Notification not sent by JobService

So I have a notification set up in my JobService.class and I know for sure that it works. The problem is that I don't think my JobService is ever getting called. I want my app to check the database every couple hours and if it matches certain criterias it will send a notification. I start my JobService like this in my MainActivity:

JobService.class

JobService

JobService

MainActivity

ComponentName componentName = new ComponentName(MainActivity.this, JobService.class);
JobInfo info = new JobInfo.Builder(6484, componentName)
.setPeriodic(1000 * 60 * 15)
.build();

JobScheduler scheduler = (JobScheduler) getSystemService(JOB_SCHEDULER_SERVICE);
if (scheduler != null) {
scheduler.schedule(info);
}


And this is my JobService since it's too long. I cut off the code for the notification parts because it's too long.

JobService

@Override
public boolean onStartJob(JobParameters jobParameters) {
{//when it matches the criteria and the notification is sent

jobFinished(jobParameters, false);
}
return true;
}

@Override
public boolean onStopJob(JobParameters jobParameters) {
if (databaseReference != null && valueEventListener != null) {
databaseReference.removeEventListener(valueEventListener);
}

return false;
}


PS. I'm sure my notification works because before I was using the Service class and it would send the notification. I just had to switch because it would not check for updates in the background.
