Utilisation d'un ancien service Web AMF à partir d'une application Android native. Je inclus bibliothèque: flex-messagerie-core.jar et flex-messsaging-common.jarComment se connecter au service Web AMF à partir d'Android natif?
Codel'activité Android:
AMFConnection amfConnection = new AMFConnection();
try{
String url = "http://example.com/cc/messagebroker/amf";
amfConnection.connect(url);
Object result = amfConnection.call("exampleService","foo", "bar");
textView.setText(result.toString());
} catch (Exception e) {
Log.e(TAG, e.getMessage(),e);
}
amfConnection.close();
la connexion exacte même amf fonctionne en Java SE, peut obtenir une réponse correcte . Mais dans Android Je me exception:

J'ai aussi essayé bibliothèque klio-mobile-dataservice, donne la même exception. Alors, comment résoudre cette exception et connecter le service Web AMF à partir de l'application Android native?
