This is my code :

Glide.with(this)
.load("https://farm8.staticflickr.com/7489/15428306664_6903c2f82d_o.gif")
.into(img);

You can see heap dump file at here

See this stacktrace , I understand my application has leak memory when I trying load a large GIF image,but i don't find the reason:(.Please help me resolve it.Thanks you.

A 3840x2880 example is http://media4.giphy.com/media/ToMjGpquWkOQon5nAvS/giphy.gif.

Probably the most reasonable thing is to catch the exception, allow the load to fail, and encourage users to not try to load gigantic gifs, but we may also be able to find some reasonable way of downsampling GIFs the same way we do Bitmaps.
