Buenas, estoy intentando leer un XML online, pero al cargar el evento que se conecta al servidor me suelta lo siguiente:

y no tengo manera de solucionarlo.


El error debe saltar en esta parte

try {
SAXParser parser = factory.newSAXParser();
LeerXml handler = new LeerXml();
parser.parse(this.getInputStream(), handler);
return handler.geteventos();

} catch (Exception e) {
throw new RuntimeException(e);
}
}

gracias de antemano

Caused by: android.os.NetworkOnMainThreadException...

Estás intentando hacer operaciones de entrada/salida o red dentro del hilo principal. Prueba a utilizar un AsyncTask.

siento no haber respondido antes.

Gracias por tu respuesta providez,

pero como tendria que meter en el asynctask el codigo¿?




public ArrayList<ElementosXML> parseXML() {
SAXParserFactory factory = SAXParserFactory.newInstance();

try {
SAXParser parser = factory.newSAXParser();
LeerXml handler = new LeerXml();
parser.parse(this.getInputStream(), handler);
return handler.geteventos();

} catch (Exception e) {
throw new RuntimeException(e);
}
}



// Realiza el Stream del XML vía http
private InputStream getInputStream() {
try {
return rssUrl.openConnection().getInputStream();

} catch (IOException e) {
throw new RuntimeException(e);
}
}


esta es la parte del codigo, como haria?

gracias de antemano
