evernote android-job: When is the right time to set the schedule rules?

I did not find anything about this topic, however I am curious what your recommendations or "best practices" are regarding when to set the rules to schedule the task? For example if I have to schedule a sync job, which should always be there as long as the app runs, where would the

new JobRequest.Builder("...")..
  .build()
  .schedule()

be called?

Thank you

Extending shmakova's answer, you may need to add a condition if your sync job is already scheduled like this:

public static void scheduleJob() {
    if (JobManager.instance().getAllJobRequestsForTag(MyJob.TAG).isEmpty()) {
        new JobRequest.Builder(MyJob.TAG)
                .setPeriodic(900_000L)
                .setRequiredNetworkType(JobRequest.NetworkType.ANY)
                .setPersisted(true)
                .setUpdateCurrent(true)
                .setRequirementsEnforced(true)
                .build()
                .schedule();
    }
}

this will prevent scheduling multiple jobs

You should create JobCreator which will instantiate your Job class like this:

public class MyJobCreator implements JobCreator {

    @Override
    public Job create(String tag) {
        if (MyJob.TAG.equals(tag)) {
            return new MyJob();
        }

        return null;
    }
}

And initialize it in Application.onCreate():

JobManager.create(this).addJobCreator(new MyJobCreator());
MyJob.scheduleJob();

MyJob may look like this:

public class MyJob extends Job {

    public static final String TAG = "my_job_tag";

    @Override
    @NonNull
    protected Result onRunJob(Params params) {
        Intent i = new Intent(getContext(), MyService.class);
        getContext().startService(i);
        return Result.SUCCESS;
    }

    public static void scheduleJob() {
        new JobRequest.Builder(MyJob.TAG)
                .setPeriodic(60_000L) // 1 minute
                .setRequiredNetworkType(JobRequest.NetworkType.ANY)
                .setPersisted(true)
                .setUpdateCurrent(true)
                .setRequirementsEnforced(true)
                .build()
                .schedule();
    }
}
