In my application iam showing a ongoing notification while doing a video upload. I want to clear the notification after upload. I searched a lot and cant get a clear answer.Please help me if anybody knows...
From Managing your Notifications in android documentation:
You can also clear it manually with cancel(int), passing it the
notification ID, or clear all your notifications with cancelAll().
So you should perform following to hide the notification:
mNotificationManager.cancel(notification_id);
where mNotificationManager is NotificationManager object and notification_id is int identifier of notification passed to NotificationManager object:
mNotificationManager.notify(notification_id, notification);
Just to show how this is done with Notification.Builder you can set the FLAG_AUTO_CANCEL like this:
Notification.Builder mBuilder = new Notification.Builder(getContext())
.setSmallIcon(R.drawable.icon)
.setContentTitle("My notification")
.setContentText("Hello Notify!")
.setOngoing(true)
.setAutoCancel(true);
You can clear your notification by clicking on it..!!
Notification notification = new Notification("Your needed data..");
notification.flags |= Notification.FLAG_AUTO_CANCEL;

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());
I have a very strange issue, I am working on Push Notification and it was successfully implemented but when i have used BigTextStyle in Notification to show a long message in notification area with setFullScreenIntent() method then the issue coming up the Notification opening the Activity automatically which is set in PendingIntent.
If I don't use setFullScreenIntent() then notification won't opening Activity automatically the user has to tap or click on Notification to open the Activity set in PendingIntent.
So there are two codes
Without setFullScreenIntent() working fine and not opening Activity automatically:
notification = new NotificationCompat.Builder(context)
.setContentTitle("Title")
.setContentIntent(resultPendingIntent)
.setContentText(message)
.setStyle(
new NotificationCompat.BigTextStyle()
.bigText(message))
.setSmallIcon(R.drawable.ic_launcher)
.setAutoCancel(true);
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(1, notification.build());
With setFullScreenIntent() also working fine but opening Activity automatically:-
notification = new NotificationCompat.Builder(context)
.setContentTitle("Title")
.setContentIntent(resultPendingIntent)
.setContentText(message)
.setStyle(
new NotificationCompat.BigTextStyle()
.bigText(message))
.setSmallIcon(R.drawable.ic_launcher)
.setFullScreenIntent(resultPendingIntent, true) //Whether true or false same result
.setAutoCancel(true);
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(1, notification.build());
public NotificationCompat.Builder setFullScreenIntent (PendingIntent intent, boolean highPriority)
An intent to launch instead of posting the notification to the status
bar. Only for use with extremely high-priority notifications demanding
the user's immediate attention, such as an incoming phone call or
alarm clock that the user has explicitly set to a particular time. If
this facility is used for something else, please give the user an
option to turn it off and use a normal notification, as this can be
extremely disruptive.
On some platforms, the system UI may choose to display a heads-up
notification, instead of launching this intent, while the user is
using the device.
Parameters
intent: The pending intent to launch.
highPriority: Passing
true will cause this notification to be sent even if other
notifications are suppressed.
Found here. As you can see it immediately launches the intent. I don't really know in what case you wanted to use setFullScreenIntent()?
A notification won't automatically expand when a static notification is displayed on top (could be custom bar with wifi, bluetooth and sound control)
pass setFullScreenIntent and setContentIntent with different pending intents.
Worked for me. click on Notif will work and autolaunch will stop
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
I am new to android. I want to now how to create a notification in the notification bar and compose it like 'usb connected' or 'usb debugging connected' notify. Can anyone help me with some codes?
I have used NotificationCompat.Builder for the purpose
First we have to style the notification
NotificationCompat.Builder mBuilder=new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher) // icon to be displayed
.setContentTitle("Notification") // title for the notification
.setContentText(msg); // msg is some text you want to display
For Led light blinkering when notification is received
mBuilder.setLights(Color.BLUE,1000,1200);
To give notification sound you can make use of default notification sound set by the user
Uri sound=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
mBuilder.setSound(sound);
To cancel the notification when the user has selected it
mBuilder.setAutoCancel(true);
To start an activity in app when the user clicks the notification
Intent resultIntent = new Intent(this,ExampleActivity.class);
PendingIntent resultPendingIntent =PendingIntent.getActivity(this,0, resultIntent,0);
mBuilder.setContentIntent(resultPendingIntent);
Finally to show the notification in the bar make use of notification manager
NotificationManager mNotificationManager =
(NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
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.
How can i now show it in status/notification bar along with the sound?
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);
