Universal image downloader UIL nostra memory error

I use UIL to load deleted images and fill fragments in the FragmentStatePagerAdapter. I read readme and common errors, but I can not solve this error.

Here is the configuration:

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext()) .threadPoolSize(1) .build(); ImageLoader.getInstance().init(config);

Here I show 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 this is where I will 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, this is what I get:

I do not know how to solve it. Uploaded images are resized. They can range from 500 KB to 1.5 MB.

SOLVE:

This is not a UIL problem. The problem was with the page adapter. The bitmaps in the Fragments were not properly handled by the GC, and there was some indirect reference preserving them. The release of bitmaps clearly solved the problem.

EDIT:

This was not a valid UIL problem. I worked with the SupportFragment library, and this may not be configured correctly. A trick for me was manually released every bitmap that was not on the screen, but the problem should be treated differently. This application uses a very large number of WebViews, which, in my opinion, are evil due to the fact that their memory consumption is simply stupid! Adding a UIL with hi-res images makes my application go to OOM due to a combination of these factors.

This is a slightly empirical solution, but it really works.

From the above link

If you often get OutOfMemoryError in your application using the Universal Image Loader, then try the following (all or more):

  • Reduce the thread pool size in the configuration (.threadPoolSize (...)). Recommended 1 to 5.

  • Use .bitmapConfig(Bitmap.Config.RGB_565) in the display options. Raster images in RGB_565 consume 2 times less memory than in ARGB_8888 .

  • Use .memoryCache(new WeakMemoryCache()) in the configuration, or disable memory caching in the display options at all (do not call .cacheInMemory ()).

  • Use .imageScaleType(ImageScaleType.IN_SAMPLE_INT) in the display options. Or try .imageScaleType(ImageScaleType.EXACTLY) .

  • Avoid using RoundedBitmapDisplayer. It creates a new Bitmap object with the ARGB_8888 configuration for display during runtime.

Example: modify c.ode in the link below, following the points above to avoid OOM

I have the following configuration with disk cache . I have never encountered an OOM problem.

 ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder( YourActivity.this).threadPoolSize(5) .threadPriority(Thread.MIN_PRIORITY + 3) .denyCacheImageMultipleSizesInMemory() // .memoryCache(new UsingFreqLimitedMemoryCache(2000000)) // You // can pass your own memory cache implementation .memoryCacheSize(1048576 * 10) // 1MB=1048576 *declare 20 or more size if images are more than // 200 .discCache(new UnlimitedDiscCache(cacheDir)) // You can pass your own disc cache implementation // .defaultDisplayImageOptions(DisplayImageOptions.createSimple()) .build();

To create a cache dir ,

 File cacheDir = new File(this.getCacheDir(), "imgcachedir"); if (!cacheDir.exists()) cacheDir.mkdir();
