non removable notification - android

In my app, there is service running on background. I want to notify user that the service is running. But I need that user cannot delete the notification - by pressing clear button or by swipe it out, in notification bar
It means I need to show my notification above Notification area

This is possible but the way you implement it depends on the API level you develop for.
For API levels below 11, you can set Notification.FLAG_NO_CLEAR. This can be implemented like this:
// Create notification
Notification note = new Notification(R.drawable.your_icon, "Example notification", System.currentTimeMillis());
// Set notification message
note.setLatestEventInfo(context, "Some text", "Some more text", clickIntent);
// THIS LINE IS THE IMPORTANT ONE
// This notification will not be cleared by swiping or by pressing "Clear all"
note.flags |= Notification.FLAG_NO_CLEAR;
For API levels above 11, or when using the Android Support Library, one can implement it like this:
Notification noti = new Notification.Builder(mContext)
.setContentTitle("Notification title")
.setContentText("Notification content")
.setSmallIcon(R.drawable.yourIcon)
.setLargeIcon(R.drawable.yourBigIcon)
.setOngoing(true) // Again, THIS is the important line
.build();

To Create Non removable notification just use setOngoing (true);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_service_launcher)
.setContentTitle("My title")
.setOngoing(true)
.setContentText("Small text with details");

Sound like Notification.FLAG_NO_CLEAR or Notification.FLAG_ONGOING_EVENT is what you are looking for.

To Create Non removable notification just use setOngoing (true);
To Create removable notification just use setOngoing (false);

How to make a notification in Android that does not collapse itself?

The notification is now shown and hidden in the status bar after 2 seconds. How do I make the notification not go to the status bar?
val builder = NotificationCompat.Builder(context, "Over limit channel")
.setContentTitle("")
.setContentText("")
.setGroupSummary(false)
.setSmallIcon(R.mipmap.launcher_icon)
.setContent(remoteViews)
.setAutoCancel(false)
.setGroup("false")
.setGroupSummary(false)
.setContentIntent(pendingIntent)
.setPriority(NotificationCompat.PRIORITY_MAX)
val notificationManager = NotificationManagerCompat.from(context)
notificationManager.notify(800, builder.build())
The trick I found is to use the method setFullScreenIntent(android.app.PendingIntent intent,boolean highPriority) with this method the notification will never be removed from the status bar except when you do it yourself.
here is an example:
val intent = Intent()
val pendingIntent = PendingIntent.getActivity(context, 0, intent, 0)
val builder = NotificationCompat.Builder(context, "Over limit channel")
.setContentTitle("")
.setContentText("")
.setGroupSummary(false)
.setSmallIcon(R.mipmap.launcher_icon)
.setContent(remoteViews)
.setAutoCancel(false)
.setGroup("false")
.setGroupSummary(false)
.setContentIntent(pendingIntent)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setFullScreenIntent(pendingIntent,true)
From the android Studio documentation :
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.
Params: intent – The pending intent to launch. highPriority – Passing
true will cause this notification to be sent even if other
notifications are suppressed.
UPDATE
For some API version for this to work you must add this permission on the manifest
<uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT"></uses-permission>
You can start a foreground service with your required notification, or you can set the notification as an onGoing event to make it non dismissible

Oreo: Stop notification from getting removed on swipe

My Code:
mNotifyBuilder.setSmallIcon(R.drawable.ic_status_bar)
.setContentTitle("")
.setOngoing(true)
.setAutoCancel(false)
.setTicker("")
.setColor(ContextCompat.getColor(mContext, R.color.folderlist_bg_music))
.setChannelId(CHANNEL_ID)
.setContent(remoteViews).build();
Working fine on other phones, but not working on Vivo V7.
On first swipe the notification is removed and it reappears. But on second swipe, it dismisses completely.
Option 1:
You need to do the following way:
builder.setOngoing(true);
Option 2:
Notification notification = new Notification(icon, tickerText, when);
notification.flags = Notification.FLAG_ONGOING_EVENT;
Option 3:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_service_launcher)
.setContentTitle("My title")
.setOngoing(true)
.setContentText("Small text with details");
start a dummy foreground Service ...this will persist the notification while it's running.
A foreground service performs some operation that is noticeable to the user. For example, an audio app would use a foreground service to play an audio track. Foreground services must display a Notification. Foreground services continue running even when the user isn't interacting with the app.
Try adding this:
notification.flags |= Notification.FLAG_NO_CLEAR;
You can try the following:
builder.setOngoing(true); // Can't cancel your notification (except notificationManager.cancel(); )
Refer to this Ongoing notification
This is phone specific issue. Same thing works for other phones but not for Vivo phones.
OEMs shouldn't deviate from basic implementation that has been provided by stock Android.

