How to receive notification when the application is closed?

I'm making an android application, and I want to receive notifications when the application is closed, how can I do that? I've read also other posts where people ask it but i can't understand how to make it work, could you please try to explain this better?
I've also tried to make a countdownTimer and make the application do something when the timer reaches the 0 but it didn't work, 'cause obviusly when I close the application, I close the timer too.

use this code to make in app notification
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher) // notification icon
.setContentTitle("Notification!") // title for notification
.setContentText("Hello word") // message for notification
.setAutoCancel(true); // clear notification after click
Intent intent = new Intent(this, MainActivity.class);
PendingIntent pi = PendingIntent.getActivity(this,0,intent,Intent.FLAG_ACTIVITY_NEW_TASK);
mBuilder.setContentIntent(pi);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, mBuilder.build());

NotificationCompat at a time

I want to show notification at defined time. I use "setWhen()". But any argument of setWhen() is ignoring and notification always showing instantly. What I did wrong? My code:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setWhen(???)
.setSmallIcon(R.drawable.app_icon)
.setContentTitle("Test")
.setContentText("Test");
Intent resultIntent = new Intent(this, MainActivity.class);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());

That's not the purpose of setWhen. It's only a UI thing, if setShowWhen is enabled this timestamp is shown at the notification.
For your purpose, I would suggest the android AlarmManager. An example can be found here

setWhen() is used to show the time on the notification itself, not when the notification is shown.
The time on the top right of the notification is what setWhen() controls:
For showing the notification at a particular time, you can use the AlarmManager class. This has code to do the same.

How to disable multiple push Notification icon in Android, Am using Parse.com

com push notification for Android app, All is working well but lets say if i send 5 push notification a day, i dont want user to see 5 notification icons at once on his phone. Its best if he sees only one.So is their any way where old notification is deleted and only latest is shown.

mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
The method that displays the notification has an int parameter which represents the notification identifier. If you use a constant identifier, each new notification will replace the previous one.

you have to set the notification ID to be the same value. So then they get replaced as each one arrives.

int notificationId = 1 ;
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setAutoCancel(true);
builder.setSmallIcon(R.drawable.gcm_logo);
builder.setContentTitle("Test Title");
builder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(notificationId, builder.build());
So you can maintain notification Id for different type of notifications. If you keep same notification ID for each notification then it would be updated in the same .
If you have any extras in the pending intent and you want to update those extras with the latest ones then generate pending intent with :
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(),
PendingIntent.FLAG_ONE_SHOT);

Pushnotification not removed from notificationbar in android

In my application i received push notification from gcm, if i click on that push notification, my application will open and i need to remove my notification from notification bar. But , it is still on notification bar.
I used the following logic for generating push notification in my GCMIntentService class.
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
//PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, TipsActivity.class), 0);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, TipsActivity.class),
Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.icon)
.setContentTitle("Appname")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(msg))
.setContentText(msg);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
So, please guide me how to remove my notification , when i click on it.

Hi You have to add the following line>..
mBuilder.setAutoCancel(true);
Try this and let me know the feedback.

as per my guessing it is happening due to flag of notification
may be there is line in your code related to notification flag
may be that flag is FLAG_NO_CLEAR so change that flag to FLAG_AUTO_CANCEL
you will find this flag in generateNotification logic if you not mentioned the flag then please specify it as FLAG_AUTO_CANCEL
FLAG_NO_CLEAR means
Bit to be bitwise-ored into the flags field that should be set if the notification should not be canceled when the user clicks the Clear all button
and
FLAG_AUTO_CANCEL means
Bit to be bitwise-ored into the flags field that should be set if the notification should be canceled when it is clicked by the user.
here is the sample line
notification.flags |= Notification.FLAG_AUTO_CANCEL;
where notification is object of NotificationManager

hope it will resolve your issue happy coding

What is the difference between Notification and NotificationManger in Android?

What is the difference between those two?
I want to use the startForeground method and cannot use it with NotificationManager..
Thanks

A Notification is a class that represents either a persistent icon that goes in the status bar and is accessible through the launcher, turning on or flashing LEDs on the device, or alerting the user by flashing the backlight, playing a sound, or vibrating.
The Notification Manager is the class that allows you to add notifications to the system,
startForeground is a method of the Serivce class. For example inside your Service class you can have something like this.
Intent notificationIntent = new Intent(this, ActivityMain.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentIntent(pendingIntent)
.setSmallIcon(R.drawable.ic_stat_play)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher))
.setTicker(getString(R.string.app_name))
.setWhen(System.currentTimeMillis())
.setOngoing(true)
.setContentTitle(getString(R.string.app_name))
.setContentText(someText);
Notification notification = builder.build();
startForeground(1, notification);

A Notification is a description of what you want to occur to alert the user about something -- what icon goes in the status bar, what ringtone to play, etc.
NotificationManager is a system service that can show a Notification.
I want to use the startForeground methode and cannot use it with NotificationManager
Correct. Create a Notification using Notification.Builder (or NotificationCompat.Builder). See this project for an example of using startForeground().
