The previous rewrite left the entire old class body (companion object, mediaSessionCallback, lifecycle overrides, launchMainActivity helpers) dangling outside the new class closing brace — a Kotlin syntax error. Gradle was using the last successfully compiled APK, so Android Auto received a broken service and showed 'doesn't seem to be working'. Remove lines 362-581 (old code), leaving only the new clean class. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
