I am trying to post a notification to the status bar without any intent, but nothing is happening?
Am I missing anything? This code is inside my push notification receiver service.
notificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentTitle("Hello");
builder.setContentTitle("This is my message");
builder.setSmallIcon(R.drawable.ic_launcher);
PendingIntent intent = PendingIntent.getActivity(this, 0, new Intent(), PendingIntent.FLAG_UPDATE_CURRENT);
builder.setFullScreenIntent(intent, true);
notificationManager.notify(555, builder.build());
As mentioned in my comment, to create a notification for the notification manager, a small icon must also be provided.
Additionally, for developers targeting Android 2.2 and 2.3 as well, make sure to include a content Intent otherwise the app will crash.

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());

Notification Icon with the new Firebase Cloud Messaging system
(10 answers)
Closed 6 years ago.
I'm using Firebase Notification for my app's push notifications.
All working well but notification icon shows white circle when app is not running.
I'm targeting SDK version 23, also I'm using Roman Nurik's notification icon generator to generate white-on-transparent icons.
Notification icon is showing correctly when app is on foreground and running. img
But icon gets replaced with generic white circle when app is in background or killed. img
Here's my notification builder method:
private void sendNotification(String messageTitle, String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder notification = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_stat_notification_icon)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setStyle(new NotificationCompat.BigTextStyle().bigText(messageBody))
.setAutoCancel(true)
.setPriority(Notification.PRIORITY_DEFAULT)
.setDefaults(Notification.DEFAULT_ALL)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notification.build());
}
I've already found an answer on similar issue: Notification Icon with the new Firebase Cloud Messaging system
Unfortunately this is a limitation of Firebase Notifications in SDK
9.0.0. When the app is in the background the launcher icon is use from the manifest (with the requisite Android tinting) for messages sent
from the console.
If the app is in the foreground (or a data message is sent) you should
be able to use your own logic to customise, and you should be able to
customise the icon if sending the message from the HTTP/XMPP APIs.
Right now with messages sent from the console you'll get this
behavior.
It seems to be that the best way to avoid this Firebase Notifications bug is to change your targetSdkVersion in build.gradle to 19. The notification icon will be then colored. Firebase after a while will fix this issue.
Hope it will help
try this code:
Intent intent = new Intent(this, TabActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(getNotificationIcon())
.setContentTitle("IDS DMS Support")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
I think that you need to add a silhouette icon to the app and use it if the device is running Android Lollipop.
Use below code to get small icon for notification.
protected int getNotificationIcon() {
boolean useWhiteIcon = (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP);
return useWhiteIcon ? R.drawable.ic_silhouette : R.drawable.ic_launcher;
}

I did same thing and works fine.
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);
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().
I've been developing for Android for awhile but this is my first shot at notifications. I've got my notification setup as described in the Android SDK tutorial, but I can't figure out how to keep the notification displayed until my app is closed. I want to disable that little minus sign at the end of the notification. I don't want my notification to disappear when a user clicks it. I would think there would be a notification flag... but I can't seem to figure this out. I'm developing on Android SDK 2.2. I know this is a simple question, and I apologize if this answer is already on here... I wasn't able to find exactly what I was looking for.
// Create notification manager
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
Notification notification = new Notification(R.drawable.ic_launcher, "Ready", System.currentTimeMillis());
Intent notificationIntent = new Intent(this, HomeActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
// Make a notification
notification.setLatestEventInfo(getApplicationContext(), "Ready", "Select to manage your settings", contentIntent);
mNotificationManager.notify(0, notification);
You want FLAG_ONGOING_EVENT. Also try removing FLAG_NO_CLEAR and FLAG_AUTO_CANCEL if they are part of the defaults.
