Android Location Tracking App - Sample Location

A robust, production-ready Android application that demonstrates modern location tracking implementation using Google's Fused Location Provider. The app features clean architecture, comprehensive error handling, and excellent user experience with real-time location updates.

✨ Features

• Smart Permission Management: Automatic runtime permission requests with user-friendly guidance
• GPS Status Monitoring: Real-time GPS availability checking with automatic user prompts
• High-Accuracy Location Tracking: Continuous location updates with configurable intervals
• Comprehensive Error Handling: Graceful handling of all edge cases and failures
• Clean Architecture: Well-organized, maintainable code following Android best practices
• Modern UI/UX: Clean, responsive design with real-time feedback

🚀 Getting Started

Prerequisites

• Android Studio Arctic Fox or later
• Android SDK 24+ (Android 7.0)
• Physical device or emulator with location services

Installation

1. Clone the repository

   git clone https://github.com/pavannamepalli/Sample-Location.git
   cd Sample-Location

2. Open in Android Studio

   • Launch Android Studio
   • Select "Open an existing project"
   • Navigate to the cloned directory

3. Build and Run

   • Connect an Android device or start an emulator
   • Click "Run" or use Ctrl+R (Windows/Linux) or Cmd+R (Mac)
   • Grant location permissions when prompted

4. Usage

   • The app will automatically request location permissions
   • Enable GPS if prompted
   • Watch real-time latitude and longitude updates

📱 How It Works

App Flow

1. Launch → App initializes and requests location permissions
2. Permission Grant → Checks GPS status and starts location tracking
3. Location Updates → Displays real-time coordinates with 6-decimal precision
4. Background Handling → Automatically pauses/resumes based on app state
5. Error Recovery → Provides clear guidance for permission/GPS issues

Key Components

• MainActivity: Core location tracking logic with organized method structure
• Permission Management: Runtime permission handling with user guidance
• Location Services: Google FusedLocationProviderClient integration
• UI Updates: Real-time coordinate display with loading states
• Error Handling: Comprehensive exception handling and user feedback

🛠️ Technical Details

Architecture

• Clean Code Structure: Methods organized by functionality (Lifecycle, Initialization, Permissions, UI)
• Null Safety: Comprehensive null checks throughout the codebase
• Exception Handling: Try-catch blocks for all critical operations
• Resource Management: Proper lifecycle management for battery optimization

🔧 Code Structure

MainActivity.java Organization

├── Constants & Fields
├── Lifecycle Methods (onCreate, onResume, onPause)
├── Initialization Methods (Views, Services, Callbacks)
├── Permission & Location Methods (Permission handling, GPS checks, Location updates)
├── UI Update Methods (Display updates, Toast messages)
└── Callback Methods (Permission results, Activity results)

Key Methods

• initializeViews() - UI component setup
• initializeLocationServices() - Google services initialization
• requestLocationPermissionAndFetchLocation() - Permission flow management
• startLocationUpdates() - Core location tracking
• updateLocationDisplay() - Real-time coordinate display
• stopLocationUpdates() - Battery optimization

🚨 Error Handling

The app includes comprehensive error handling for:

• Permission Denials: User-friendly guidance messages
• GPS Disabled: Automatic settings redirection
• Location Service Failures: Specific error messages
• Null Reference Safety: Prevents crashes from null objects
• Exception Recovery: Graceful handling of unexpected errors

🔋 Performance Optimizations

• Battery Efficient: Stops location updates when app is paused
• Smart Resumption: Only restarts updates when needed
• Configurable Intervals: Balanced accuracy vs. battery usage
• Resource Cleanup: Proper disposal of location services

Development Guidelines

• Follow the existing code organization structure
• Maintain comprehensive error handling
• Add appropriate string resources for all user-facing text
• Test on both physical devices and emulators
• Ensure proper lifecycle management
