title: Having multiple AsyncTasks and running multiple ones
body: <p>I have an Asynctask to fill up a ListView already and depending on the selected item
  my next step would be download an image from a different url depending on the item selected
  would I have to make another private class that extends Asynctask to get the image 
  also since I have an itemOnClickListener and if I call .execute() would it cause problems with having multiple Asynctask running</p>
