What arguments are passed into AsyncTask?
I don't understand what I am supposed to put in here and where these arguments end up? What exactly should I put, and where exactly will it go? Do I need to include all 3 or can I include 1,2,20?

Why would I ever use push_back instead of emplace_back?
...ns to avoid copies, emplace_back uses perfect forwarding to send the arguments directly to the constructor to create an object in-place. It seems to me that emplace_back does everything push_back can do, but some of the time it will do it better (but never worse).

... get this kind of SEGV, with a bogus (very small) PC address, 99% of the time it's due to calling through a bogus function pointer. Note that virtual calls in C++ are implemented via function pointers, so any problem with a virtual call can manifest in the same way.
