I am working over a project and i am facing a strange problem in notification.
Basically i want to play alarm in notification and for that i am adding sound i.e.uri in Notification Builder.
Here is my code:
builder.setSmallIcon(R.mipmap.app_icon).setContentTitle(title)
.setContentText(msg)
.setColor(getResources().getColor(R.color.white))
.addAction(R.drawable.alarm_off, getString(R.string.dismiss), pendingIntent)
.setOngoing(true)
.setSound(Uri.parse(path));
Notification notification = builder.build();
notification.flags |= Notification.FLAG_INSISTENT;
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(WAKE_UP_ALARM_ID, notification);
Notification appears in panel but when i touched the notification panel to scroll down, music stops automatically.
I am unable to understand the scenario.
Please help me to sort out the problem.
Thanks
The flags that are used in notification builder
1.Notification.DEFAULT_SOUND:used to play sound.
2.Notification.FLAG_INSISTENT:this flag is makes your sound to ring continuously until you have done few operations on notification ie,
either you drag the bar or you click the bar.
3.Notification.FLAG_AUTO_CANCEL:this flag is used to automatically cancel the notification after you have seen it
I'm trying to make an alarm app, and I'm really close, but I want the alarm sound to keep playing until the user has manually disabled it via my app (puzzle to turn off alarm type idea). The problem Im having now is that the sound plays up until I pull down the notification drawer, then it stops.
Here is the relevant code:
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setSmallIcon(R.drawable.ic_launcher);
notificationBuilder.setContentTitle(alarm.getLabel());
notificationBuilder.setContentText(alarm.getMessage());
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
notificationBuilder.setSound(alarmSound);
notificationBuilder.setOngoing(true);
Notification notification = notificationBuilder.build();
if(alarm.getVibrate()) {
notification.defaults |= Notification.DEFAULT_VIBRATE;
}
notification.flags = Notification.FLAG_NO_CLEAR | Notification.FLAG_INSISTENT;
notificationManager.notify(2, notification);
I have tried messing around with the flags, but nothing seems to keep it playing...
Thanks for any help in advance.
Found a solution. Had to use a background Service to play the ringtone rather than the notification manager.
So i have created this notification in my activity
Notification n = new Notification.Builder(getApplicationContext())
.setContentTitle("New mail from " + sender)
.setContentText(subject)
.setSmallIcon(R.drawable.notification)
.build();
How can i now show it in status/notification bar along with the sound?
There is some good documentation at android developer site
and have a look at the NotificationManager doc's
Here you go, some code...:
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(mId, n);
Note that it is also a goo idea to add your intend to the notification...
mBuilder.setContentIntent(resultPendingIntent);
To add sound you can use the Notification.Builder.setSound() method.

Use the Notification.Builder.setSound() method.
You can get the default ringtone like this:
Uri uri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
and then set it as notification sound:
Notification.Builder(getApplicationContext()).setSound(uri);
and then after you've built your notification you launch it with:
myNotificationManager.notify(myNotificationId, n);
I am developing a GPS-based app and have just started adding in my UX features such as notifications and progress bars but I'm stuck on using an ongoing notification.
As it is a GPS app, when user tracking is started, I set up an ongoing notification to show that they are being tracked but how do I stop this notification when they tap "stop tracking" in my app? Do I have to tell the NotifyManager something? I'm basically trying to get the functionality that music players have, as in the "playing" notification appears when the user presses play, but when they pause, that ongoing "playing" notification is destroyed.
Also, I've never worked with GPS before but should I be going about this in a Service so that the user won't stop being tracked if my app is taken out of memory by the OS? Or would that not happen?
I haven't done much with notifications but you might try this:
NotificationManager.cancel(id); // Where 'id' is the id of your notification
Replacing NotificationManager with the name of your instance of it, of course.
docs: http://developer.android.com/reference/android/app/NotificationManager.html#cancel%28int%29
Or this:
Notification.Builder.setAutoCancel(true);
http://developer.android.com/reference/android/app/Notification.Builder.html#setAutoCancel%28boolean%29
Start
int id = 01;
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(getResources().getString(R.string.service_header))
.setContentText("Connect to: http://" + httpd.getip() + ":8080")
.setContentIntent(pendingIntent)
.setOngoing(true);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(01, mBuilder.build());
Cancel
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(01);
I have made an app that sets notifications in the drop-down status bar of Android phones. However, there is a bug in my code (sometimes the notifications are set, sometimes they are not). I want to be able TO CHECK (in the code) IF THE NOTIFICATION IS VISIBLE TO THE USER. (i.e. can the user see the notification in the status bar?).
