Aisha is rushing between meetings and needs to call a client, reply to a message, and set a reminder without digging through apps. She opens REA AI, speaks naturally, and the app recognizes her mixed Hindi-English command, confirms the call, and completes the task in seconds.

Later, she uses the same assistant to launch maps and draft a WhatsApp message while walking. Instead of tapping through several screens, she finishes her routine actions hands-free, saves time, and feels more in control of the phone throughout the day. For the business, this creates repeat usage because the product becomes part of her daily workflow rather than a novelty.

Build a production-ready Android voice assistant app called REA AI.

Goal: Users can control common phone actions by voice with natural Hindi, English, and mixed Hindi-English speech. Focus on fast, reliable, hands-free execution for open app, call contact, send message, set reminder/alarm, open settings, launch maps, and review command history.

Tech stack:
Android app in Kotlin with Jetpack Compose, MVVM, Coroutines, Hilt, Room, Jetpack Security Crypto, Firebase Analytics, Crashlytics, and Google Gemini API via AI Studio for intent parsing. Use Android Intents and supported platform APIs for device actions. Use a clean architecture with data, domain, and presentation layers.

Primary screens:
1. Onboarding with language choice, wake method choice, and permission requests
2. Home screen with a large mic button, live transcript, and recent commands
3. Command confirmation screen for sensitive actions like calls and messages
4. Shortcuts screen for favorite contacts, favorite apps, and custom routines
5. Activity/history screen with success, failed, and pending command logs
6. Settings screen for permissions, language, wake phrase, privacy controls, and data deletion

Core flows:
1. First-time setup with permission explanation and a 2-minute time-to-value target
2. Tap-to-talk and optional wake-word trigger
3. Speech-to-text capture, AI intent classification, and confidence scoring
4. Confirmation flow for sensitive actions
5. Execution through Android intents and native APIs
6. History logging with retry, edit, and delete options

Data model:
UserProfile: id, language, preferred wake mode, accessibility preferences
Shortcut: id, name, type, trigger phrase, target action, parameters, enabled
CommandLog: id, transcript, intent, confidence, status, timestamp, errorReason, userConfirmed
PermissionState: permissionName, granted, requiredForFeature
Routine: id, name, trigger, actions, schedule, enabled

Requirements:
Implement a polished, accessible UI with large touch targets, high contrast, screen reader support, and clear visual states for listening, processing, confirming, success, and failure. Add a robust permissions experience, graceful handling for unsupported commands, offline fallback for a small set of simple actions, and analytics events for onboarding, permission grants, command received, command confirmed, command success, and command failure. Include mock data and a clear service layer so the app can later connect to real backend endpoints.

Deliver the full app scaffold with navigation, state management, reusable components, data models, sample services, and placeholder integrations for Gemini, speech recognition, and Android actions.
