openfire asmack+android 发送消息 501错误

// mConn is an XMPPConnectionFileTransferManager  manager = new FileTransferManager(mConn);OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer("[e-mail]");transfer.sendFile(new File(fname), "File for the operator");

会出现

<error type="cancel" code="501"><feature-not-implemented...

 

 

OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer([e-mail]);

替换成：

String to = mConn.getRoster().getPresence("[e-mail]").getFrom();OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(to);
