I used to show a number in app icon using this library as follows:
ShortcutBadger.applyCount(context, numberToShow);
OneSignal also has same function in its Android SDK.
Now in Oreo, with the introduction of notification channels, things get complex to me. I can create a channel. Then, I can also create a notification as follows:
public static void createNotification(Context context, int numberToShow) {
Notification notification = new NotificationCompat.Builder(context, context.getString(R.string.notification_channel_id))
.setContentTitle("Dummy Title")
.setContentText("Dummy content")
.setSmallIcon(R.drawable.app_icon)
.setNumber(numberToShow)
.build();
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
notificationManager.notify(0, notification);
}
However, I have to show a notification with this solution, which I don't need and thus don't want. Is there any way in Oreo that I can achieve the same thing I have done previously, i.e. just showing 'notification dot' or a number attached to the app icon?
Sorry, but there is no SDK-level support for showing numbers or other badges on launcher icons, other than the Notification scenario that you described.
set the importance of the notification channel to
IMPORTANCE_MIN
like int importance = NotificationManager.IMPORTANCE_MIN;
and then create the channel as -
NotificationChannel nChannel = new NotificationChannel
(channelId, title, importance);
This will the set the badge count(shown on the long press of the icon) without notifying the user about any notification in the system tray. Though the notification will be in the tray, but will not pop up and quietly reside there.
In earlier versions of Android, it was possible to have a notification that did not show an icon in the status bar, but was expanded by default by using the priority setting.
// Hide status bar icon AND show notification as expanded
builder.setPriority(NotificationCompat.PRIORITY_MIN);
However, now when targeting Android 25 (Oreo) on a device running Android 26, it seems this isn't possible. When I set the importance level to IMPORTANCE_MIN I achieve the desired effect of not showing an icon in the status bar. However, the notification is "collapsed" by default.
// Hide status bar icon (but notification is collapsed)
NotificationChannel(CHANNEL_ID, name, NotificationManager.IMPORTANCE_MIN);
If I set the importance level to (or above) IMPORTANCE_LOW then the notification is expanded by default, but shows an icon in the status bar.
// Expand notification (but shows status bar icon)
NotificationChannel(CHANNEL_ID, name, NotificationManager.IMPORTANCE_LOW);
Is there any way to force the notification to be expanded by default when using IMPORTANCE_MIN? Perhaps I've missed some setting.
PS: Please do not suggest using setSmallIcon to transparent. That's just an old ugly hack that looks awful.
By "collapsed" and "expanded" I mean this:
Collapsed:
Expanded:

I know this question is asked so many time related to Push notification status bar icon, but my problem is a little bit different.
I am using FCM push notification, my notification is coming properly. I have set notification icon for pre-lollipop and more then lollipop version. My notification icon is showing properly in dark theme devices like MOTO-G 5+, but when I check the same notification on light theme device like Samsung Galaxy Edge 7.0, my notification icon turns white as per app theme, but in another app, the notification icon is looking properly. I saw many example solution, but they did not help with my problem.
I am using following code :
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ila_app_icon);
long when = System.currentTimeMillis();
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setContentText(message)
.setContentIntent(pendingIntent)
// .setColor(getNotificationColor())
.setSmallIcon(getNotificationIcon(notificationBuilder))
.setWhen(when)
.setSound(defaultSoundUri)
.setLargeIcon(bitmap);
Random random = new Random();
int uniqueIntegerNumber = random.nextInt(9999 - 1000) + 1000;
notificationManager.notify(uniqueIntegerNumber, notificationBuilder.build());
Get notification icon method :-
private int getNotificationIcon(NotificationCompat.Builder notificationBuilder) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
int color = 0x008000;
notificationBuilder.setColor(color);
return R.drawable.notification_white;
}
return R.drawable.ila_app_icon;
}
I also tried setColor property, but that also doesn't work.
1) Light Theme ( Here the white flag icon )
Here is the screen shot :-
2) Dark Theme :-
After all searching and other things i found my solution,everything was working well expect the notification icon, the icon was keeping little bit pixel of different color.
