I am using UIL to load remote images and fill up Fragments in FragmentStatePagerAdapter. I have read readme and usual errors but I can't solve out this bug.
Here is the config:
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext())
.threadPoolSize(1)
.build();
ImageLoader.getInstance().init(config);
Here is where i display my images:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
ImageLoader imgLoader = ImageLoader.getInstance();
DisplayImageOptions options = new DisplayImageOptions.Builder()
.showStubImage(R.drawable.loading)
.cacheOnDisc()
.resetViewBeforeLoading()
.bitmapConfig(Bitmap.Config.RGB_565)
.imageScaleType(ImageScaleType.IN_SAMPLE_INT)
.build();
imgLoader.displayImage(this.contentImage, this.imgView, options);
return layout;
}
And here is where I destroy my fragments in the adapter:
public void destroyItem(ViewGroup container, int position, Object object) {
if (position >= getCount()) {
container.removeAllViews();
FragmentManager manager = ((Fragment) object).getFragmentManager();
FragmentTransaction trans = manager.beginTransaction();
trans.remove((Fragment) object);
trans.commit();
}
}
and finally here is the exception I get:

I don't have any idea in how to solve it. Loaded images are variable in size. They may vary from 500KB to 1.5MB.
SOLVED:
It wasnt't a UIL problem. The problem was with the page adapter. The bitmaps in the Fragments weren't handled properly by the GC and there was some indirect reference retaining them. Freeing the bitmaps explicitely solved the problem.
EDIT:
It wasn't a proper UIL problem. I was working with SupportFragment library, and this may be not properly tweaked. The trick for me was manually release every bitmap that was not on screen, but the problem should be looked at in a different way. This application uses a very large amount of WebViews, that in my opinion are evil due to fact that their memory consumption is simply silly! Adding UIL with hi-res images makes my app going OOM due to the combination of these factors.
It's a bit empirical solution, but it really works.
