How to get File object from response body in OkHttp?

Question

I download videos using OkHttp in my application. To play the video, I need to download it completely and then play it using a File object.

I couldn't find a good way to get the File object from the underlying DiskLruCache in OkHttp. Right now I use the InputStream of response body to pipe the response in another DiskLruCache in order to receive a File object and play it.

I think it's not a good idea to have multiple DiskLruCaches. Is there any good way to get a File object from the cached response in OkHttp?

Answer 1

You can't, and you shouldn't want to anyway. The problem is that OkHttp's disk cache may evict files as you're using them. It doesn't have any mechanism to pin a file for a purpose other than its own.

Instead you need to manage the lifecycle of these downloads manually: how many to store, when to delete them, etc.
