Thank you Streets of Boston for your response, This was just a test project. I was using a 4MP image to get at that precisely to determine how much images we can use in a layout.
If an UI uses a lot of drawables that combined uses a lot memory, application will be at some point Out Of Memory errors. We are working on an application which its UI is based mostly on images (drawables) and also download images to present "thumbnails" of items, making your suggestion of "nulling" references of those images really complicated since most of the items that uses images are not retrieved using findViewById method. -f4 On Apr 29, 2:58 pm, Streets Of Boston <[email protected]> wrote: > How big is drawable/domo2048? > Is it 4MPixel.
