LocoQuest - Android Geolocation Scavenger Hunt Application

LocoQuest is an Android app I built that uses geolocation to create an interactive scavenger hunt. I built it with Kotlin and the Android SDK. The app guides users to real-world benchmarks and landmarks, turning exploration into a game.

Repository: LocoQuest on GitHub

Project Overview

LocoQuest turns traditional scavenger hunts into a digital, location-based experience. Users get quests that guide them to specific locations where they can find benchmarks, landmarks, or points of interest. The app uses GPS to track location and provide navigation.

The Problem

Traditional scavenger hunts and location-based activities face several limitations:

  • Lack of real-time location tracking
  • Difficulty verifying user presence at target locations
  • Limited interactivity and feedback
  • No persistent record of completed quests
  • Challenges in organizing and managing multiple quests

LocoQuest solves these problems with a digital platform that combines GPS navigation, location verification, and game-like elements.

  • UI/UX Design: Created intuitive user interface for quest navigation
  • Database Design: Implemented local storage for quest data

Technical Implementation

  • Location Services: Configured and managed GPS location tracking
  • Permission Handling: Implemented runtime permissions for location access
  • Background Services: Created services for location tracking
  • Map Integration: Integrated mapping functionality for navigation

Code Quality

  • Kotlin Best Practices: Utilized modern Kotlin features and idioms

  • Performance Optimization: Optimized battery usage and location accuracy

Technical Challenges

Location Accuracy

Challenge: Ensuring accurate location detection, especially in areas with poor GPS signal.

Solution: Implemented hybrid location services using both GPS and network-based location, with accuracy thresholds and fallback mechanisms.

Battery Optimization

Challenge: Location tracking can significantly drain device battery.

Solution: Implemented efficient location update strategies, using appropriate update intervals and location request priorities based on app state.

Permission Management

Challenge: Handling Android runtime permissions for location access, which requires user approval.

Solution: Created a comprehensive permission request flow that explains the need for location access and handles permission denial gracefully.

Offline Functionality

Challenge: Providing core functionality when internet connectivity is limited.

Solution: Implemented local database storage for quest data and cached location information, allowing basic functionality without constant connectivity.

Conclusion

LocoQuest shows how I applied mobile development skills to build a location-based app. The project uses Kotlin, Android SDK, and geolocation technologies to solve real challenges in mobile development.

Building this app taught me about native Android development, location services, and mobile UI design. It also showed me how important battery optimization, user privacy, and performance are in mobile apps.

The skills I learned here apply directly to professional mobile development work and show I can build location-aware apps that are useful to users.
