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));

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.

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()
}

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

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.
