Yesterday Google presented at Google I/O the new notification system based on the new Firebase. I tried this new FCM ( Firebase Cloud Messaging ) with the example on Github.
The icon of the notification is always the ic_launcher despite I have declared a specific drawable
Why ?
Here below the official code for handling the message
public class AppFirebaseMessagingService extends FirebaseMessagingService {
/**
* Called when message is received.
*
* #param remoteMessage Object representing the message received from Firebase Cloud Messaging.
*/
// [START receive_message]
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
sendNotification(remoteMessage);
}
// [END receive_message]
/**
* Create and show a simple notification containing the received FCM message.
*
* #param remoteMessage FCM RemoteMessage received.
*/
private void sendNotification(RemoteMessage remoteMessage) {
Intent intent = new Intent(this, MainActivity.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);
// this is a my insertion looking for a solution
int icon = Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ? R.drawable.myicon: R.mipmap.myicon;
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(icon)
.setContentTitle(remoteMessage.getFrom())
.setContentText(remoteMessage.getNotification().getBody())
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
Unfortunately this was a limitation of Firebase Notifications in SDK 9.0.0-9.6.1. 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.
With SDK 9.8.0 however, you can override the default! In your AndroidManifest.xml you can set the following fields to customise the icon and color:
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/notification_icon" />
<meta-data android:name="com.google.firebase.messaging.default_notification_color"
android:resource="#color/google_blue" />
Note that if the app is in the foreground (or a data message is sent) you can completely use your own logic to customise the display. You can also always customise the icon if sending the message from the HTTP/XMPP APIs.
Use a server implementation to send messages to your client and use data type of messages rather than notification type of messages.
This will help you get a callback to onMessageReceived irrespective if your app is in background or foreground and you can generate your custom notification then
atm they are working on that issue https://github.com/firebase/quickstart-android/issues/4
when you send a notification from the Firebase console is uses your app icon by default, and the Android system will turn that icon solid white when in the notification bar.
If you are unhappy with that result you should implement FirebaseMessagingService and create the notifications manually when you receive a message. We are working on a way to improve this but for now that's the only way.
edit: with SDK 9.8.0 add to AndroidManifest.xml
<meta-data android:name="com.google.firebase.messaging.default_notification_icon" android:resource="#drawable/my_favorite_pic"/>
My solution is similar to ATom's one, but easier to implement. You don't need to create a class that shadows FirebaseMessagingService completely, you can just override the method that receives the Intent (which is public, at least in version 9.6.1) and take the information to be displayed from the extras. The "hacky" part is that the method name is indeed obfuscated and is gonna change every time you update the Firebase sdk to a new version, but you can look it up quickly by inspecting FirebaseMessagingService with Android Studio and looking for a public method that takes an Intent as the only parameter. In version 9.6.1 it's called zzm.
Here's how my service looks like:
public class MyNotificationService extends FirebaseMessagingService {
public void onMessageReceived(RemoteMessage remoteMessage) {
// do nothing
}
#Override
public void zzm(Intent intent) {
Intent launchIntent = new Intent(this, SplashScreenActivity.class);
launchIntent.setAction(Intent.ACTION_MAIN);
launchIntent.addCategory(Intent.CATEGORY_LAUNCHER);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* R equest code */, launchIntent,
PendingIntent.FLAG_ONE_SHOT);
Bitmap rawBitmap = BitmapFactory.decodeResource(getResources(),
R.mipmap.ic_launcher);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_notification)
.setLargeIcon(rawBitmap)
.setContentTitle(intent.getStringExtra("gcm.notification.title"))
.setContentText(intent.getStringExtra("gcm.notification.body"))
.setAutoCancel(true)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
if your app is in background the notification icon will be set onMessage Receive method but if you app is in foreground the notification icon will be the one you defined on manifest
Just set targetSdkVersion to 19. The notification icon will be colored.
Then wait for Firebase to fix this issue.
There is also one ugly but working way. Decompile FirebaseMessagingService.class and modify it's behavior. Then just put the class to the right package in yout app and dex use it instead of the class in the messaging lib itself. It is quite easy and working.
