How to synchronise adresses and mail folders with Thunderbird for windows

I have just installed Thunderbird for Android on my nearly new Xaomi tablette, and want to sychronise my adresses and some ancient mails that are in sub folders of mail in. Is it possible? I use Thunderbird on my windows mc's since it came out (as with Firefox. Firefox instantly synchronises everything between my 2 windows mc and my Xaomi phone and tablette), Why can't Thunderbird? It has copied the names of the folders but not the files in them!
