jobscheduler: how to reschedule a task after it's have finished?

I can't find how to reschedule a task after it's over. When I finish a job (just calling jobFinished in the main thread) how can I reschedule the same job ? The problem is that jobFinished is not executed immediately and if I schedule a new task with the same id, then the current job will be canceled (even if in fact it's finished) and it'll call the onStopJob procedure
