Your call tracking feature will fail compliance audits if you're storing call recordings without explicit user consent and encryption at rest. Most CRM apps I've worked on underestimate the legal risk here - especially if you're handling financial data. Before I map out the architecture, I need clarity on two things: What's your current API authentication method? If you're using basic auth or session tokens without refresh logic, the call sync will break every time the token expires and users will lose data. Are you planning to support Android 13+ scoped storage? The gallery upload feature you mentioned won't work on newer devices without migrating from legacy file access patterns. Here's the technical approach: - KOTLIN + COROUTINES: Refactor call tracking to use background workers with proper lifecycle management so recordings don't corrupt when the app goes to background during a call. - ANDROID TELEPHONY API + PERMISSIONS: Implement runtime permission flows for READ_CALL_LOG, WRITE_CONTACTS, and RECORD_AUDIO with fallback UI when users deny access - most developers skip this and the app just crashes. - RETROFIT + ROOM DATABASE: Build a two-way sync engine that queues API calls locally when offline and reconciles conflicts when connectivity returns - prevents duplicate contacts and missing call logs. - MEDIASTORE API: Use scoped storage APIs for gallery access instead of deprecated WRITE_EXTERNAL_STORAGE to ensure Android 14 compatibility and avoid app rejection during Play Store review. - PHP BACKEND INTEGRATION: Add idempotency keys to your POST endpoints so if a call log sync retries due to network failure, you don't create duplicate records in the CRM. I've enhanced 4 existing financial apps where the original developers left undocumented code and hardcoded API keys. I don't take on projects where I can't review the current codebase first - let's schedule a 20-minute call to walk through your existing architecture and identify what'll break under load.
