How to cancel scheduler job when alarm fire off

Question

I have 2 alarms in one alarm I'm starting job scheduler service that sends notifications every 30 minutes and at the second alarm I want to cancel this scheduled job service, also I'm sending notification on main thread I didn't make separate thread in job service, here is my code:

This is my jobinfo object and I'm executing this method when broadcast of start alarm fires off

public static void Scheduler(Context context){

     float duration = NotificationUtills.NotificationCounter();

     ComponentName componentName = 
     new ComponentName(context , ClsJobService.class);

    JobInfo.Builder builder =  new JobInfo.Builder(0, componentName)
            .setPeriodic(5000);


    JobScheduler jobScheduler = 
    (JobScheduler) context.getSystemService (Context.JOB_SCHEDULER_SERVICE);

    jobScheduler.schedule(builder.build());
}

And this is job service

public class ClsJobService extends JobService {

@Override
public boolean onStartJob(JobParameters params) {

    //logic for building and sending notification
    NotificationUtills.notificationBuilder(getApplicationContext());
    return true;
}

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

Is it alright not to create separate thread?

Also how can i cancel this scheduled job when second alarm fires off?

It is, as long as your Notification building logic does not do anything time consuming that might hurt the responsiveness of the app.

You can call the cancel() method of JobScheduler. It takes the job ID as a parameter. This has to be the same job ID you passed to the JobInfo.Builder constructor (0 in your code).
