I download and keep a list of photos in my application:

```
List<BitmapDrawable> photos = new ArrayList<BitmapDrawable>();
photos.add(Utils.bitmapToBitmapDrawable(downloadBitmap(s));

public static Bitmap downloadBitmap(String url) {
    // GET input stream from server
    return BitmapFactory.decodeStream(inputStream);
}

```

Trying to deallocate: 

```
if (dldedPics.get(0).getPhotos() != null && !dldedPics.get(0).getPhotos().isEmpty()) {
    for (BitmapDrawable b : dldedPics.get(0).getPhotos()) {
        b.getBitmap().recycle();
    }
}
dldedPics.get(0).setPhotos(null);
Runtime.getRuntime().gc();

```

I can't seem to properly have them deallocated, as I get a OutOfMemoryError (at the decodeStream line) rather quickly, after 10-20 100kb photos.

Stacktrace:
