title: some kind of queue for asynctask
body: <p>Hello
  I have ListView with list of files. i click item and start to download this file in asynctask.
  then i click another one and it must be put in queue, wait for that file and start ot download after it finishes. i can make some class that will hold all clicked links, and pass it to asynctask downloading part? and than somehow process them. but want to know is it the right way?
  any links of sugestions? thanks </p>