How can I do this? (Thanks in advance).
Sample code is greatly appreciated.

You can't, sorry. Update: Now possible with Android 4.3+ http://developer.android.com/reference/android/service/notification/NotificationListenerService.html#getActiveNotifications()
However, you can always simply cancel() it -- canceling a Notification that is not on-screen is perfectly fine. Conversely, you can always safely call notify() again for the same Notification, and it too will not cause a problem if the Notification is already on-screen.
EDIT:
NotificationManager.getActiveNotifications() was added in API 23 if you don't want to use the NotificationListenerService
Just to put all together. This is how it works
To build a notification,
Notification n = new Notification.Builder(MyService.this)
.setContentTitle("Notification Title")
.setContentText("Notification Message")
.setSmallIcon(R.drawable.myicon).build();
To make a notification sound call setSound() of Notification,
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Notification n = new Notification.Builder(MyService.this)
.setContentTitle("Notification Title")
.setContentText("Notification Message")
.setSound(alarmSound)
.setSmallIcon(R.drawable.myicon).build();
To cancel the notification after user selected and launched the receiver Intent, call setAutoCancel(),
Notification n = new Notification.Builder(MyService.this)
.setContentTitle("Notification Title")
.setContentText("Notification Message")
.setSound(alarmSound)
.setAutoCancel(true)
.setSmallIcon(R.drawable.myicon).build();
To make sound/vibrate only once for a particular notification use Notification.FLAG_ONLY_ALERT_ONCE. With this flag, your notification will make sound only once till it gets cancelled and you can call notify() as many times as you want with the notification id. Note that if you call cancel() or if user cancelled the notification or auto cancelled, notify() call will make the notification sound again.
n.flags |= Notification.FLAG_ONLY_ALERT_ONCE; // Dont vibrate or make notification sound
Finally to put the notification on notification panel,
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(notification_id, n);
Note that notification_id here is important if you want to use the notification effectively.( to keep single sound/vibration for a notification or to cancel a specific notification).
To cancel a particular notification,
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.cancel(notification_id);
You can cancel() a notification even if it doesn't exist or you can call notify() as many times as you want with the same id. Note that calling notify with different id will create new notifications.
So, regardless of whether the notification exist or not, if you call notify() again with the correct notification_id with the Notification.FLAG_ONLY_ALERT_ONCE flag set, you can keep your notification alive without disturbing the user with repeated sounds.
You need to set an id for each notification you make.
so you make a notification ..
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, notId + selectedPosition, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, rightNow.getTimeInMillis() - offset, pendingIntent);
Notification notification = new Notification(R.drawable.icon, "TVGuide Υπενθύμιση", System.currentTimeMillis());
NotificationManager manger = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
notification.setLatestEventInfo(context, "Κανάλι: " + b.getString("channel"), "Εκπομπή: " + showname, pendingIntent);
manger.notify(notId, notification);
to clear it..
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,notId, intent, 0);
pendingIntent.cancel();
and to check if active..( existAlarm returns null if no pending intent available)
public PendingIntent existAlarm(int id) {
Intent intent = new Intent(this, alarmreceiver.class);
intent.setAction(Intent.ACTION_VIEW);
PendingIntent test = PendingIntent.getBroadcast(this, id + selectedPosition, intent, PendingIntent.FLAG_NO_CREATE);
return test;
}
So everything comes down to initialize an ID for each notification and how you make it unique.
A new method is introduced to the NotificationManager class in API 23:
public StatusBarNotification[] getActiveNotifications()
There exists a flag for that.
Notification notification = new Notification(icon, tickerText, when);
notification.flags |= Notification.FLAG_ONLY_ALERT_ONCE;
FLAG_ONLY_ALERT_ONCE:
...should be set if you want the sound and/or vibration play each time the notification is sent, even if it has not been canceled before that.
Although, the notification will blink when it is sent again, but there won't be any sound or vibration.
It's possible now to check notifications outstanding in android 4.3 upwards
See here:
http://developer.android.com/reference/android/service/notification/NotificationListenerService.html#getActiveNotifications()
It seems that from Android M (API 23) it is possible to get your process like that, without using NotificationListenerService nor requiring additional permissions:
notificationManager.getActiveNotifications()
As of Android Marshmallow (API 23), you can recover a list of active notifications posted by your app. This NotificationManager method is getActiveNotifications(). More info here: https://developer.android.com/reference/android/app/NotificationManager.html#getActiveNotifications()
