Challenge 3: Sorting Chapter 7's Own Tools by Origin — Solution Walkthrough

Inherited from IntelliJ:

  - The Rename refactoring
  - Extract Method

Both are general-purpose refactoring capabilities built into the
shared IntelliJ Platform, working identically in PyCharm, WebStorm, or
any other IDE built on the same base — not something Google added
specifically for Android.

Android-specific:

  - A lint warning about a missing content description
  - A lint warning about a hardcoded string that should be in
    strings.xml

Both are specific rules within Android Lint's own rule set — a missing
content description is an Android accessibility concept tied to
Android's own View system, and strings.xml localization is an
Android-specific resource convention. Neither check would exist in a
non-Android JetBrains IDE, since neither concept applies outside
Android development.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise directly applies Chapter 1's own inherited-vs-Android-
specific framework, revisited in this chapter's own tip box, to a
fresh set of four concrete examples — correctly sorting each one by
whether it comes from the shared IntelliJ platform or Android's own
specific tooling.
