Jetpacks for you and I
summary
A live demo shows an app that fetches 20 Pokémon via Retrofit and Glide, then eliminates repeated network calls by moving logic into ViewModel + LiveData so rotation no longer triggers extra HTTP requests, with savedInstanceState size noted as 50 KB. Navigation uses Navigation SafeArgs for type‑safe argument passing. Local persistence uses Room (PokemonDB) with an autogenerated primary key and AsyncTask writes; the app works end‑to‑end and code is on GitHub.
