Transaction Map Feature with Real-Time Updates

Overview

The Transaction Map Feature is a key functionality designed to provide users with a geographic visualization of their financial activities. It displays transaction locations on an interactive map, with real-time updates and offline capabilities. This multi-threading feature ensures smooth performance by handling location data synchronization and map updates in parallel, maintaining app responsiveness while processing complex geographical and transaction data.

Key Features

Real-Time Transaction Visualization

• Shows transaction locations with color-coded markers (yellow for income, red for expenses).
• Updates marker positions in real-time as new transactions occur.
• Indicates transaction anomalies with visual alerts.

Multi-Threading Architecture

• Utilizes background threads for data processing and synchronization.
• Updates map markers without blocking the main UI thread.
• Processes location data and transaction updates concurrently.
• Performs periodic checks for new transactions every 30 seconds.

Offline Capabilities

• Stores transaction location data locally for offline access.
• Syncs automatically when connection is restored.
• Provides visual indicators for offline mode and pending synchronization.

Location-Based Insights

• Displays transaction amounts and types at each location.
• Shows transaction history geographically.
• Helps identify spending patterns based on location.

How It Works

Triggering Updates

• The feature automatically monitors for new transactions in the background.
• Updates occur when new transactions are added or when offline data is synced.
• User location is captured at the time of transaction creation.

Multi-Threaded Processing

The feature uses multiple threads to handle different tasks:

• UI Thread: Renders map and handles user interactions.
• Background Thread: Processes transaction data and updates markers.
• Sync Thread: Manages data synchronization with the server.
• Location Thread: Handles location services and coordinate processing.

Network Connectivity Management

• Monitors network state continuously.
• Switches to offline mode automatically when connection is lost.
• Queues updates for synchronization when connection is restored.
• Provides visual feedback about connectivity status.

Data Synchronization

• Automatically syncs local and server data.
• Uses timestamps to track changes and updates.
• Manages conflicts between local and server data.
• Updates UI to reflect synchronization status.

Benefits

• Visual Insights: Users can visualize their spending patterns geographically.
• Performance: Multi-threading ensures smooth map interactions and updates.
• Reliability: Offline support maintains functionality without internet.
• Real-Time Updates: Immediate reflection of new transactions on the map.
• User Experience: Seamless integration of location data with financial information.
