问题
I'm trying for sharing files using asmack-2010.05.07.jar, I'm sending successfully but receiving 0kb file with ExecutionException.
My sending and receiving code is:

String toName = to + "@" + getResources().getString(R.string.service)
+ "/Smack";
transfer = manager.createOutgoingFileTransfer(toName);
Log.i(TAG, "send-TO: " + toName);
// Send the file
try {
File myFile = new File(PICKUP_LOC);
if (myFile.exists()) {
Toast.makeText(MyChat.this, "File Exist---", 1).show();
transfer.sendFile(myFile, "You won't believe this!");
} else {
Toast.makeText(MyChat.this, "NOt Exist---", 1).show();
}
} catch (XMPPException e) {
e.printStackTrace();
}
new AsyncTask<Void, Void, Void>() {

}

System.out.println("Cancelled!!! " + transfer.getError());
}
try {

return null;
};

回答1:
As we discussed here - Smack have some bugs in file transfer implementation: in you case initiator offered bytestreams and ibb methods, responder accept both (which is wrong) methods, on the next trip initiator offer bytestreams streamhosts, responder selects one, and there file transfer should start with selected streamhost. But initiator wrongly starts ibb method(sic!). You can try call FileTransferNegotiator.IBB_ONLY = true; in your code, but strongly recommended to submit bug report to Smack developers.

I think you got your solution already.
Since I suffered of this problem badly and found the solution from this site ,I decided to share it here.
The problem is you need to modify asmack library to increase the timeout value in createIncomingStream() method in FaultTolerantNegotiator class which is in package org.jivesoftware.smackx.filetransfer package.
I downloaded the source code of asmack-android-6-source-0.8.1.1 and modified the source according to the link I provided. It works like a charm!
