Fixes #1241

Testing and Review Notes

~I wasn't able to test these changes but I wrote some tests or fixed the ones that mattered.~ I did some testing but a round of QA for this with varying network connectivity would be great.

To Do

• add “WIP” to the PR title if pushing up but not complete nor ready for review
• [x] double check the original issue to confirm it is fully satisfied
• [x] add testing notes and screenshots in PR description to help guide reviewers
• [x] add unit tests
  • optional: consider adding instrumentation (integration/UI) tests
• consider running this branch in a debug simulator and check for memory leak notifications or any warnings
• [x] request the "UX" team perform a design review (if/when applicable)
• [x] make sure CI builds are passing (e.g.: fix lint and other errors)
• [x] check on the accessibility of any added UI

I'm confused why this replaced #1242. The bulk of my review is there.

I believe there was some CI issues with a PR not running all the things unless it was from a branch part of the main project, so Stefan recommended a new PR that wasn't based on my fork.

There are 15 files out of 37 where you're changing to use requireView() and requireContext() and at least one file fixing semantically valid code of dubious quality. At this stage of the release cycle, I'd encourage those changes— mechanical as they are— to be done in a separate PR.

I separated the mechanical parts in the first commit and the logic part in the second (connectivity API changes).

fixing semantically valid code of dubious quality

It was typing fatigue really, but does not change the behaviour.

Merging the review comments from the old PR here:

Should this be at 28? or at 24? or 29? Either a comment in the code or here.

This would usually match the target version implicitly, but Robolectric does not currently target 29 - we had to do this in AC as well.

I'm not sure what to do about other comments, they seem more informational to me.
