Android Question Route between multiple points google maps

[fernando.oliboni]

Does anyone have an example in B4A that shows the route between several points? I have addresses, I don't have latitude and longitude.
Thank you very much
Fernando

Google has an Api for that.
Try to use that Api.

Thank you for the information. I'll try to use it, I'm not very good at creating from scratch without an example, but I'll try.

Option 2:
if you have the addresses, find the latitude and longitude and draw a polyline between the points.
use:

Here's a demo of how to use the nominatim geocoding API for free. Note: There are other geocoding options if you want to know, leave your comments. Demo file attached Sub GeoCoderNominatim(Query As String) As ResumableSub Dim ResultURL As String Dim j As HttpJob Dim Parameter() As...

As the package appears to be invalid, the app was not installed

 

[Serge Bertet]

In the project B4XMap there is an example how to get coordinates from address (in B4XMainPage).

My goal is to get routes between addresses and not get coordinates from addresses

 

[klaus]

But, to get a route, you need coordinates !!!
This means that you need to convert the addresses to coordinates before calculating a route.
