Hi, I can build your Android anti-theft alarm app in Kotlin with reliable motion detection using the accelerometer and charger-disconnect monitoring. The app will trigger a loud siren that overrides silent mode, include a secure PIN to disarm, and run as a background service so it cannot be easily closed. I’ll design a clean UI with Arm/Disarm controls, and add optional vibration and flash alerts for stronger deterrence. If desired, I can also include sensitivity settings, auto-start after reboot, and email alerts when the alarm triggers. You’ll receive the complete Android Studio project, installable APK for testing, and clear documentation explaining setup and usage.

Hello! I can help develop a lightweight Android anti-theft alarm app with reliable motion detection and strong background protection. I have experience building sensor-based Android applications and focus on creating apps that are stable, efficient, and easy to maintain. For this project I would: • Implement motion detection using the accelerometer to trigger the alarm when the phone is moved. • Detect charger unplug events and activate the alarm immediately. • Build a loud siren that plays even in silent mode using appropriate audio channels. • Add a secure PIN lock screen required to stop the alarm. • Run the system through a persistent background service to prevent easy closure. • Design a simple interface with Arm / Disarm controls for quick activation. • Include optional vibration and camera flash alerts for stronger warning signals. Optional features can include: • Adjustable motion sensitivity • Email alerts when the alarm triggers • Auto-start after device reboot Deliverables will include: • Complete Android Studio project (Kotlin) • Testable APK • Clear documentation and commented code The app will support Android 10+ and follow best practices for reliability and performance.

Hi there, I will build your Android anti-theft alarm app in Kotlin with motion detection via the accelerometer, charger-disconnect triggering, a loud siren that overrides silent mode, and PIN-based deactivation. The app will include a simple Arm/Disarm UI, background service persistence, and optional vibration plus flash alerts. For the background service, I will use a foreground service with a persistent notification rather than a plain background service. This approach prevents Android 10+ from killing the process and keeps the alarm reliable without excessive battery drain. I will also handle the BOOT_COMPLETED broadcast so the app restarts after reboot automatically. Questions: 1) For sensitivity adjustment, should this be a simple slider (low/medium/high) or a precise numeric threshold the user controls? 2) Do you have a preferred email delivery method for alerts, such as SMTP directly from the device or a lightweight backend/Firebase function? Looking forward to discussing further. Thanks and best regards, Kamran
