How to pause/resume requests?

[rogererill]

Hi, I'm in the process of migrating my app from Picasso to Coil, and I wondered if there was an equivalence to Picasso's method to .pauseTag(tag) and .resumeTag(tag).

I have this piece of code:

override fun onScrollStateChanged(recyclerView: RecyclerView, newState: Int) {
    super.onScrollStateChanged(recyclerView, newState)
    if (newState == RecyclerView.SCROLL_STATE_DRAGGING) {
        picasso.pauseTag(MY_TAG)
    } else {
        picasso.resumeTag(MY_TAG)
    }
}

I have read this but I wonder if there's a better way nowadays. I'm not really sure how could I access the Interceptor to set it as "paused" when creating the request.

Thanks

@rogererill That's still the recommended way to implement pausing + resuming. If you use the singleton ImageLoader then you could make the PauseInterceptor and object else I'd probably inject it with dependency injection.

It might also be useful for your use case, but you can attach metadata to a request using ImageRequest.Builder.setParameter. Those can be accessed inside the Interceptor.

Hi @colinrtwhite thanks for your response! A slightly modified implementation of the proposed solution did successfully pause the requests, but then I had to add some code that stored the incoming requests that were coming while the app was in this "paused" state so I could resume then later.

It feels a bit hacky but I guess I managed to find a good workaraound. Thanks again!
