How to create a map of public transport routes on android?

Question

Android

Hello. I want to create an interactive map of public transport routes, but what would it look like a metro map. That is, it will contain a minimum of information - transport and some important and tourist points. All this on android
How to proceed?
What I found:
- You can use oms, but I don’t understand how to implement everything I want
- I also found that you can use PhoneGap, and use some kind of java script

Answer 1

Take tiles from the Internet, draw a route on top of them. This is quite feasible without the participation of Android - on the API of some kind of mapping system (Google, Yandex, OSM, etc.), which work quite well even in the built-in browser.
Moreover, 2gis already has a display of transport routes.