We can create the notification icon from the following link, it makes our icon transparent for notification
https://romannurik.github.io/AndroidAssetStudio/icons-notification.html#source.type=clipart&source.clipart=ac_unit&source.space.trim=1&source.space.pad=0&name=ic_stat_ac_unit
Today I started targeting API 26 which forced me to use Notification Channels.
My problem is that now on each new notification (including updates to it) an annoying sound is played.
How can I disable this sound?
I tried replacing this sound with a custom mp3 sound in order to then pass it a mp3 with silence in it, but this is ignored.
I'm just adding a notification which is of very low priority, basically giving the user the option to perform some actions after he has interacted with the app. There's no reason to be loud, the user will know that he can refer to the notification because he has done a certain thing with the app which he knows that will cause a notification to appear.
The user will really start getting annoyed by that sound.
If you want to keep the importance of your channel and just remove the sound notificationChannel.setSound(null, null); seems to do the job.
EDIT:
Make sure to change the channel ID (and delete the old one) to have it applied to existing users. (Channels can be created, but never modified by the app, only the user can.)
(Update 2019-05: It gets worse with Android Q, there I'm even getting a sound when using NotificationManager.IMPORTANCE_LOW, at least in the Emulator...)
The solution is to use NotificationManager.IMPORTANCE_LOW and create a new channel for it. Once a channel is created, you can't change the importance (well, you can, but the new importance is ignored). The channel information appears to get stored permanently by the system and any channel created is only deleted when you uninstall the app. [Update: According to Ferran Negre's comment, you can delete the channel via nm.deleteNotificationChannel(nChannel.getId()); and recreate it with nm.createNotificationChannel(nChannel); but apparently there's a limitation that you can't create a channel with the same id of a deleted channel and expect to be able to apply different settings to the undeleted channel, see acoder's answer]
While previous Android versions played no sound back by default, this changed with Android O, but only when you target the API 26, that is, use Notification Channels. This is an inconsistency, well, actually, it's a bug:
The reason for this is that when you create a channel with NotificationManager.IMPORTANCE_DEFAULT (not soundworthy by default) Android will actually "somewhat" register it as NotificationManager.IMPORTANCE_HIGH (plays sound by default).
You can check this by going into the options of the notifications (long press on the notification entry), where you will get to read that it is of type NotificationManager.IMPORTANCE_HIGH and then disable the notification and then re-enable it. In this process it gets "downgraded" from the NotificationManager.IMPORTANCE_HIGH to the non-sounding, actually registered NotificationManager.IMPORTANCE_DEFAULT.
The bug has been submitted to the Android issue tracker, so you may want to star it (flagged by Google as "Won't Fix (Infeasible)", because... spoiled).
BTW, the new docs at https://developer.android.com/training/notify-user/channels
claim that the default behavior used to be that way, that default played a sound prior to Android 8.0, which is definitely not true. This is their list
User-visible importance level Importance Priority
(Android 8.0 and higher) (Android 7.1 and lower)
Urgent Makes a sound and appears as IMPORTANCE_HIGH PRIORITY_HIGH
a heads-up notification or PRIORITY_MAX
High Makes a sound IMPORTANCE_DEFAULT PRIORITY_DEFAULT
Medium No sound IMPORTANCE_LOW PRIORITY_LOW
Low No sound and does not appear IMPORTANCE_MIN PRIORITY_MIN
in the status bar
You can even see the mismatch between visibility importance high and notification importance high... I don't know why they are doing this. They definitely have a bug in their code.
Everything below the next line is obsolete, yet that bug mentioned there is still valid. My error there was to think that NotificationManager.IMPORTANCE_MIN is the next lower one from NotificationManager.IMPORTANCE_DEFAULT, but NotificationManager.IMPORTANCE_LOW is.
When you then go into the notification settings of the app via long-press-notification and all-channels button and toggle the switch for that channel off and on again, then it actually sets itself to NotificationManager.IMPORTANCE_DEFAULT and no sound will get played. I also noticed that after a crash it did get reset to NotificationManager.IMPORTANCE_HIGH
So basically the workaround is to use NotificationManager.IMPORTANCE_MIN. But you have to create a new channel so that this NotificationManager.IMPORTANCE_MIN is in effect, because it appears that you can't change the importance of an already existing channel once you have created it.
