Live Coding Session: How do you Build More Privacy Focused Apps?
summary
Live coding converts a messy photomemory app into a privacy-first app: replace custom picker with the Android 13 photo picker (backported to Android 11–12 via Mainline) in under five lines, use the Activity Result API to get URIs and drop storage permission, add a Data Access Audit API listener (API 30) to log permission accesses with stack traces, implement in‑context permission requests plus rationale dialogs (research shows ~54% fewer denials), and switch from fine to approximate location (≈3 km²), which preserves features while tightening privacy.
