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:

NotificationManager notifManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, NotificationManager.IMPORTANCE_LOW);
notifManager.createNotificationChannel(channel);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, CHANNEL_ID);
builder.setContent(myRemoteViews);
builder.setSmallIcon(R.drawable.status);
builder.setOngoing(true);
builder.setTicker(tickerText);

Notification notif = builder.build();
notifManager.notify(NOTIF_ID, notif);

I have an issue with hiding the notification icon in the status bar from a service notification.
Here what I did:
I set the notification priority to min, make them silents
NotificationCompat.Builder builder = new NotificationCompat.Builder(this,"test");
builder.setSmallIcon(R.drawable.notif);
builder.setContentTitle(getString(R.string.app_name));
builder.setContentText(profile.mName);
builder.setContentIntent(pendingIntent);
builder.setNotificationSilent();
builder.setPriority(NotificationCompat.PRIORITY_MIN);
In the channel, I set the priority to min too but I still see the notification icon in the status bar
NotificationChannel channel = new NotificationChannel(id, getApplicationContext().getString(R.string.app_name), NotificationManager.IMPORTANCE_MIN);
channel.setSound(null, null);
channel.setImportance(NotificationManager.IMPORTANCE_MIN);
channel.enableVibration(false);
Alright, the thing I can understand that you first tried with priority or importance high with notification channel. According to documentation once notification channel created then it cannot be updated by changing code. If you want to apply new changes like priority or importance low like you did in code, then you need to clear app cache or uninstall app and then re-install again.This will apply new notification channel changes to your app.
I'm using android studio and want to match everything with my project colors.
How can I set the color of the icons in the notificationbar? Or if not possible hide only the icons, not the bar?
Thanks in advance
When building the notification, you can set the color and the icon. (If your icon is a pure white image, it'll apply the color for you in the correct spots.)
here is my code I have used recently
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val manager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val notificationId = 10 // Some unique id.
// Creating a channel - required for O's notifications.
val channel = NotificationChannel("my_channel_01",
"Channel human-readable title",
NotificationManager.IMPORTANCE_DEFAULT)
manager.createNotificationChannel(channel)
// Building the notification.
val builder = Notification.Builder(context, channel.id)
builder.setContentTitle("Warning!")
builder.setContentText("This is a bad notification!")
builder.setSmallIcon(R.drawable.skull)
builder.setColor(ContextCompat.getColor(context, R.color.colorPrimary))
builder.setChannelId(channel.id)
// Posting the notification.
manager.notify(notificationId, builder.build())
}
here in the first-line check the verion of your phone and according to that will get notification Style
builder. small icon and builder.set color(Give color you desire)
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.
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)
public void animatedNotification() {
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(ic)
.setLights(Color.GREEN, 10000, 10000)
.setWhen(when)
.setPriority(Notification.PRIORITY_HIGH)
.setContentTitle(title)
.setContentText("Plants Need Watering Some of Your work is pending");
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(0, mBuilder.build());
}
.setSmallIcon(android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP ? R.mipmap.ic_launcher : R.drawable.notification_icon_bw_xhdpi)
.setColor(ResourcesCompat.getColor(getResources(), R.color.primary, getTheme()))
Use color to distinguish your app from others. Notification icons should only be a white-on-transparent background image. (https://developer.android.com/design/patterns/notifications.html)
Before Android Lollipop you can use same mipmap icon for all notification icon. But from Lollipop onwards you need to create new notification icon (Silhoette kind of icon).
Small icon appears white because of Material theme used for your app notification.
