i get myjson string use the mothed Graphic.toJson(graphic) and it's about this
{"attributes":{"id":1,"name":"aa"},"geometry":{"x":121.14829488816405,"y":31.278801530446056,"spatialReference":{"wkid":4326}}}
but when i use the method Graphic.fromJson(parser), they return null;
he is the code :
JsonFactory localJsonFactory = new MappingJsonFactory();
String graphicStr ="{\"attributes\":{\"id\":1,\"name\":\"aa\"},\"geometry\":{\"x\":121.14829488816405,\"y\":31.278801530446056,\"spatialReference\":{\"wkid\":4326}}}";
JsonParser parser = localJsonFactory.createJsonParser(graphicStr);
Graphic g = Graphic.fromJson(parser);
parser.close();
graphicsLayer.addGraphic(g);
when debug g is null.
