Hi CSH,
I know, and I'll make a document on it soon,
at the time I'm so busy, and because of integration, I couldn't post the whole solution,
But I'll make a sample project, and implement simple file tarnsfer solution there for android using asmack, to be helpfull for others.
I'll try to work on different situations that will cause problem and make a list to resolve each problem by help of other people who faces problems with file tarnsfer on android.
As you could see my problem was somthing else: The Receiver receives file transfer query but had no reaction, Listener didn't triggered.
