Fixing an Expo SDK 54 Android Build Broken by Mixed SDK 55 Packages

EDITOR BRIEF

An Android build failed in an Expo SDK 54 app because several Expo packages had been upgraded to versions meant for SDK 55. TypeScript and the dev server did not reveal the problem; it showed up later during EAS Build’s native step. The author used Expo CLI checks to find the mismatch and then updated package versions in package.json.

INSIGHTS

This shows that package versions can look fine in code but still break native builds. If you use Expo, run `npx expo install --check` before building, and learn how SDK compatibility differs from simple major-version matching.
