Looking for a way to handle error

[lalith-b]

It could be great if there's a ErrorListener to check and handle errors. I'm in a situation where I could get Javascript/JS files along with images.

If the downsampler couldn't downsample it would be great if I could get a error listener.

The case you mention can definitely occur, you will see something similar if you try to load a url and get a 404 for example.

I'll look in to adding an exception handler. There is one for ImagePresenters if you're using them directly: https://github.com/bumptech/glide/blob/master/library/src/com/bumptech/glide/presenter/ImagePresenter.java#L246

Out of curiosity, what would you want to do in the error listener/exception handler? Try loading the image again?
