gmap.AddMarker(37.772323, -122.214897, "Hello!!!")

                Dim line As Polyline

                Dim point As LatLng
                line=gmap.AddPolyline
                Points.Initialize
             
             
                line.Color=Colors.Blue
                line.Geodesic=True
                line.Visible =True
                line.Width=2
                'line.ZIndex=0
                point.Initialize(37.772323, -122.214897)
                Points.Add(point)
                point.Initialize(21.291982, -157.821856)
                Points.Add(point)
             
                line.Points=Points
                Dim cp As CameraPosition
                cp.Initialize(36, 15, gmap.CameraPosition.Zoom)
                gmap.AnimateCamera(cp)

This code creates a rectangular lab between two tags


I want a code that makes a winding line on the street direction between a sign and my location

It is not about the code, but it all depends how many points you have between the start and end. IF you have 2 points you will have a straight line if you have 50 points that follow the road - you will get the polyline (winding line).
If you use google Geocoding API (see this thread https://www.b4x.com/android/forum/t.../b4x-google-geocoding-rest-api.83870/#content) you will get a lot of points between the start and end point - which means you can get the better polyline.

if the idea is useful for you

Google Maps - Alternative Markers

The standard 'teardrop' marker available in Google Maps that shows the snippet when tapped is pretty easy to use, but I am looking for something permanently visible.... Like a little rectangle maybe 3%x by 3%y slightly offset from the waypoint. Ideally something like a 'speech bubble' that can...

you must work with multi-markers and not polylines.

and the marks are a bitmap or a radius circle

[alfaiz678]

is what you want ??

Zigzag line is between my location and another Mark on the map
Like the one in the picture above

 

[TILogistic]

If I understand you want a winding line between these two positions-

 

[TILogistic]

You are searching for the route between an address and its location.

and draw a winding line of the route??

example: APP
Delivery or Uber