Update: Turns out the workaround with NotificationManager.IMPORTANCE_MIN has a drawback.
When you use that importance level then your notification no longer displays fully inside the notification drawer, but inserts itself in a new Notification Channel Group which is collapsed by default (and will collapse itself again each time the drawer is pulled down). What a bummer!
Update 2: Digging a bit deeper it turns out that it is as if it correctly registered it as NotificationManager.IMPORTANCE_DEFAULT, but somehow it magically got upgraded to NotificationManager.IMPORTANCE_HIGH, like it would when the user explicitly changes the setting from default to high. That one also gets reset to default after turning the notification off and then on again.
Well i will add a complete answer to help. If you read NotificationCompat code from androidx.
/**
* Silences this instance of the notification, regardless of the sounds or vibrations set
* on the notification or notification channel.
*/
public #NonNull Builder setNotificationSilent() {
mSilent = true;
return this;
}
So you have to use like this if you want remove sound AND vibration.
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID)
// no sound or vibration
.setNotificationSilent()
If you want remove sound only. This is the way.
// no sound
builder.setSound(null);
If you want remove viration only.
// no vibration
mChannel.setVibrationPattern(new long[]{ 0 });
mChannel.enableVibration(true);
NotificationCompat.Builder.setSilent(true)
This allows you to post a silent notification (no sound or vibration) regardless of the channel's importance setting.
Reference:
https://developer.android.com/reference/androidx/core/app/NotificationCompat.Builder#setSilent(boolean)
As far as I have seen, since API 26 (Oreo) it is not possible to change the sound of a notification after it was once created.
notificationManager.deleteNotificationChannel("channel_id"));
NotificationChannel notificationChannel = new NotificationChannel(
"channel_id", "channel_name",
NotificationManager.IMPORTANCE_HIGH);
notificationChannel.setSound(null, null);
notificationManager.createNotificationChannel(notificationChannel);
Even deleting the channel before creation does not help.
Google documentation says:
android.app.NotificationManager public void deleteNotificationChannel(String channelId)
Deletes the given notification channel.
If you create a new channel with this same id, the deleted channel will be un-deleted with all of the same settings it had before it was deleted.
NotificationChannel#setSound() documentation states
Only modifiable before the channel is submitted to NotificationManager#createNotificationChannel(NotificationChannel)
Too bad that notificationBuilder.setSound(defaultSoundUri) does not work as well:
This method was deprecated in API level 26. Use NotificationChannel#setSound(Uri, AudioAttributes) instead.
Also using support library does not work. So sound is only settable once in the app and changing by the user is only possible in the settings of the notification. For me Ferran Negre's comment did not work. I do not understand why Google made this restriction. Too bad.
I have tested a lot of android devices,the following code works for me properly
Firstly, create a notificationBuilder, if your Build.Version is bigger than 26, please add a new channel.
private val notificationBuilder: NotificationCompat.Builder by lazy {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) NotificationCompat.Builder(context) else {
val manager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val channelId = "MUSIC"
val channelName = "音乐控制栏"
val importance = NotificationManager.IMPORTANCE_MIN
val channel = NotificationChannel(channelId, channelName, importance)
manager.createNotificationChannel(channel)
channel.enableLights(false)
channel.vibrationPattern = longArrayOf(0L)
channel.enableVibration(false)
channel.setSound(null, null)
NotificationCompat.Builder(context, channelId)
}
}
Secondly, init this notificationBuilder, and set sound null
notificationBuilder.setDefaults(Notification.DEFAULT_LIGHTS ).setVibrate( longArrayOf(0L)).setSound(null)
Thirdly,if build.version is bigger than 24, please set its priority.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
notificationBuilder.priority = NotificationManager.IMPORTANCE_MIN
}
Hope that works for you.
NotificationManager.IMPORTANCE_LOW
It produces no sound when notification is created as I need the same in my Music Application.
And yes if you have already created a notification channel then either you need to change the channel id or simply uninstall the previous application and install again.
