How to get cached bitmap from url?

[sjudd]

The only way to guarantee that you will get a bitmap back is to use the original Glide.load call you used to download and display the bitmap originally.

sjudd, could you elaborate - I've got a bitmap loaded in one activity like:

Glide.load("foo.png").into(myImageView);

then I kill all my network connections, start a new activity, make a call with the same url:

Glide.load("foo.png").into(anotherImageView);

but this one fails to load anything. I was expecting the bitmap from the original request to be in the mem cache, or at least in a disk cache.

Using the 2.x release.

Do both image views have the same dimensions? The dimensions returned by the Target (in this case ImageViewTarget: https://github.com/bumptech/glide/blob/master/library/src/com/bumptech/glide/presenter/target/ImageViewTarget.java) are included in the cache key.

If they do, as long as all the options specified in the Glide.load call are the same in both cases and the disk cache isn't full, what you describe should work.

Ok thanks got it, I used a simple target as shown in this ticket:

#55

to make sure I get a cache hit. I supply the exact width and height of the imageview from the first activity, then use the cache hit as needed with the second activity.

The library has been working great!

Glad it's been working, thanks for the question!
