I need a small, production-ready Flutter application that triggers a background job every 15 minutes—regardless of whether the user has swiped the app out of Recents or the device has gone to sleep. In my final build that job will change the wallpaper, but for this proof-of-concept just increment a counter stored in SharedPreferences and show the current value as plain text on the main screen when the app opens. Core requirements • The task must fire reliably on all modern Android devices (Samsung, Vivo, Pixel, Xiaomi, etc.) without relying on the user to tweak system settings manually. • On first launch the app should request the following permissions through standard in-app dialogs: – Disable battery optimization – Run in the background – Access device storage • If the user denies a permission, show a friendly in-app explanation and the option to try again. • The background trigger must survive process death, device reboots, and OEM power-saving quirks. WorkManager, AlarmManager plus a foreground service, or another robust approach is fine as long as it complies with recent Android API policies. But it should not show the active notification of app running in background. • iOS support is not required. Deliverables 1. Complete Flutter project with code. 2. Debug APK that I can sideload and observe the counter climbing every 15 minutes.

Hi! Quick read — what you're describing is a classic AlarmManager + silent foreground-service combo, with WorkManager as a fallback for OEMs that throttle hard. I've shipped this exact pattern on Vivo/Xiaomi where battery optimization usually breaks it. I'll prompt for battery-optimization-disable, background run, and storage perms cleanly on first launch, write the counter to SharedPreferences each tick, and hand over the full Flutter project + debug APK so you can sideload and watch the counter climb every 15 minutes — no visible notification. Quick question: do you want the counter to also persist across app reinstalls, or only reboots? — Rohan, APIE Tech

Hello and warm greetings! Your Flutter background task application requirement is well understood, and I can help you build a reliable Android-only solution designed to work consistently across modern devices including Samsung, Xiaomi, Vivo, OnePlus, and Pixel. The app will be developed using Flutter with a robust background execution architecture using WorkManager, AlarmManager, and native Android service handling to improve reliability against sleep mode, process termination, reboots, and OEM battery restrictions. For this proof-of-concept: • A background task will trigger every 15 minutes. • The task will increment a counter stored in SharedPreferences. • The updated counter value will display on the home screen when the app opens. • The process will continue even after app removal from Recents or device restart. I will also implement: • Runtime permission requests for battery optimization, background activity, and storage access. • User-friendly retry dialogs if permissions are denied. • Production-ready clean code architecture. • Proper Android API-compliant service configuration. • Testing across multiple Android OEM environments for stability. I also have a few recommendations to maximize background reliability while staying compliant with modern Android policies. Let’s connect in chat and discuss the implementation details further. Thank you!

Hi, I can build this Flutter Android proof-of-concept for you, including: - Reliable background execution every ~15 minutes - Persistence after app removal from recents, device sleep, and reboot - SharedPreferences counter update logic - Permission handling with retry flows - OEM-aware Android background handling (Samsung, Xiaomi, Vivo, etc.) - Debug APK for testing One important note: due to modern Android restrictions, exact 15-minute execution on all devices without any system limitations cannot be fully guaranteed without a foreground service notification. However, I can implement the most stable and production-compliant approach possible using WorkManager + Android background optimization handling. Best regards

☘️ Your app’s background job should be more loyal than a morning coffee addiction — even Samsung’s battery killer shouldn’t scare it away ?. I understand you need a production-ready Flutter Android app where a reliable 15-minute background task survives reboots, process kills, sleep states, and OEM restrictions while quietly updating SharedPreferences without persistent foreground notifications. I can build this using Flutter + native Android services (WorkManager/AlarmManager hybrid with boot receivers and optimized scheduling), including permission handling for battery optimization, background execution, and storage access with clean retry flows and user-friendly explanations. The app will include a lightweight UI showing the live counter value, structured code, proper lifecycle/error handling, and testing across major Android vendors like Xiaomi, Vivo, Samsung, and Pixel for maximum reliability. I’ll also provide clear documentation, build instructions, and recommendations for long-term stability under modern Android API policies so the app can run calmly and unattended. ☘️
