Offline AI Tutor on Android: Gemma 3n + MediaPipe GenAI with Local RAG+CAG implementation

Demonstrating an offline Android AI tutor using Gemma 3n via MediaPipe, with local text ingestion, SQLite semantic indexing, and on-device retrieval‑augmented generation.

Overview

I’ll live-demo an offline AI tutor running entirely on an Android phone using Gemma 3n via MediaPipe. The app ingests local text files, chunks and semantically indexes them in SQLite, and performs retrieval-augmented generation with on-device embeddings.
Please suggest what from code would be interesting to present..
