What is JobIntentService and where should I use this?

Umesh Chandra

Hi,

I want to know about the JobIntentService and Where should I use this? I have used IntentService in my applications and I want to use JobIntentService but I don't know what are the issue with IntentService?

I have read some articles but still it is not clear.

According to the Android's document,

JobIntentService is a helper for processing work that has been enqueued for a job/service. When running on Android O or later, the work will be dispatched as a job via JobScheduler.enqueue. When running on older versions of the platform, it will use Context.startService.

It uses the JobScheduler function on Android 'O', but runs as a background service to emulate JobScheduler on pre-O. The JobIntentService has the following characteristics:
On Android N and below devices, the background service starts immediately and the loaded jobs are executed sequentially. This ensures backward compatibility with the same code.
In Android O and later, jobs loaded through JobScheduler are executed sequentially. If you want other conditions, JobIntentService doesn’t fit it.
You don’t need WakefulBroadcastReceiver to use Wakelock when running on pre-O, because JobIntentService would manage Wakelock for you. This prevents writing wrong code such as battery drain due to not releasing Wakelocks.

The JobIntentService works in the same way as a Service however it enqueues the work into the JobScheduler on compatible Android targets. This means you can easily convert your Services and IntentServices into aJobIntentService and keep the same functionality.
