android - How can I get turn by turn directions using gps coordinates or waypoints programatically in android

Question

I have an android app that basically takes gps coordinates from where a user travels. I want to be able to take those coordinates and pass them into the navigator so that I can get turn by turn directions for the user. Is there a way to do this in android?

Answer 1

看看Navit- 开源导航系统（在 Android 上运行）。
或RouteMe。两者均基于OpensStreetMap.
但在所有情况下，这都是一个重大项目。
