Notification created in BroadcastReceiver doesn't work, on app close

This is my code. It works fine, if I use this in a separate Android studio project. But when I integrate the code to another project it is causing a problem. If app is open I am able to receive the notifications. But on app close, the notifications are not received.

Also I have observed one thing - I set my alarm at 1:10 (let's say) and close, and re-open the app at 1.09. I am receiving the notification at 1.10 !!.

I am not able to identify what's happening. Please tell me even if am doing silly mistake, Thank you. 

public class BroadCast {

public void broadcastIntent(int selected, Context context, long userMilli) {
    Intent intent = new Intent(context.getApplicationContext(), ReminderReceiver.class);
    Bundle bundle = new Bundle();
    bundle.putInt("selected", selected);
    intent.putExtras(bundle);
    intent.setAction("android.media.action.DISPLAY_NOTIFICATION");
    intent.addCategory("android.intent.category.DEFAULT");

    Calendar calendar = Calendar.getInstance();
    long curMilli = calendar.getTimeInMillis();

    PendingIntent pendingIntent = PendingIntent.getBroadcast(context.getApplicationContext(), selected, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

    if(Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT)
        alarmManager.setExact(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + (userMilli-curMilli), pendingIntent);
    else
        alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + (userMilli-curMilli), pendingIntent);
}
}

Above code creates an intent and broadcast using alarmManager.

public class ReminderReceiver extends BroadcastReceiver {

public ReminderReceiver() {
}

@Override
public void onReceive(Context context, Intent intent) {
    Bundle bundle = intent.getExtras();
    int selected = bundle.getInt("selected");
    sendNotification(context, selected);
}

private void sendNotification(Context context, int selected) {
    String notificationContentText = "String to display";

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

    builder.setSmallIcon(R.drawable.alarm)
            .setContentTitle("Title")
            .setPriority(Notification.PRIORITY_MAX)
            .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
            .setContentText(notificationContentText)
            .setColor(Color.rgb(58,95,205));

    notificationManager.notify(selected, builder.build());
}
}

Above code building the notification

This is my AndroidManifest file

    <receiver
        android:name=".ReminderReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="android.media.action.DISPLAY_NOTIFICATION"/>
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>

It was not the problem of BroadcastReceiver or the Service. I had to change my notification settings in my mobile. I use Asus, there you have to check power management option. If it is in power saving mode then the notifications are denied on app close.
