Android Universal Image Loader and GridView "Out of memory" on second launch

I have checked all the related posts so far, but did not managed to fix this "Out of memory on a 1843216-byte allocation" error my GridView activity generates.
Basically this activity displays the images from the phone's gallery in a GridView (as a multiple image picker), at first it loads everything just fine, at the second try I get the memory error and the GridView skips loading some of the image thumbnails.
I have disabled the memory caching by: ".cacheInMemory(false)", and using only disk caching with fixed ImageView width and height, but still got the memory error.
Could someone help me out? Thanks!

Try to do this with Picasso library instead of using image loader library. Hope this may helpful for you.

How do i get the position of a URL in an array?

What I'm trying to achieve is to obtain the URL received from Instagram and pass its array position to an onlick listener for each corresponding photo in a grid view.

}
}
FullScreenImageView.java
import android.app.Activity;
public class FullscreenImageView extends Activity {
String imageURL = getIntent().getStringExtra("SelectedImageURL");
}

The workflow of the gridView as you understood is to have an adapter to populate this view.
What I would do is that the getItem(int position) returns the URL which, if I good understood, is contained in your mPhotoList. Something like:
#Override
public Object getItem(int position) {
return mPhotoList.get(position);
}
And use it where you need it like this:
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// Maybe you'll have to cast it to a string, I'm currently writing directly in SO
String url = parent.getAdapter().getItem(position)
Intent myintent=new Intent(MainActivity.this, FullscreenImageView.class).putExtra("SelectedImageURL", url);
startActivity(myintent);
}
});
Hope it helps.

Very old question, but no answer. I'm sure you have found a fix by now, but anyway.
You're changing the songs list object in background, and if Android decides to redraw your list (user scrolls your list), effectively accessing the songs list object, it may have changed and cause this exception to be thrown.
You need to use a temporary songs list and create a new adapter with it to update your list, thus not changing the current adapter list until you set a new adapter from the main UI thread.
