Hello,
anybody knows how to remove a polyline from the googlemaps?
I need to redraw one Polyline every change from the Gyroscope, but without removing the markers.
At the moment i use gmap.clear but this also removes all markes. How can i do this?

B4X:
Sub DrawAngle
Dim Distance As Int = 1
Dim Radius As Int = 1
Dim Bearing As Double = Status.AngleX
Distance = (Distance /Radius)
LatB = ASinD(SinD(Status.myPosLat) * Cos(Distance/Radius) + CosD(Status.myPosLat) * Sin(Distance/Radius) * CosD(Bearing))
LonB = Status.myPosLon + ATan2D(SinD(Bearing) * Sin(Distance / Radius) * CosD(Status.myPosLat), Cos(Distance / Radius) - SinD(Status.myPosLat) * SinD(LatB))
gmap.clear
line = gmap.AddPolyline
points.Initialize
line.color=Colors.Red 'Array As Int(255,255,255)
line.Geodesic=True
line.Visible =True
line.Width=2
Point.Initialize(LatB, LonB)
points.Add(Point)
Point.Initialize(Status.myPosLat, Status.myPosLon)
points.Add(Point)
line.points=points
points.Clear
End Sub
