回答1:

Implementation looks buggy, e.g.

<feature xmlns="http://jabber.org/protocol/feature-neg">
        <x xmlns="jabber:x:data" type="submit">
            <field var="stream-method">
                <value>http://jabber.org/protocol/bytestreams</value>
                <value>http://jabber.org/protocol/ibb</value>
            </field>
        </x>
    </feature>

is wrong reply, because XEP-0095 say:

If acceptable the Receiver MUST select one of the presented stream types to use.

Try to use only one stream method and/or submit bugreport to Smack.



回答2:

First, thanks for the detailed question. That makes it easy to get an idea what could be wrong. While vitalyster is right, the stanza is a violation of the spec, I don't think this is the cause for the problem.

What looks wrong is that we don't see any result IQs for the set IQs that carry a data element, ie the stanza of Example 7 in XEP-47 is missing. That's all I can say with the provided information. I suggest you grab a debugger to find the root cause. Good that (a)Smack is open source

Edit: You call SmackAndroid.init(Context) as aSmacks README tells you to do, or not?
