Google announced app archiving back in March, a feature that will let users "reclaim ~60% of app storage temporarily by removing parts of the app rather than uninstalling it completely." They didn't confirm at the time which platforms would support app archiving, but I've spotted evidence that Android TV/Google TV will be supported.
In the commit history for bundletool, the tool that generates .apks from Android App Bundles, the upcoming 1.10.1 release hints at support for generating archived APKs that work on Android TV/Google TV.
If you're curious about how app archiving works under the hood, I wrote a blog post that goes into the archived APK format based on an analysis of bundletool's source code.
What a pile of bullshit this is.
The only reason they have to work on archiving apps is because they keep producing devices that have such tiny storage that you can't even install apps.
If they just put a reasonable amount of storage on devices this gross development wouldn't have to happen. Nobody needs archived apps. They just need storage.
