We don't directly support GPX data, but its pretty easy to write your own importer. If you look at the file format / specification you will see all the data is XML.

https://wiki.openstreetmap.org/wiki/GPX

So if you can read a track as shown in the link above you will set a set of points which make up a track.

<trk><name>Example gpx</name><number>1</number><trkseg> <trkpt lat="46.57608333" lon="8.89241667"><ele>2376</ele><time>2007-10-14T10:09:57Z</time></trkpt> <trkpt lat="46.57619444" lon="8.89252778"><ele>2375</ele><time>2007-10-14T10:10:52Z</time></trkpt> <trkpt lat="46.57641667" lon="8.89266667"><ele>2372</ele><time>2007-10-14T10:12:39Z</time></trkpt> <trkpt lat="46.57650000" lon="8.89280556"><ele>2373</ele><time>2007-10-14T10:13:12Z</time></trkpt> <trkpt lat="46.57638889" lon="8.89302778"><ele>2374</ele><time>2007-10-14T10:13:20Z</time></trkpt> <trkpt lat="46.57652778" lon="8.89322222"><ele>2375</ele><time>2007-10-14T10:13:48Z</time></trkpt> <trkpt lat="46.57661111" lon="8.89344444"><ele>2376</ele><time>2007-10-14T10:14:08Z</time></trkpt> </trkseg></trk>

I've hard coded the points into a polyline as shown:

// points for the track (remember that longitute is X and latitude is Y! Point pt1 = new Point(8.89241667, 46.57608333, 2376, SpatialReferences.getWgs84()); Point pt2 = new Point(8.89252778, 46.57619444, 2375, SpatialReferences.getWgs84()); Point pt3 = new Point(8.89266667, 46.57641667, 2372, SpatialReferences.getWgs84()); Point pt4 = new Point(8.89280556, 46.57650000, 2373, SpatialReferences.getWgs84()); Point pt5 = new Point(8.89302778, 46.57638889, 2374, SpatialReferences.getWgs84()); Point pt6 = new Point(8.89322222, 46.57652778, 2375, SpatialReferences.getWgs84()); Point pt7 = new Point(8.89344444, 46.57661111, 2376, SpatialReferences.getWgs84()); // collection for the points PointCollection points = new PointCollection(SpatialReferences.getWgs84()); points.add(pt1); points.add(pt2); points.add(pt3); points.add(pt4); points.add(pt5); points.add(pt6); points.add(pt7); // create polyline from the points in the collection Polyline trackGeometrty = new Polyline(points); // graphic overlay in a map view (could be a scene view for 3D) graphicsOverlay = new GraphicsOverlay(); mapView.getGraphicsOverlays().add(graphicsOverlay); // symbol for line SimpleLineSymbol lineSymbol = new SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, 0xFF00FF00,5); // graphic from style and polyline Graphic graphic = new Graphic(trackGeometrty, lineSymbol); // finally add graphic to graphic overlay graphicsOverlay.getGraphics().add(graphic);

The end result is this:

So all you need to do is read the xml file remembering that longitude is X and latitude is Y as they are often mixed up.

Does this help?
