title: How can I use turn by turn navigation in Google Map in Android or what can I use for turn by turn navigation?
body: <p>I developed an app which uses Google Map. I already wrote for <code>getDirections</code> using google map direction API. I am getting LatLng List. But I don't know how can I implement turn by turn navigation like in navigation apps or Uber into my app using Google Map. Or what can I use for this in my app? I am setting marker and polyLine but can't use turn by turn navigation</p>
