I'm not sure why you're asking how to do it in AsyncTask, you're already
doing it in an AsyncTask ...
Also not sure why you're asking about security, what exactly do you want to
secure here?
Both of these are not related to the first issues you described which have
to do with your HTTP client implementation and nothing to do with the
AsyncTask itself... for these anyhow, you just need to increase the default
values for timeouts.
Either way, you should really refactor your code since it has some
fundemental issues... any failure in the process will require you to
restart the whole thing... if you fail at the last table, you'd have to
retrieve all the data beforehand again until you'd get to that table (even
though all previous tables are already up to date). Even without seperating
those into multiple concurrent tasks, you should at least provide a
cache/restore/failover machenism.
