smart_battery_android

A lightweight, open-source Android application designed to help users optimize battery health by notifying them when to charge and unplug their device based on ideal battery percentage ranges. The tool monitors battery levels in real-time and provides customizable notifications when it’s time to take action, helping extend battery lifespan. All monitoring and notifications are processed locally on your device, ensuring maximum privacy.

Key Features:

• Real-Time Battery Monitoring: Continuously tracks battery levels. • Configurable Thresholds: Users can set personalized notification triggers (e.g., start charging at 35%, unplug at 75%). • Customizable Notifications: Users can choose between toast notifications or standard status bar alerts. • Secure Local Settings: All preferences are stored securely on the device using Jetpack DataStore. • Efficient Background Operation: Employs a hybrid strategy (WorkManager for periodic checks, and real-time listeners like BroadcastReceiver for intensive monitoring near thresholds) to minimize battery impact while ensuring timely alerts. • Privacy-Focused: All operations are performed locally; no data is sent to external servers. • Open-Source & Customizable: Freely available on GitLab and adaptable to user needs. • Available on F-Droid: Distributed via F-Droid for easy, privacy-respecting access.

Technology Stack:

Language: Kotlin

• UI: Jetpack Compose • Background Processing: Android WorkManager, BroadcastReceivers (and potentially Foreground Services for intensive phases) • Notifications: Android NotificationManager • Data Storage: Jetpack DataStore • Development Tools: Android Studio, GitLab CI/CD

smart_battery_android empowers users with a secure, customizable, and efficient solution for managing their Android device's battery health, all while respecting user privacy.

notification_hub is a lightweight, open-source Android application built in Kotlin that monitors incoming SMS messages from user-selected apps in real time and automatically initiates a voice call to deliver a pre-recorded alert.

Technology Stack:

• Language: Kotlin • Frameworks & APIs: Android SDK and Android Jetpack (WorkManager, Foreground Service) • Telephony Management: Native Android Telephony APIs for SMS detection and voice call management • Data Persistence: Room Database for secure, on-device configuration storage • Development Tools: Built with Android Studio and integrated with CI/CD on GitLab
