GeometryException when drawing a line on the map

[_lkerArg_n]

I tried to draw a line on a graphic layer added to map with the lines of code below. I get a geometry exception. What am I doing wrong?

                           Segment segment = new Line();    segment.setStart(startPoint);    segment.setEnd(endPoint);        Log.d("SEGMENT", "x: " + segment.getStartX() + "y: " + segment.getStartY());        Symbol lineSymbol = new SimpleLineSymbol(Color.BLUE, 4);    someGraphicsLayer.addGraphic(new Graphic(segment, lineSymbol));

I did what I want to by using Polyline.

Polyline poly = new Polyline();
poly.startPath(startPoint);
poly.lineTo(endPoint);
   
allyGraphicsLayer.addGraphic(new Graphic(poly, new SimpleLineSymbol(Color.BLUE, 5)));

Still i wonder what did I do wrong in the code in the previous post.

I have seen the exact same error, and would also like to know what is wrong with the above code.

mggl,

Unfortunately I can not compile your code now, but try to use Polyline when creating a Graphic.

try
{
    Segment segment = new Line();
    segment.setStart(startPoint);
    segment.setEnd(endPoint);
    Log.d("SEGMENT", "x: " + segment.getStartX() + "y: " + segment.getStartY());

    Polyline pLine = new Polyline();
    pLine.addSegment(segment, true);
   
    Symbol lineSymbol = new SimpleLineSymbol(Color.BLUE, 4);
    int addedGraphicId = someGraphicsLayer.addGraphic(new Graphic(pLine, lineSymbol));
    Log.d("Class/activity name for logging", "Graphic added id=" + addedGraphicId);
}
catch (Exception ex)
{
    // log exception ex.getMessage()
}

When you specify a Graphic you've to provide a "Geometry". IMO "Segment" itself isn't a Geometry, it's only part of it within polylines or polygons.
So, for graphics you should use Point, Polyline or Polygon.

Sebastian,

There are no any documentation from ESRI developers, where Segment is not a Geometry!

Also no any documentation about "witch Geometries types can be used with Graphic".

Finally:

So, for graphics you should use Point, Polyline or Polygon.

you right, but I did not find any documentation about it.
