Android Daily Overview

Android Daily Overview is an Android application that uses AI to process incoming SMS messages and notifications and display them in a dashboard in a form of a summary and proposed actions for calendar and/or alarms.

The background service is collecting incoming messages and notifications, categorizing and vectorizing them using MobileBERT into an ObjectBox database. The final summary and proposed actions for a user are generated from a dashboard using Gemma-4 E4B model, using LiteRT-LM. This split of competencies helps battery life a lot, not engaging the big brain unless necessary.

Features

• Ingestion Layer: Captures data from multiple sources:

  • Real-time SMS: SmsReceiver (BroadcastReceiver) intercepts incoming SMS.
  • Real-time Notifications: NotificationListener (NotificationListenerService) captures system notifications.
  • Background SMS Sync: SmsSyncWorker performs a historical scan of SMS on application startup to ensure no missed information.

• Processing & Intelligence Layer:

  • Categorization: MediaPipe (MobileBERT) TextClassifier assigns a category (e.g., Finance, Social).
  • Embedding: MediaPipe (MobileBERT) TextEmbedder creates vector embeddings for RAG.
  • Action Extraction: For actionable candidates (like invoices or appointments), the LiteRT-LM (Gemma-4) engine extracts structured JSON data.
  • Retention Assignment: Each message is assigned a retentionCategory based on its content (e.g., OTPs are VOLATILE, invoices are ACTION_LOCKED).

• Persistence & Maintenance Layer:

  • ObjectBox: Stores MessageEntity and ActionDraft reactive objects.
  • Data Retention: CleanupWorker runs hourly to maintain database health:
    • Expired Data: Removes messages past their expiryTimestamp (e.g., 1 hour for VOLATILE).
    • Resolved Actions: Removes ACTION_LOCKED messages once their corresponding action is confirmed or dismissed.

• User Interaction Layer:

  • Reactive Dashboard: Automatically displays new ActionDraft entries.
  • Action Execution: ActionManager uses system Intents to launch the Calendar or set Alarms, ensuring the user remains in control.
