Hello, I have a few questions about the file transfer extension. I’ll go on record saying that I know I should RTFM, but it would save me a tremendous amount of time to not have to intimately understand each of the underlying XEPs (that’s why I’m using this API ).
And now, for my questions.
Does the SMACK file transfer extension send binary data directly between two endpoints (out-of-band I think it’s called) versus through the XMPP server? If so, is it usually pretty reliable/fast?
Can downloads be resumed as part of the API?
What’s the difference between this implementation and Jingle really? Is one better than the other, or more appropriate for certain scenarios?
