I need an experienced Android engineer to build a private-use app that quietly gathers my day-to-day data—emails, SMS, WhatsApp messages, call logs and recordings, even short microphone snippets captured with the proper foreground service—then runs it through an on-device (or secure cloud) NLP pipeline. The AI should recognise appointments, personal reminders and work-related to-dos, distil them into plain-language “action points”, and surface them back to me in three simultaneous ways: • a live, scroll-able home-screen widget that refreshes itself as new tasks are detected • a dedicated reminder list inside the app with the same content • push notifications for anything time-sensitive or high priority Interaction must be two-way: I can tick items as complete, or the app can periodically ask whether tasks are done so it stays in sync. All state changes should reflect instantly across the widget, list and notification queue. Key considerations • Full Android permissions workflow for SMS, call logs, microphone, notification access and accessibility API where needed • Continuous background collection without draining battery (WorkManager / JobScheduler best practices) • Local encryption of raw data and inference results; nothing readable should leave the device unless explicitly routed through a secure API endpoint I configure • Modular AI layer: you may integrate TensorFlow Lite, OpenAI APIs or a comparable model, provided it can run entity extraction and intent detection reliably • Minimum target SDK 31; written in Kotlin with clean architecture so I can extend it later Deliverables 1. Signed APK plus source code in a private Git repo 2. Brief setup guide outlining required API keys and permission steps 3. README describing the AI pipeline and how to retrain or swap models Acceptance will be based on: – Accurate extraction of at least 80 % of actionable items from a supplied test data set – Real-time widget refresh under five seconds after new content arrives – Battery impact under 2 % per hour during continuous collection test window Let me know which NLP stack you prefer and any prior work you can reference that touches similar permission-heavy Android features.

The battery constraint is what makes this genuinely hard. Continuous background collection across SMS, call logs, microphone, and accessibility API simultaneously on Android 12+ without exceeding 2% per hour requires very deliberate WorkManager scheduling, intelligent batching of NLP inference calls, and knowing exactly which operations to run on-device versus offload to a secure endpoint. Most developers will get the permissions working and the data collection running, then you test battery impact and it's sitting at 8% per hour because someone ran TensorFlow Lite inference on every incoming SMS individually instead of batching. The widget refresh under 5 seconds also conflicts with Android's background process restrictions. Achieving that reliably requires a foreground service architecture, not a periodic WorkManager task, with proper notification to satisfy Android's requirements without annoying the user. I build production Android apps in Kotlin with background service handling, WorkManager best practices, and permission-heavy features that actually survive real device usage. Live apps on Play Store. Signed APK, source code, AI pipeline using TensorFlow Lite for on-device inference with OpenAI API fallback for complex extraction, setup guide, README documenting the model layer. What's your primary data source, is email, SMS, or WhatsApp generating the most actionable items for you currently? That determines where to focus the NLP accuracy first.
