App Engine Verbundenes Android-Projekt C2DM-Verbindungsfehler - Android, Google-App-Engine, Android-c2dm

Ich versuche gerade, eine Android-App so zu gestaltenkommuniziert mit Google App Engine. Nach der Installation des Plugins für Google App Engine habe ich versucht, vor dem Start etwas zu überprüfen, ob die C2DM-Verbindung mit dem Emulator funktioniert. Wenn ich jedoch die Verbindung mit dem Emulator teste, stellt das Gerät keine Verbindung zum Server her. Muss ich noch etwas ändern, damit es funktioniert? Ich habe versucht, die IP-Adresse zu ändern, die von der Anwendung verwendet wurde, aber immer noch ohne Ergebnis. Bei jedem Verbindungsversuch erhalte ich folgende Fehlermeldung:

Sie müssen wahrscheinlich das folgende Standard-JVM-Argument hinzufügen

-XX:-UseSplitVerifier

In Eclipse:

Window -> Preferences -> Installed JREs -> then add the default parameter
