It will be a single thread, taken from a managed thread pool. The argument ellipsis is simply the input to your doInBackground method. As you can see from the example, no threads are spawned in there. If you want to use one thread per URL, you'll have to create a new AsyncTask for each of them.

It is one thread that is looping over the data.

You can do the latter too.

With the 2nd option, you need to take the heap size into account, as the handset only has a limited amount of memory and many parallel threads, all downloading in big buffers may overrun the available memory.
