There is a library named Picasso which can efficiently load images from a URL  It can also load an image from a file   Examples    Load URL into ImageView without generating a bitmap   Picasso with context     Context         load  http   abc imgur com gxsg png      URL or file         into imageView      An ImageView object to show the loaded image  Load URL into ImageView by generating a bitmap   Picasso with this          load artistImageUrl          into new Target                 Override            public void onBitmapLoaded final Bitmap bitmap  Picasso LoadedFrom from                      Save the bitmap or do something with it here                       Set it in the ImageView                theView setImageBitmap bitmap                            Override            public void onBitmapFailed Drawable errorDrawable                               Override            public void onPrepareLoad Drawable placeHolderDrawable                                There are many more options available in Picasso  Here is the documentation
