Do you want something easy to use? With take care of caching files, deleting the cache, release when the memory is at border line?

Try LazyList, check it out:

As it is explained, you only need to create the Singleton in your Application class or any other Activity or Fragment:

//To use the default external folder, this folder will be deleted when the app no longe exists.
ImageLoader.getInstance().init(getApplicationContext());
//Or to use another folder, use...
//ImageLoader.getInstance().init(getApplicationContext(), "MyExternalFolder");

Then in your view that has the ImageView to display de Image you need to implement ImageProcessingCallback interface:

public class MyItemView extends LinearLayout implements ImageProcessingCallback {
...
//Do what you need in methods onImagePreProcessing() and onImageProcessing(Bitmap     bitmap)
...
ImageLoader.getInstance().displayImage(data[position], myView);

Finally you need to add this permission in your androidManifest.xml

And that's it. Then you have methods to clear the cache for ram cache or disk cache or both.
