Android App API Modification

@Microlent

Hello! I understand you need an experienced Android developer to review and modify your existing app’s API layer while ensuring current functionality remains stable. Here’s how I’d approach it: • Review current API integration (Retrofit/Volley/GraphQL client setup) • Analyze API documentation and identify required endpoint changes • Refactor request/response models to match updated schemas • Implement new endpoints or modify existing ones • Improve error handling, token refresh logic, and retry mechanisms • Validate performance and edge cases through structured testing If needed, I can also: • Optimize network calls and caching • Clean up architecture (MVVM/MVI) for maintainability • Ensure backward compatibility during rollout Deliverables: • Updated Android app with revised API integration • Clean, well-documented code • Verified API communication with proper error handling • Guidance for future API updates I’ve worked extensively with RESTful and GraphQL APIs in Android apps, including version migrations and production hotfixes. Let’s open the chat and review your current API documentation and required changes. Best regards, Jasmin

@royalwebraisers

Hi, As per my understanding: Modify APIs in existing Android app—update/revise REST/GraphQL/SOAP endpoints per docs, ensure seamless integration w/current codebase. Implementation approach: - Reverse-engineer Retrofit/OkHttp calls, update per new specs. - Test w/Postman mocks, handle auth/errors, UI sync. - Git commits w/docs for changes. I will share my portfolio on your first message. Queries: Repo access? API docs/link? Specific endpoints? Quick fix ahead!
