Component used: Recommendation Channel
Version used: 'androidx.recommendation:recommendation:1.0.0' / 'androidx.tvprovider:tvprovider:1.0.0'
Devices/Android versions reproduced on: Android 9
My app supports Recommendation Channels for the Home screen. I'm in a relatively unique position, because the app shows Live stream cards inside the Recommendation channel.
The problem is, these live streams has a static image link, which means the image's link doesn't changes, but the content of the image does.
(i'm hoping this is really a 24/7 stream, so you don't get 404 when you check this post)
The content of the image gets updated every ~5 minutes. Inside the app i use Glide to download these images, and i use Glide's Cache Invalidate feature. (https://bumptech.github.io/glide/doc/caching.html#cache-invalidation) Basically i use a handler that runs every 5 minutes, and updates a global string with the current DateTime, this is my "signature".
This way i can force Glide to re-download the the preview thumbnails every 5 minutes.
So back to my issue, with Recommendation channel these images get downloaded once, and never will be updated again. Which means the Channel cards show months old previews. With a movie poster this is not an issue, but with live streams is.
So i would like to request the following feature:
When i'm creating the Channels cards, with a new method i could force an image invalidation:
PreviewProgram.Builder builder = new PreviewProgram.Builder();
builder.setInvalidatePosterArtUri(true)
(i use PosterArtUri to set the thumbnail)
If this is not set, normal caching can occur, but when it's necessary we can force an update.
