NetworkStatsManagerandTrafficStatsfor real-time speed calculation and per-app usage tracking. - Traffic Management: Implementation of
VpnServicefor on-device traffic interception, enabling precise per-UID internet restriction. - Background Processing: Robust
ForegroundServiceensuring 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
CanvasAPI 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.
- Grant Permissions: Follow the setup wizard to enable Usage Access and Notifications.
