O seguinte exemplo de código demonstra como obter as coordenadas geográficas para um endereço usando uma solicitação assíncrona de geocodificação. Mesmo que a solicitação especifique somente uma rua, o servidor de geocodificação pode retornar um conjunto relevante de coordenadas por causa do contexto geográfico que é incluído com a solicitação. Quando o aplicativo recebe os resultados da pesquisa, ele exibe a latitude e a longitude na tela.
