From the tutorials available on the topic, I was not able to compile. Do we need to download the ksoap2 libs and is that allowed within android apps to import external jars?

Pls provide me some step by step instructions to be able to call a webservice from within Android app.

Q2 is has anyone tried push service to android apps, is there a way to setup a listener on Android to which external apps can push info (ofcourse after registering and other security handshakes) or can one of existing android services be used or extended for this purpose?