How to make notification stay on top?

I have a notification which I always want to stay on top.
I have already given it a priority of 2
Mostly it stays on top but, suppose there is a open WiFi network, then my notification goes down and the notification of open WiFi network comes on the top position.
But when I looked at the notification of vlc(for Android) paying a song, the notification of vlc stay on top and the notification of open WiFi network goes down.
I notification is ongoing and with priority 2.
What should I do. I am a beginner so please bear with me.
And thanks in advance.
have you tried this
NotificationCompat.Builder builder =
(NotificationCompat.Builder) new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.notify_icon)
.setContentTitle("Notification")
.setContentText("ON Top")
.setPriority(Notification.PRIORITY_MAX);
Priority Levels --> PRIORITY_MAX / PRIORITY_HIGH /PRIORITY_DEFAULT /PRIORITY_LOW /PRIORITY_MIN

Android: How to create an "Ongoing" notification?
I think you can refer to this code:
Intent push = new Intent();
push.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
push.setClass(this, NotificationDemo.class);
PendingIntent pi = PendingIntent.getActivity(this, 0, push, PendingIntent.FLAG_CANCEL_CURRENT);
NotificationManager nm=(NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification updateNotification = new Notification.Builder(this)
.setSmallIcon(R.drawable.ic_face_black_24dp)
.setLargeIcon(BitmapFactory.decodeResource(this.getResources(), R.mipmap.ic_launcher))
.setContentTitle("Priority Max Notification Title")
.setContentText("Priority Max Notification Message")
.setAutoCancel(false)
.setDefaults(Notification.DEFAULT_SOUND)
.setPriority(Notification.PRIORITY_MAX)
.setFullScreenIntent(pi,true)
.build();
nm.notify("priorityMaxTest",2,updateNotification);

Notification using setFullScreenIntent() for BigTextStyle opening Activity automatically

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

Android Wear Notification is not displayed if FLAG_NO_CLEAR is used

If flag "FLAG_NO_CLEAR" is used the notification gets not displayed on the Android Wear.
Does anyone know why or any workaround? I didn't find any information in the documentation.
I need the flag "FLAG_NO_CLEAR" on my notifications and have Action button for "dismiss", "snooze" etc.!
Notification flag FLAG_NO_CLEAR basically makes your notification "ongoing". Ongoing notifications posted from phone will NOT be displayed on the wearable device.
You have two solutions to your problem - both of them have advantages and disadvantages. Please read text below and decide which solution will solve your situation better:)
Solution 1 - use group:
You can make use of group feature of Android Wear framework. It's basically created to post many (grouped) notifications on wearable device and one summary notification on phone. But using this mechanism you can also post one ongoing notification on your phone and second notification only on wear. You will end up with one ongoing notification on your phone and one normal notification on your wearable device.
final NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
// This notification will be shown only on phone
final NotificationCompat.Builder phoneNotificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Title phone")
.setContentText("Text phone")
.setOngoing(true)
.setOnlyAlertOnce(true)
.setGroup("GROUP")
.setGroupSummary(true);
// This notification will be shown only on watch
final NotificationCompat.Builder wearableNotificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Title wearable")
.setContentText("Text wearable")
.setOngoing(false)
.setOnlyAlertOnce(true)
.setGroup("GROUP")
.setGroupSummary(false);
notificationManager.notify(0, phoneNotificationBuilder.build());
notificationManager.notify(1, wearableNotificationBuilder.build());
This method will allow you to post an "alternative" notification for watch only, keeping your ongoing notification on phone. But (as mentioned earlier) the notification on watch cannot be ongoing - it has to be a normal notification. If you really want to have a true ongoing notification on watch you'll need to go for second solution.
Please read more about grouping (stacking) notifications here:
https://developer.android.com/training/wearables/notifications/stacks.html
Solution 2 - create wearable app:
Ongoing notifications from phone won't be shown on watch, but you can create wearable part of your Android application and post your notification directly on Android Wear. You can easily post an ongoing notification from there, but it won't be the same notification as is on phone. You will need to sync them between both devices.

Honestly something really weird changed in wear 1.5
so a solution would be to set an alarm
Uri alarmSound = getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Intent displayIntent = new Intent(this, WearNotif.class);
//displayIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent displayPendingIntent = PendingIntent.getActivity(this,
0, displayIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification = new Notification.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("WeirdShit")
.setContentText("some random crap")
.extend(new Notification.WearableExtender()
.setDisplayIntent(displayPendingIntent))
.setSound(alarmSound)
.build();
NotificationManagerCompat notificationManager =
NotificationManagerCompat.from(this);
notificationManager.notify(25454, notification);
