I was wondering if it is possible to set the priority of an IntentService like you can with a Thread. So far I have not found anything.
Just to make it clear - by default IntentService priority is default- Process.THREAD_PRIORITY_DEFAULT because it uses HandlerThread Internally. You can use Process.setThreadPriority(Process.THREAD_PRIORITY_BACKGROUND) in OnHandleIntent(), or whatever the CommonsWare suggested in the answer.
some people raised this as bug. and there is also patch available for this.
