Project description:
"I have a fully-functional native Android app and complete REST API documentation ready to share. I now need the endpoints for user authentication, data fetching, and data submission wired seamlessly into the existing codebase.

The job covers:
• Implementing all documented endpoints (login, refresh, GET, POST, etc.) using a robust client such as Retrofit/OkHttp or an equivalent approach that fits cleanly with our current architecture.
• Handling token storage, refresh logic, and error cases so the app remains stable offline or on flaky connections.
• Parsing and posting JSON exactly as outlined in the docs, with clear model classes and concise helpers.
• Returning the updated, well-commented source so I can trace every change in Android Studio and continue future work without guesswork.

Acceptance will be based on these criteria:
1. Successful login/logout flow against the live server.
2. Data lists render from the GET endpoint within 2 seconds on a standard 4G connection.
3. New records post and persist correctly, confirmed by a subsequent fetch.
4. All new code builds cleanly with no lint or unit-test failures.

If you have solid experience in native Android networking and can turn this around quickly, I’ll send over the repository link and full API spec as soon as we agree to start." (client-provided description)
