Re: [androidbrasil-dev] Como fazer uma rota no Android

Aew gente, to precisando fazer uma rota em um APP mas não ta saindo da maneira correta...

Com essa implementação aqui está indo de boa mais a rota fica mal traçada.

http://nglauber.blogspot.com.br/2011/10/google-maps-tracando-rotas.html

Quando o trajeto não tem muitas ruas fica de boa.

Com essa implementação aqui está dando erro no Paser

Eu identifiquei que o erro está no método getRoute()

O Log seria esse

O método e esse

public static Road getRoute(InputStream is) {

                KMLHandler handler = new KMLHandler();

                try {

                        SAXParser parser = SAXParserFactory.newInstance().newSAXParser();

                        parser.parse(is, handler);

                } catch (ParserConfigurationException e) {

                Log.i("teste", "catch do Parser");

                        e.printStackTrace();

                } catch (SAXException e) {

                Log.i("teste", "catch do SAX");

                e.printStackTrace();

                } catch (IOException e) {

                Log.i("teste", "catch do IO");

                        e.printStackTrace();

                }

                return handler.mRoad;

        }

A String passada é essa

http://maps.google.com/maps?f=d&hl=en&saddr=49.85,24.016667&daddr=50.45,30.523333&ie=UTF8&0&om=0&output=kml

E no navegador está funcionando perfeitamente

Eu to executando em um Tablet

Alguém já passou por isso ?
