How to preserve context in JobScheduler

I have a job as under

public class MyPeriodicJob extends JobService{
    @Override
    public boolean onStartJob(JobParameters jobParameters) {

        // do something (but context is needed)

        return false;
    }

    @Override
    public boolean onStopJob(JobParameters jobParameters) {
        return false;
    }
}

It is started in MainActivity

private void scheduleJob(){
        JobScheduler jobScheduler = (JobScheduler)getApplicationContext()
                .getSystemService(JOB_SCHEDULER_SERVICE);

        ComponentName componentName = new ComponentName(this,
                MyPeriodicJob.class);

        JobInfo jobInfo = new JobInfo.Builder(1, componentName)
                .setPeriodic(86400000)
                .setPersisted(true).build();
        jobScheduler.schedule(jobInfo);
    }

The device may restart but the job is expected to persist. How can I pass context (which must persist) to the MyPeriodicJob ?