For me the solution was to create group notification.
val builder = NotificationCompat.Builder(this)
.setGroupAlertBehavior(GROUP_ALERT_SUMMARY)
.setGroup("My Group")
.setGroupSummary(false)
.setDefaults(DEFAULT_ALL)
.setSound(null)
But in this case, if you send a new notification with a new ID, then it will be grouped with the previous notifications.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val notificationChannel = NotificationChannel(
channelId.toString(), title,
NotificationManager.IMPORTANCE_DEFAULT
)
notificationChannel.setSound(null,null)
notificationChannel.enableVibration(false)
notificationChannel.description = body
if(notificationManager.getNotificationChannel(channelId.toString())==null) {
notificationManager.createNotificationChannel(notificationChannel)
}
if (data["sound"]?.equals("default", true) == true) {//if your app need contorl sound enable
RingtoneManager.getRingtone(
this,
RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
).play()
}
if(pushShake.isTrue() ){//if your app need contorl vibarate enable
val vbmanager= getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
vbmanager.vibrate(VibrationEffect.createOneShot(500,VibrationEffect.DEFAULT_AMPLITUDE))
}
}
below code is about notification, but sound,vibrate will not play at API 26 ,so dont worry about setsound or setvibrate
notificationManager.notify(channelId.toInt(), notificationBuilder.apply {
setContentIntent(pendingIntent)
setSmallIcon(R.drawable.img_logo)
setTicker(title)
setNumber(data["badge"]?.toIntOrNull() ?: 0)
setBadgeIconType(NotificationCompat.BADGE_ICON_SMALL)
color = if (Build.VERSION.SDK_INT > Build.VERSION_CODES.M) {
resources.getColorMuteDepre(R.color.colorAccent2)
} else {
Color.parseColor("#ffffff")
}
setContentTitle(title)
setContentText(body)
setWhen(System.currentTimeMillis())
setAutoCancel(true)
setSound(null)
setVibrate(longArrayOf())
if (pushShake.isTrue() && data["sound"]?.equals("default", true) == true) {
setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
val vbmanager = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
vbmanager.vibrate(500)
}
}else{
if (data["sound"]?.equals("default", true) == true) {
setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
}
if (pushShake.isTrue() ) {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
val vbmanager = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
vbmanager.vibrate(500)
}
}
}
setStyle(
NotificationCompat.BigTextStyle().bigText(body).setSummaryText(body).setBigContentTitle(
title
)
)
setPriority(NotificationCompat.PRIORITY_DEFAULT)
}.build())
As IMPORTANCE solution has the side effect of no notification popup, I got a final solution is:
adding a silent sound resource which downloaded from below repo
set sound for the channel with the silent sound resource.
https://github.com/anars/blank-audio/blob/master/1-second-of-silence.mp3
If the case is like mine, that I am forced to show a notification for background service and I don't really want to show any notification the solution that worked on 8.0 was:
.setPriority(NotificationManager.IMPORTANCE_NONE)
With this not only I didn't get the annoying sound every 5 minutes but also minimized the appearance of the notification itself.
On 8.1 I didn't have the problem with the sound with following:
.setPriority(NotificationManager.IMPORTANCE_MIN)
You can use 2 different notification channel to send notification depending on there priority to user.
If its a high priority notification the send it via
new NotificationChannel("Channel ID", "Channel Name", NotificationManager.IMPORTANCE_HIGH);
Your user will get sound and pop when they will receive a notification.
If you want to send less important notification then use this channel.
new NotificationChannel("Channel ID", "Channel Name", NotificationManager.IMPORTANCE_LOW);
Your user will get a notification with no sound and pop up.
