FlowBytes is built using modern Android standards with a focus on performance and accuracy:

• Network Sampling: High-frequency traffic analysis using NetworkStatsManager and TrafficStats for real-time speed calculation and per-app usage tracking.
• Traffic Management: Implementation of VpnService for on-device traffic interception, enabling precise per-UID internet restriction.
• Background Processing: Robust ForegroundService ensuring continuous monitoring with minimal battery impact and system-wide visibility.
• Reactive UI: Built entirely with Jetpack Compose following MVVM architecture, utilizing Kotlin Coroutines and StateFlow for seamless data updates.
• Data Persistence: Atomic storage of usage history and configuration using Room Database and Jetpack DataStore.
• Custom Rendering: Dynamic notification icons and status bar indicators rendered via Canvas API for sharp, real-time speed display.

• OS: Android 10 (API level 29) or higher.
• Permissions Required:
  • POST_NOTIFICATIONS: For real-time speed display and urgent alerts.
  • PACKAGE_USAGE_STATS: To accurately calculate per-app network consumption.
  • QUERY_ALL_PACKAGES: To list and monitor all installed applications for usage tracking and blocking.
  • FOREGROUND_SERVICE: To ensure uninterrupted, accurate monitoring.
  • VPN Service: Required for the App Blocking feature to intercept and restrict traffic for apps exceeding limits.
  • Battery Optimization: Recommended to exclude FlowBytes from battery restrictions for reliable background tracking.
