Hello!
In my case listeners are registered within adapter (so any changes are
still going through method, part of which was in my previous email).
I've already had an idea to manually implement things that I thought
AsyncTask does for me, e.g. creating looper, handler, runnable etc.
So if you tell it works for you, maybe the cause lays within AsyncTask
implementation (haven't investigated it yet).
Anyways, thanks for sane response.

God, grant me the serenity to accept the things I cannot change,
courage to change the things I can,
and wisdom always to tell the difference.
