Geo GPS Camera
Production Android application with verified Play Store distribution. Secure location-tagged image acquisition with server-side GPS coordinate validation.
The Challenge
Trustworthy
location provenance.
Field operations across industries — construction verification, insurance claims, agricultural surveys — require photographic evidence with verifiable location metadata. Standard camera applications embed device GPS coordinates, which are trivially spoofable. The challenge was to engineer an application that captures images with cryptographically trustworthy location provenance, resistant to GPS spoofing and metadata tampering.
The Architecture
Validated
capture pipeline.
Jetpack Compose UI
Modern declarative UI built entirely in Jetpack Compose. Real-time camera preview with location metadata overlay, address resolution, and coordinate display rendered directly on the viewfinder.
CameraX Integration
Camera pipeline implemented via CameraX for consistent behavior across Android device fragmentation. High-resolution image capture with metadata embedding at the hardware level.
GPS Spoofing Detection
Server-side coordinate validation comparing device GPS, network-based location, and cell tower triangulation. Anomaly detection identifies spoofed coordinates and flags compromised captures.
Play Store Distribution
Full production release pipeline: ProGuard optimization, app signing, Play Console compliance, staged rollout, and crash monitoring via Firebase Crashlytics.
The Outcome
Production
deployment.
The application is live on the Google Play Store with verified distribution. GPS spoofing detection ensures location data integrity for field operations requiring verifiable photographic evidence. The Jetpack Compose architecture enables rapid feature iteration while CameraX provides consistent capture quality across the fragmented Android device landscape.
