Question

I’m using method scheduleAtFixedRate in my program (Timer class ). It runs every one second, but sometimes this method becomes really fast ( it’s executing 3 – 4 per second ).

However i did some research on web and i found this:

Copied from android developer’s page:

With fixed-rate execution, the start time of each successive run of a task is scheduled without regard for when the previous run took place. This may result in a series of bunched-up runs (one launched immediately after another) if delays prevent the timer from starting tasks on time.

I need fixed timer. It should run only once per x time without any fast executions. Is there any alternative to scheduleAtFixedRate method or, i need to be satisfied with this method?

Answer 1

You could try with a ScheduledExecutorService instead, with more than one thread if your task can take more than 1 sec to run.

The syntax is very similar to Timer but it is a more robust and flexible API.
