100)
        .discCacheFileNameGenerator(new HashCodeFileNameGenerator()) // default
        .imageDownloader(new BaseImageDownloader(context)) // default
        .defaultDisplayImageOptions(DisplayImageOptions.createSimple()) // default
        .enableLogging()
        .build();
