iOS Question gmap add polyline problem

[tufanv]

Hello

I am using below code to add polyline to google map ( at locationchanged event )

direction = gmap.AddPolyline

direction.Color=Colors.blue
place.Initialize(location1.Latitude, location1.Longitude)
points.Add(place)
direction.points = points

this code works perfect with b4a but with b4i polyline is not drawen on to google map.

What is the mistake i am doing ?

Please use [code]code here...[/code] tags when posting code.

I tried it with this code:

Sub gmap_Click (Point As LatLng)
   Dim points As List = pl.Points
   points.Add(Point)
   pl.Points = points
End Sub

Where pl is a global polyline that was previously added and it works. Each time you click on the map a line is drawn.

I am nearly using the sam code with you but you use it on gmap click i use it on loc changed. but cant get the polyline drawen. In the logs i can get the "place" latlong values and can get the direction value which shows

I dont know if it is a problem but there is a null in front of the direciton log.

You can see in the lists that the same LatLng object was added multiple times.

Add:
Dim place As LatLng to your code.
It will create a new instance each time.
