Cross-Platform Video Camera App

I need a straightforward camera application that records video with clear, synchronized audio on both Android. .

Deliver fastest and most reliably.
• Reliable video capture up to each platform’s standard maximum resolution, with continuous audio.
• A minimal interface: record/stop button, runtime counter, and a small gallery link to review the clip.
• Basic settings screen for resolution and microphone source selection

Deliverables
- Production-ready APK
- Source code pushed to a private repo I provide
- Short README covering dependencies and build steps

Acceptance criteria
1. Android releases.
2. App launches and starts a new recording in under two seconds on mid-range devices.
3. No crashes or frame drops during a continuous five-minute recording test.
