Fixes Android lint warnings found by the lint-android repo tool command, and removes the baseline file.

Also fixes a few warnings that showed up in Android Studio.

Part of flutter/flutter#88011

Pre-launch Checklist

  • I read the Contributor Guide and followed the process outlined there for submitting PRs.

  • I listed at least one issue that this PR fixes in the description above.
  • I updated pubspec.yaml with an appropriate new version according to the pub versioning philosophy, or this PR is exempt from version changes.
  • I updated CHANGELOG.md to add a description of the change, following repository CHANGELOG style.

  • I added new tests to check the change I am making, or this PR is test-exempt.

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.

Apparently they are from 1.4, so not so new. I wasn't familiar with them myself, but the AS wizard suggested it as a possible fix for a potential NPE warning, and it seemed like the right thing in this case since it shouldn't be possible for the variable to be null due to the check above for a variable that's constructed from it at the same time that it's set.