check different priority from here - https://developer.android.com/reference/android/app/NotificationManager
No need to use .setSound(null, null)
just use below code
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this,
getString(R.string.notification_channel_id))
.setContentTitle("Audio Recording")
.setContentText("recording in progress")
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
.setSmallIcon(R.mipmap.ic_launcher);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(
getString(R.string.notification_channel_id), "AOD+", NotificationManager.IMPORTANCE_LOW
);
channel.setDescription("Call Recorder is running");
channel.setShowBadge(true);
channel.canShowBadge();
channel.setLightColor(Color.GREEN);
channel.enableVibration(false);
assert notificationManager != null;
notificationManager.createNotificationChannel(channel);
}
assert notificationManager != null;
startForeground(256/* must be greater than 0*/, notificationBuilder.build()); //I am using this for audio recording
//notificationManager.notify(0, notificationBuilder.build());
First you need to set
importance = NotificationManager.IMPORTANCE_LOW;
then
Notification n = builder.setPriority(Notification.DEFAULT_ALL).build();
n.defaults = 0;
n.defaults |= Notification.DEFAULT_VIBRATE;
NotificationManager.IMPORTANCE_LOW
This will work but also collapsed your notification.
NotificationManager.IMPORTANCE_LOW will work for sure
I faced the same issue in the 8.1 and made the below changes. Change the priority of the notification as LOW and it will disable the sound of notification.
NotificationManager.IMPORTANCE_LOW
The code is like following:
NotificationChannel chan1 = new NotificationChannel("default", "default", NotificationManager.IMPORTANCE_LOW);
I am using FCM push notification for my app, everything is working fine. but right now, I am getting a small icon below my notification icon. See below image.
Can any one tell me what is the size we can use for this icon? And how can we customize it?How can i add icon or image at that place?
You can use badge icon of any size like 72x72 or any
but the thing is your icon should be .png extension only of transparent background and icon color should be white only... Here is the code for setting large notification icon and badge icon
String title = context.getString(R.string.app_name);
Bitmap bm = BitmapFactory.decodeResource(context.getResources(), R.drawable.logo);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.tlogo)
.setLargeIcon(bm)
.setContentTitle(title)
.setContentText(message)
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
.setWhen(when);
The icon in the image suggests that the notification has come from Chrome which recently added support for badge customisation in version 53.
There is sadly no guidance on the recommended size, but a square image with transparent background and only white would be the recommendation I can give.
72x72px is probably a good bet for image size based on Android docs which suggest a badge size of 24dips (which can be thought of as 24px multiplied by a devices screen density). So 24px x 3 = 72px.
To set the badge on a web notification you need to include a badge options:
self.addEventListener('push', function(event) {
event.waitUntil(
self.registration.showNotification(
'Hello', {
body: 'Thanks for sending this push msg.',
icon: './images/icon-192x192.png',
badge: './images/icon-72x72.png'
})
);
});

I tried this and it solved,sorry for late answer
private void sendNotification(String messageBody,String titles) {
Intent intent = new Intent(this, NotificationList.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);
Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.mipmap.appicon);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setContentTitle(titles)
.setLargeIcon(largeIcon)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setSmallIcon(getNotificationIcon())
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
private int getNotificationIcon() {
boolean useWhiteIcon = (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M);
return useWhiteIcon ? R.mipmap.notismall : R.mipmap.appicon;
}
The icon size is not stated in the Firebase reference documentation for the notification payload used to send messages to client apps, however you can check out the guidelines in creating icons for Android and IOS.
So I did some digging about Android Notifications and Building Notifications. You can set the icon by using the icon parameter.
However, for the Badge inside the notification, this one seems to be handled by the Android System itself and cannot be modified. Depending also on the device, it may very well be that the badge is not visible, since Android itself doesn't allow Notification Badges even for App Icons.
So far, I've done some testing on my device and only the notifications that show badges are the ones that can be opened by Google Apps (Gmail, Drive, Photos, etc.) and the notifications sent by Device Manufacturer.
The one you've included in your post must be a default badge made by the device manufacturer and it is only showing because of the Device's App Launcher.
So long story short, it's not possible for you to set the Notification's Icon Badge.
if you want to hide the small icon on top of large icon use
int smallIconId = mContext.getResources().getIdentifier("right_icon", "id", android.R.class.getPackage().getName());
Notification notification = notificationBuilder.build();
if (smallIconId != 0) {
notification.contentView.setViewVisibility(smallIconId, View.INVISIBLE);
}
you can even play more with findviewById(smallIconId)
