hi, I have written 2 connected apps with some image content pulled from the web and must say if you handle your resources right it shouldn't be a problem at all.
Do you use your own Adapter for the GridView or do you use some of the already available ones in the SDK? If you use your own you should keep in mind that when you deal with AdapterViews in general they keep references to Views you create in your adapter and recycle them, so try to reuse the convertView reference you get in the Adapter.getView (int position, View convertView, ViewGroup parent) method. And although memory leaks are difficult to achieve in what sounds like a single activity app the other thing that comes to mind is that you might have memory leaks due to the way you use Drawables. Try using Bitmaps from the BitmapFactory.decodeStream(InputStream) method and maybe read this blog for more info why Drawables could cause memory leaks - http://android-developers.blogspot.com/2009/01/avoiding-memory-leaks.html. cheers, gesh.
