Android Job Scheduler

Question

I was learning about JobScheduler with a Tutorial from 2015, and when I was creating a class of this service,it complains asking me to put the annotation @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP), which means, doesn't work for old versions? And if it is, GCMNetworkManager would be the one ?

Answer 1

which means, doesn't work for old versions?

Yes annotation specifies that API wont work under LOLLIPOP version

And if it is, GCMNetworkManager would be the one ?

Alternatives to JobScheduler are

• AlarmManager
• GCMNetworkManager
• SyncAdapter

You should choose one that suits your need with minimal device resource utilisation.

Note: Avoid using services that run perpetually or perform periodic work, since they continue to use device resources even when they are not performing useful tasks.
