title: Turn by turn multiple points route navigation Google Maps Intent on Android
body: <p>I am looking for a way to open turn-by-turn navigation on Google Maps. I know that from <a href="https://developers.google.com/maps/documentation/android-api/intents#launch_turn-by-turn_navigation" rel="nofollow noreferrer">this</a> google article it can only be defined by start and end points.</p>
  
  <p><strong>First option (preferred):</strong></p>
  
  <p>I haven't find any intent in Google Maps that does exactly what I want. Does anyone know if there is one?</p>
  
  <p><strong>Second option:</strong></p>
  
  <p>I have tried other ways to reach what I want. I have tried to create a custom route on maps.google.com (from desktop browser) and open it from Android device.</p>
  
  <p>The link has the following format </p>
  
  <blockquote>
    <p><a href="https://www.google.com/maps/dir/37.7851009,-122.4049193/37.7817261,-122.4008209/@37.7815141,-122.4059922,16z/data=!4m19!4m18!1m15!3m4!1m2!1d-122.4055931!2d37.7834466!3s0x808580868ad307fd:0xa75b816ccbe984a0!3m4!1m2!1d-122.4061769!2d37.7812298!3s0x80858086b49a3cfb:0x23f20e98c029217c!3m4!1m2!1d-122.4031591!2d37.7817777!3s0x80858080cb0a7eb1:0xdc77f5df810aebcd!1m0!3e2" rel="nofollow noreferrer">https://www.google.com/maps/dir/37.7851009,-122.4049193/37.7817261,-122.4008209/@37.7815141,-122.4059922,16z/data=!4m19!4m18!1m15!3m4!1m2!1d-122.4055931!2d37.7834466!3s0x808580868ad307fd:0xa75b816ccbe984a0!3m4!1m2!1d-122.4061769!2d37.7812298!3s0x80858086b49a3cfb:0x23f20e98c029217c!3m4!1m2!1d-122.4031591!2d37.7817777!3s0x80858080cb0a7eb1:0xdc77f5df810aebcd!1m0!3e2</a></p>

  <p>Instead of opening turn by turn navigation, it open Google Map Android application with the route displayed on the map. This is the nearest of what I want because there is the button that can show turn-by-turn navigation.</p>
  
  <p>I don't know if it is possible to create link of this type from a collection of (lat,lng) geographical points. I see that data parameter is the one containing the route.
  Does anyone know how to reach it? If it is possible, I think that I can create links in my Android app to open with Google Maps App. (Actually I haven't tried to put this link manually to my app, but I assume this to work.)</p>
  
  <p><strong>Update:</strong>
  I don't want to find a route from point A (start point) to point B (end point). I have all the route from start to finish in geographical coordinates. So, any solution that is of the form direction from A to B are not solution to my problem.</p>
