Remove image from cache / clear cache issue

[BenjaminZaiser]

Dear development team,

I'm using Glide to display product images in my app, e.g. on product detail page:

Glide.with( context )
         .load( url )
         .thumbnail( Glide.with( context )
            .load( placeholderResId )
            .apply( new RequestOptions()
               .centerCrop() ) )
         .into( productImageView );

The caching mechanism of this library is really great to reduce the used bandwidth of the user, but now I have some problem where I need your help:

Given product detail page is displayed along with a product image.
When user deletes product image
and reopens product detail page
Then product image should not be visible anymore (placeholder should be shown).

Problem:
Currently the product image will be loaded from the cache and is displayed to the user which is not expected.

I would like to have the feature to delete a single image in the cache. But I found out, this is not possible.
I found this #552 and decided to go with the 1st solution, although it has some disadvantages for the user (deletion of product images is very rare).

Calling Glide.get( getApplicationContext() ).clearDiskCache(); is not sufficient, because the image could still be in the memory. So I have to call Glide.get( getApplicationContext() ).clearMemory(); as well. But when I want to open the product detail page again, I get the following error message:

java.lang.IllegalStateException: cache is closed

What do I need to do to "reinitialize" Glide? Or do you have another approach to the problem?
Thanks
Ben

Maybe a duplicate of #2465, let me know if you're able to reproduce in 4.4.0 or higher.

Also you're probably better off using a signature unless you need the actual bytes deleted off of disk. See http://bumptech.github.io/glide/doc/caching.html#cache-invalidation
