Android intentService, how to skip to the next task in the queue?

i have an activity that call an intent service.

The intentService download files from int开发者_开发知识库ernet in backgrounf, but i want to be able to abort a specific download.........

So let's say thta i put 5 files in queue: file 1,2,3,4,5

The intent service start downloading the number 1. Is there a way to say to the intent service abort what you are doing at the moment in the method handle event (in this case downloading file 1) and start downloading the next one?

Is it possible to removre element from the queue, so for example while is downloading file 1, remove the file 4 from the queue so that after the number 3 goes straight to the 5?

Tnx
