B4A Question OSMDroid get geopoints from PathOverLay - RB Smissaert Jun 5, 2018Using OSMDroid 4.1.
It looks there is no way to get the geopoints (OSMDroid_GeoPoint) that were added to a OSMDroid_PathOverlay. It isn't really a problem as I can run a parallel list or array, but it
seems strange.
Am I overlooking something?

You should stay with using the List or Array...

Java Question Passing B4A List as ArrayList - warwound Nov 16, 2012
}
Normally i'd create a wrapper method that accepts a B4A List or Array of GeoPoint objects, and..., the underlying GeoPoint objects are added to the List so WayPoints is an unparameterized ArrayList of GeoPoint objects.
I set a breakpoint and see:

The GeoPoint can use units... WayPoints As List

B4A Question Problem updating view - RB Smissaert Jun 17, 2018Using OSMDroid 4.1 and have a TouchOverLay to add GeoPoints to a PathOverLay.
Both OverLays are added to a MapView, named MapView1.
Sub TouchOverLay1_Click(GeoPoint1 As OSMDroid_GeoPoint) As Boolean
AddAreaPoint(GeoPoint1)
Return(False)
End Sub
Sub AddAreaPoint(GeoPoint1...
PathOverLay1Points.Add(GeoPoint1)
PathOverlay1.AddPoint(GeoPoint1)

This works fine and the GeoPoints are added OK. Problem it doesn't show directly in the MapView.

B4i Question Google Maps Project - Calculating Distances in iOS - RichardN Sep 17, 2016I am translating a Google Maps based B4A project over to B4i. In Android I used the OSM_Droid library to include the Geopoint object calculating the distance between two waypoints thus:
Dim DistanceBetween As Long = Geopoint1.GetDistanceTo(Geopoint2)
Is there a convenient method of doing the same thing in B4i ???...