There is method:
private void zzo(Intent intent) {
Bundle bundle = intent.getExtras();
bundle.remove("android.support.content.wakelockid");
if (zza.zzac(bundle)) { // true if msg is notification sent from FirebaseConsole
if (!zza.zzdc((Context)this)) { // true if app is on foreground
zza.zzer((Context)this).zzas(bundle); // create notification
return;
}
// parse notification data to allow use it in onMessageReceived whe app is on foreground
if (FirebaseMessagingService.zzav(bundle)) {
zzb.zzo((Context)this, intent);
}
}
this.onMessageReceived(new RemoteMessage(bundle));
}
This code is from version 9.4.0, method will have different names in different version because of obfuscation.
write this
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/ic_notification" />
right down <application.....>
I'm triggering my notifications from FCM console and through HTTP/JSON ... with the same result.
I can handle the title, full message, but the icon is always a default white circle:
Notification screenshot
Instead of my custom icon in the code (setSmallIcon or setSmallIcon) or default icon from the app:
Intent intent = new Intent(this, MainActivity.class);
// use System.currentTimeMillis() to have a unique ID for the pending intent
PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);
if (Build.VERSION.SDK_INT < 16) {
Notification n = new Notification.Builder(this)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pIntent)
.setAutoCancel(true).getNotification();
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
//notificationManager.notify(0, n);
notificationManager.notify(id, n);
} else {
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
Notification n = new Notification.Builder(this)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setSmallIcon(R.drawable.ic_stat_ic_notification)
.setLargeIcon(bm)
.setContentIntent(pIntent)
.setAutoCancel(true).build();
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
//notificationManager.notify(0, n);
notificationManager.notify(id, n);
}
Thought I would add an answer to this one, since my problem was simple but hard to notice. In particular I had copy/pasted an existing meta-data element when creating my com.google.firebase.messaging.default_notification_icon, which used an android:value tag to specify its value. This will not work for the notification icon, and once I changed it to android:resource everything worked as expected.

Is it possible to clear a notification programatically?
I tried it with the NotificationManager but its not working.
Is there any other way I can do it?
Use the following code to cancel a Notification:
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(NOTIFICATION_ID);
In this code there is alway the same id used for notifications. If you have different notifications that need to be canceled you have to save the ids that you used to create the Notification.
From: http://developer.android.com/guide/topics/ui/notifiers/notifications.html
To clear the status bar notification when the user selects it from the Notifications window, add the "FLAG_AUTO_CANCEL" flag to your Notification object. You can also clear it manually with cancel(int), passing it the notification ID, or clear all your Notifications with cancelAll().
But Donal is right, you can only clear notifications that you created.
Since no one has posted a code answer to this:
notification.flags = Notification.FLAG_AUTO_CANCEL;
.. and if you already have flags, you can OR FLAG_AUTO_CANCEL like this:
notification.flags = Notification.FLAG_INSISTENT | Notification.FLAG_AUTO_CANCEL;
Please try methods provided in NotificationManagerCompat.
To remove all notifications,
NotificationManagerCompat.from(context).cancelAll();
To remove a particular notification,
NotificationManagerCompat.from(context).cancel(notificationId);
Starting with API level 18 (Jellybean MR2) you can cancel Notifications other than your own via NotificationListenerService.
#TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2)
public class MyNotificationListenerService extends NotificationListenerService {...}
...
private void clearNotificationExample(StatusBarNotification sbn) {
myNotificationListenerService.cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId());
}
If you are generating Notification from a Service that is started in the foreground using
startForeground(NOTIFICATION_ID, notificationBuilder.build());
Then issuing
notificationManager.cancel(NOTIFICATION_ID);
does not end up canceling the Notification, and the notification still appears in the status bar. In this particular case, you will need to issue
stopForeground( true );
from within the service to put it back into background mode and to simultaneously cancel the notifications. Alternately, you can push it into the background without having it cancel the notification and then cancel the notification.
stopForeground( false );
notificationManager.cancel(NOTIFICATION_ID);
Notification mNotification = new Notification.Builder(this)
.setContentTitle("A message from: " + fromUser)
.setContentText(msg)
.setAutoCancel(true)
.setSmallIcon(R.drawable.app_icon)
.setContentIntent(pIntent)
.build();
.setAutoCancel(true)
when you click on notification, open corresponding activity and remove notification from notification bar
I believe the most RECENT and UPDATED for AndroidX and backward compatibility. The best way of doing (Kotlin and Java) this should be done as:
NotificationManagerCompat.from(context).cancel(NOTIFICATION_ID)
Or to cancel all notifications is:
NotificationManagerCompat.from(context).cancelAll()
Made for AndroidX or Support Libraries.
