From my experience you probably need:
- Offline map: Mapsforge
- Offline routing: GraphHopper
- Turn by turn instructions: GH produces them, check its API
- Voice navigation: Android has text-to-speech (provided it supports
your language)
- Live traffic cannot be entirely offline. You can check Peter's posts
about that here

and here
