NotificationJobScheduler Issues

[BillyBoFilly]

Just signed up to this awesome forum! I was wondering if you guys could help me with this problem I'm having...

I have created a Notification and in my SharedPreferences I enabled notifications, but I can't see any notifications popping up in my JobScheduler classes.

NotificationClass...

    import android.app.AlarmManager;
    import android.app.NotificationManager;
    import android.app.PendingIntent;
    import android.app.job.JobParameters;
    import android.app.job.JobService;
    import android.content.Context;
    import android.content.Intent;
    import android.support.v4.app.NotificationCompat;
 
 
    public class NotificationJobService extends JobService {
 
        /**
         * This is called by the system once it determines it is time to run the job.
         * [USER=315340]@param[/USER] jobParameters Contains the information about the job
         * @return Boolean indicating whether or not the job was offloaded to a separate thread.
         * In this case, it is false since the notification can be posted on the main thread.
         */
        [USER=1021285]@override[/USER]
        public boolean onStartJob(JobParameters jobParameters) {
 
            //Set up the notification content intent to launch the app when clicked
            PendingIntent contentPendingIntent = PendingIntent.getActivity
                    (this, 0, new Intent(this, MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);
 
            NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
 
            NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "my_channel")
                    .setContentTitle(getString(R.string.pref_title_notification))
                    .setContentText(getString(R.string.pref_summary_notification))
                    .setContentIntent(contentPendingIntent)
                    .setPriority(NotificationCompat.PRIORITY_HIGH)
                    .setDefaults(NotificationCompat.DEFAULT_ALL)
                    .setAutoCancel(true);
 
            manager.notify(0, builder.build());
            AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
            alarmManager.set(AlarmManager.ELAPSED_REALTIME, System.currentTimeMillis(), contentPendingIntent);
 
            return false;
        }
 
        /**
         * Called by the system when the job is running but the conditions are no longer met.
         * In this example it is never called since the job is not offloaded to a different thread.
         * [USER=315340]@param[/USER] jobParameters Contains the information about the job
         * @return Boolean indicating whether the job needs rescheduling
         */
        [USER=1021285]@override[/USER]
        public boolean onStopJob(JobParameters jobParameters) {
            return true;
        }
    }

Now this is the activity where I set my SettingsActivity. Here is where I schedule the Job. In the onSharedPreferences() method is where I am defining the Job and wanting it to display.

    import android.app.job.JobInfo;
    import android.app.job.JobScheduler;
    import android.content.Context;
    import android.content.SharedPreferences;
    import android.os.Bundle;
    import android.support.annotation.Nullable;
    import android.support.v7.app.AppCompatActivity;
    import android.support.v7.preference.PreferenceFragmentCompat;
    import android.support.v7.preference.PreferenceManager;
 
 
    public class SettingsActivity extends AppCompatActivity implements
            SharedPreferences.OnSharedPreferenceChangeListener {
 
        private static final String TAG = SettingsActivity.class.getSimpleName();
        private static final int JOB_ID = 88;
 
        [USER=1021285]@override[/USER]
        protected void onCreate([USER=1996173]@nullable[/USER] Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
 
            getSupportFragmentManager().beginTransaction()
                    .replace(android.R.id.content, new SettingsFragment()).commit();
        }
 
        [USER=1021285]@override[/USER]
        protected void onResume() {
            super.onResume();
 
            PreferenceManager.getDefaultSharedPreferences(this)
                    .registerOnSharedPreferenceChangeListener(this);
        }
 
        [USER=1021285]@override[/USER]
        protected void onPause() {
            super.onPause();
 
            PreferenceManager.getDefaultSharedPreferences(this)
                    .unregisterOnSharedPreferenceChangeListener(this);
        }
 
        [USER=1021285]@override[/USER]
        public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
            final String notifyKey = getString(R.string.pref_key_notification);
            if (key.equals(notifyKey)) {
                boolean on = sharedPreferences.getBoolean(notifyKey, false);
                JobScheduler jobScheduler =
                        (JobScheduler) getSystemService(Context.JOB_SCHEDULER_SERVICE);
            }
        }
 
        /**
         * loading setting resource
         */
        public static class SettingsFragment extends PreferenceFragmentCompat {
 
            [USER=1021285]@override[/USER]
            public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
                addPreferencesFromResource(R.xml.preference);
            }
 
        }
    }

Any help would be greatly appreciated!

The first thing I would verify is this

public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
                addPreferencesFromResource(R.xml.preference);
            }

Set a breakpoint at this line, run your app in debug mode, and see if it gets hit.
If not, then your shared preference is not being added in the first place.