If you're using NotificationCompat.Builder (a part of android.support.v4) then simply call its object's method setAutoCancel
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setAutoCancel(true);
Some guys were reporting that setAutoCancel() did not work for them, so you may try this way as well
builder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
Note that the method getNotification() has been deprecated!!!
// Get a notification builder that's compatible with platform versions
// >= 4
NotificationCompat.Builder builder = new NotificationCompat.Builder(
this);
builder.setSound(soundUri);
builder.setAutoCancel(true);
this works if you are using a notification builder...
Actually as answered before starting with API Level 18 you can cancel Notifications posted by other apps differet than your own using NotificationListenerService but that approach will no longer work on Lollipop, here is the way to remove notifications covering also Lillipop API.
if (Build.VERSION.SDK_INT < 21) {
cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId());
}
else {
cancelNotification(sbn.getKey());
}
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager Nmang = (NotificationManager) getApplicationContext()
.getSystemService(ns);
Nmang .cancel(getIntent().getExtras().getInt("notificationID"));
All notifications (even other app notifications) can be removed via listening to 'NotificationListenerService' as mentioned in NotificationListenerService Implementation
In the service you have to call cancelAllNotifications().
The service has to be enabled for your application via:
‘Apps & notifications’ -> ‘Special app access’ -> ‘Notifications access’.
this code worked for me:
public class ExampleReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
int notificationId = 1;
notificationManager.cancel(notificationId);
}
}
A function written in Kotlin:
/**
* Delete the notification
*/
fun delete(context: Context, notificationId: Int) =
with(NotificationManagerCompat.from(context)) {
cancel(notificationId)
}
Or shorter:
fun delete(context: Context, notificationId: Int) = NotificationManagerCompat.from(context).cancel(notificationId)
If you use OneSignal, you must use one of this:
Specific notification:
OneSignal.removeNotification(mutableNotification.androidNotificationId)
All notifications:
OneSignal.clearOneSignalNotifications()
In OneSignal's java doc says:
For removeNotification
Cancels a single OneSignal notification based on its Android notification integer ID. Use
* instead of Android's {#link NotificationManager#cancel(int)}, otherwise the notification will be restored
* when your app is restarted.
For clearOneSignalNotifications
If you just use
* {#link NotificationManager#cancelAll()}, OneSignal notifications will be restored when
* your app is restarted.
To clear notifications on Oreo and greater versions
//Create Notification
Notification.Builder builder = new Notification.Builder(this, NOTIFICATION_CHANNEL_ID)
.setContentTitle(getString(R.string.app_name))
.setAutoCancel(true);
Notification notification = builder.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
createNotificationChannel(builder, notificationManager);
mNotificationManager=notificationManager;
startForeground(1, notification);
//Remove notification
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
mNotificationManager.deleteNotificationChannel(NOTIFICATION_CHANNEL_ID);
}

I use fcm and heads up notification will show when app is open but not show when app is not open or killed.
How to handle heads up notification when app is not open?
Doc say :
With Android 5.0 (API level 21), notifications can appear in a small
floating window (also called a heads-up notification) when the device
is active (that is, the device is unlocked and its screen is on).
These notifications appear similar to the compact form of your
notification, except that the heads-up notification also shows action
buttons. Users can act on, or dismiss, a heads-up notification without
leaving the current app.
As per Doc, If you want heads-up notification you have to create your own as below :
notificationBuilder.setPriority(Notification.PRIORITY_HIGH);
if (Build.VERSION.SDK_INT >= 21) notificationBuilder.setVibrate(new long[0]);
Don't abuse heads-up notification. See here for when to use heads-up notification:
MAX: For critical and urgent notifications that alert the user to a
condition that is time-critical or needs to be resolved before they
can continue with a particular task.
HIGH: Primarily for important communication, such as messages or chat
events with content that is particularly interesting for the user.
High-priority notifications trigger the heads-up notification display.
Additional note from HERE
Update :
To override GCM listener service :
<service android:name=".MyGcmListenerService"
android:exported="false">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
FCM would be :
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
Then override method :
GCM :
public class MyGcmListenerService
extends GcmListenerService {
#Override
public void onMessageReceived(String from, Bundle data) {
... create your heads-up notification here.
}
FCM :
public class MyFirebaseMessagingService extends FirebaseMessagingService {
/**
* Called when message is received.
*
* #param remoteMessage Object representing the message received from Firebase Cloud Messaging.
*/
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
... create your heads-up notification here.
