Android: Cache image by android class or manual way? -


when develop android app download , caching image internet, see many app use memorylrucache or disklrucache cache image after download. want know why use them, why don't use way like: download image, save image sd card , after image sd card show it( manual way). i'm newbie in android dev. please me understand it? many many times.

well downloading list of images url consume time , fill user memory also....so better dynamically load images url , make cache , preview images cache..

i hope did got point....check example of lazy loading of image
