I am an experienced Android developer with strong expertise in Java and system-level optimizations. I will implement a persistent foreground service to ensure the app is always active. The service will display a minimal notification to comply with Android background limits. I will use wake locks to keep CPU active when necessary for data transmission. Battery optimization will be bypassed using REQUEST_IGNORE_BATTERY_OPTIMIZATIONS. I will configure the app for Doze mode exemptions to avoid suspension during idle. The app will be designed to restart automatically if killed by the system or user. I will implement a JobScheduler/WorkManager fallback for redundancy. Special handling will ensure stability on Android 10 and above devices. Testing will be performed in real car scenarios, including BYD sentry mode. I have prior experience integrating apps with vehicle hardware and sensors. My approach ensures 100% uptime for reliable data transfer to your database.

Hello, Nice to meet you! I’m very interested in helping optimize your Android app for BYD vehicles to ensure it runs continuously without interruption. I have extensive experience in Android development with Java, focusing on background services, battery optimization handling, and foreground service implementation. In previous projects, I’ve successfully kept apps running reliably even under strict background execution limits introduced in Android 10+, using techniques like partial wake locks, foreground services with persistent notifications, and Doze mode workarounds. I’m familiar with tuning apps to avoid being killed by system optimizations, and I can ensure your app continues sending data to your database even if removed from the background or when the vehicle is in sentry mode. My approach includes auditing the current codebase, implementing persistent foreground services, integrating proper broadcast receivers for system events, and testing across devices to handle all edge cases. Could you confirm whether you already have any partial foreground service logic in place, or should I build it from scratch? Also, do you require integration with specific BYD hardware APIs beyond standard Android connectivity? I’d love to discuss how I can help bring your project to life. Warm Regards, Bounkyo