}
Can't post in comment, so here it is. Try this, i had tested :
private void test() {
Intent intent;
intent = new Intent(this, SplashScreenActivity.class);
Bundle bundle = new Bundle();
bundle.putBoolean("isDisplayAlert", true);
bundle.putString("NOTIFICATION_DATA", "data");
intent.putExtras(bundle);
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(),
new Random().nextInt(), intent,
PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_location)
.setContentTitle("Title")
.setContentText("Body")
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setOnlyAlertOnce(true)
.setFullScreenIntent(pendingIntent, true);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationBuilder.setPriority(Notification.PRIORITY_HIGH);
notificationBuilder.setVibrate(new long[0]);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
hey all i got a tough problem and need advice. I have constructed a notification manually after recieving a FCM data payload. This is how the notification gets created both in foreground and background since its a data payload:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
String msg = remoteMessage.getData().get("message");
sendNotification(msg);
}
private PendingIntent createIntent(String msg) {
Intent intent = new Intent(this, SportsActivity.class);
Bundle b = new Bundle();
b.putString(Constants.KEY_GO_TO_TAB, Constants.KEY_DASHBOARD_HOCKEY_SCORE_TAB);
intent.putExtras(b);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
return pendingIntent;
}
private void sendNotification( String messageBody) {
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
android.support.v4.app.NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(messageBody))
.setContentText(messageBody)
.setColor(ContextCompat.getColor(this, R.color.hockey_brand))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(createIntent(messageBody));
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}
it seems to function fine. The issue im having is i want the notification to NOT SHOW in when the app is in the foreground. is there not a way to do this without scanning the activity task ? as this requires a permission
i've read this article but this how to know you've went from foreground to background. also android.permission.GET_TASKS is deprecated and REAL_GET_TASKS permission is not for third party either. I simply want to know at any given time that the user is either in foreground or background so i know if i should show a notification or not. I wonder if firebase itself has something. When you send a "Notification payload" from the firebase console if the app is not in the foreground is does not show in the notification panel so there should be a way to do this.
Alternatively you can choose not to show your notification when your app is in foreground by implementing Application.ActivityLifecycleCallbacks
in your Application.
Then you can check if your app is in foreground or background.

Actually as answered before starting with API Level 18 you can cancel Notifications posted by other apps differet than your own using NotificationListenerService but that approach will no longer work on Lollipop, here is the way to remove notifications covering also Lillipop API.
if (Build.VERSION.SDK_INT < 21) {
cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId());
}
else {
cancelNotification(sbn.getKey());
}
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager Nmang = (NotificationManager) getApplicationContext()
.getSystemService(ns);
Nmang .cancel(getIntent().getExtras().getInt("notificationID"));
All notifications (even other app notifications) can be removed via listening to 'NotificationListenerService' as mentioned in NotificationListenerService Implementation
In the service you have to call cancelAllNotifications().
The service has to be enabled for your application via:
‘Apps & notifications’ -> ‘Special app access’ -> ‘Notifications access’.
this code worked for me:
public class ExampleReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
int notificationId = 1;
notificationManager.cancel(notificationId);
}
}
A function written in Kotlin:
/**
* Delete the notification
*/
fun delete(context: Context, notificationId: Int) =
with(NotificationManagerCompat.from(context)) {
cancel(notificationId)
}
Or shorter:
fun delete(context: Context, notificationId: Int) = NotificationManagerCompat.from(context).cancel(notificationId)
If you use OneSignal, you must use one of this:
Specific notification:
OneSignal.removeNotification(mutableNotification.androidNotificationId)
All notifications:
OneSignal.clearOneSignalNotifications()
In OneSignal's java doc says:
For removeNotification
Cancels a single OneSignal notification based on its Android notification integer ID. Use
* instead of Android's {#link NotificationManager#cancel(int)}, otherwise the notification will be restored
* when your app is restarted.
For clearOneSignalNotifications
If you just use
* {#link NotificationManager#cancelAll()}, OneSignal notifications will be restored when
* your app is restarted.
To clear notifications on Oreo and greater versions
//Create Notification
Notification.Builder builder = new Notification.Builder(this, NOTIFICATION_CHANNEL_ID)
.setContentTitle(getString(R.string.app_name))
.setAutoCancel(true);
Notification notification = builder.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
createNotificationChannel(builder, notificationManager);
mNotificationManager=notificationManager;
startForeground(1, notification);
//Remove notification
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
mNotificationManager.deleteNotificationChannel(NOTIFICATION_CHANNEL_ID);
}
