I am using
Xamarin + firebase notification for cross platform app
Need
To change the default notification sound
Expect
The sound changed, even if the app is colse. Which means I will assign a different tone for the notifications which come to this app
Coding
No need to write any code to play the sound or to trigger the on notofication recieved event at all
Current result:
I success to do this with IOS only, but faild with Android.
Now I can recieve notification with custom sound even if the app is closed, without writting any code for this
My code
For IOS
1- add this line to the notification payload
"sound": "test.wav"
only sound name with the extention
2- add test.wav to IOS project under Resources as "BundleResource", or "Embedded Resource"
3- send the notification, and do not care about "NotificationRecieved" event at all
4- kill the app, and send the notification
5- notification recieved with custom sound "test.wav"
6- IOS accect "wav" or "caf" files only
For Android
Repeat the same with "wav" file, but with some changes like:
1- the sound file add at Resources/raw as AndroidResource For Project.Droid
2- try to change the payload to be:
"sound": "test.wav"
"sound": "test"
"sound": "raw/test.wav"
"sound": "raw/test"
But never success to play the sound
Question
I am sure there is something wrong in the ("sound": "test.wav") format.
I tested it with and without extention,
I do not need to handle the sound by coding, I want to assign the tone exactly as done with the IOS project
I expected IOS to be harder than Android! but at end it was easy
Any help, please?
Finally, I solved it.
For those who face the same problem I will post the solution.
For IOS, you can only pass the sound file name as I said before.
For Android, it is comples. I noticed that the app uses the default system sound for all notification which recieved in the background mode, closed, or killed app.
I went to the app settings, then I found a channel name "Miscellaneous" which used for such notifications.
The idea was how to change this channel sound?
If you create a channel with the same name, it will not work because you have to use channel name + channel ID.
I searched and finaly find the default channel id which is "fcm_fallback_notification_channel".
The second step was to create a channel with this name and id, in hope to override the system one.
I created this channel in the app start with the following code:
var importance = NotificationImportance.High;
var soundFileName = "sound";
NotificationChannel chan = new NotificationChannel("fcm_fallback_notification_channel", "Miscellaneous", importance);
chan.EnableVibration(true);
chan.LockscreenVisibility = NotificationVisibility.Public;
chan.SetSound(Android.Net.Uri.Parse("android.resource://com.myapp.test/raw/" + soundFileName), null);
NotificationManager notificationManager = (NotificationManager)GetSystemService(NotificationService);
notificationManager.CreateNotificationChannel(chan);
And it works as expected :)
Now I can recieve nottifications with the custom sound even if the app is closed, killed, or background mode.
I did not think that I can do this, finally.
Thanks for everyone.
Hope this can help someone.
For the Android, you should set the sound in NotificationChannel
var channel = new NotificationChannel(CHANNEL_ID, "FCM Notifications", NotificationImportance.Default)
{
Description = "Firebase Cloud Messages appear in this channel"
};
var audioattributes = new AudioAttributes.Builder();
audioattributes.SetContentType(AudioContentType.Music);
audioattributes.SetUsage(AudioUsageKind.Notification);
channel.SetSound(global::Android.Net.Uri.Parse("android.resource://" + this.ApplicationContext.PackageName + "/raw/app_sound"), audioattributes.Build());
Note: If you set it, please uninstall the app to alter sound settings, Check out these link for more details.
I am using a NotificationChannel to define my app's notification. I set it's sound with the following code :
AudioAttributes.Builder constructeurAttributsAudio=new AudioAttributes.Builder();
constructeurAttributsAudio.setUsage(AudioAttributes.USAGE_NOTIFICATION_EVENT);
canalNotification.setSound(Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + contexte.getPackageName() + "/raw/cloche"),constructeurAttributsAudio.build());
When the notification appears, the sound is correctly emitted, but it's volume is set at the maximum and doesn't take into account the sound level set for notifications by the user. Does anyone know how I can have my app set the notification sound level to the value choosen by the user?
Edit #1 : if I copy the code to execute it in the app's body (triggered by a Button click) instead of in the onReceive method of my BroadcastReceiver, the notification sound is correctly emitted at the sound level chosen by the user for notifications.
Edit #2 : strangely, the notification sound level is correct when the app is executed on the emulator! Could the reason be a parameter in the phone's configuration? (They both run under Android 9).
Uninstalling and reinstalling the app solved the problem!
I use the following code, hopefully useful for you too:
private void setvolume(int volume)
{
AudioManager manager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
manager.setStreamVolume(AudioManager.STREAM_MUSIC, volume, 0);
Uri notification = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
MediaPlayer player = MediaPlayer.create(getApplicationContext(), notification);
player.start();
}
a while back I updated my App to add support for Android 8+, after updating the notifications to use the required NotificationChannel I noticed that I lost a feature.
The App uses a chronometer notification, back then I was able to update the Notification priority, to display a notification using PRIORITY_HIGH, so the notification was "pushed" to the user, and then edit the notification priority to PRIORITY_LOW, to hide the notification.
After reading the docs, from what I could understand, I can't control the priority after creating the NotificationChannel, leaving this control to the user, however, asking for the user to edit the notification settings is not optimal for my usage.
Relevant code:
//Creating the notification channel (while setting up the app)
NotificationChannel channel = new NotificationChannel(channelId, channelTitle, NotificationManager.IMPORTANCE_HIGH);
//Editing the NotificationChannel to lower the Notification priority (not working)
NotificationChannel channel = notificationManager.getNotificationChannel(channelId);
channel.setImportance(NotificationManager.IMPORTANCE_LOW);
notificationManager.createNotificationChannel(channel);
Is there a way accomplish this behavior, while still using the NotificationChannels?
Turns out I was overthinking this (by a lot), simply adding the option
setOnlyAlertOnce on the NotificationBuilder, while still using the NotificationManager.IMPORTANCE_HIGH to setup the channel, will result on the expected behavior, like so:
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(context, channelId).setOnlyAlertOnce(true);
I have a foreground service that shows a progress notification and if it is finished, the notification is reused as a normal notification to show the service's result
I allow the user to define inside my app if the final notification is silent or not. So here is what I do:
// 1) Create notifcation channel in my app, once only
NotificationChannel notificationChannel = new NotificationChannel(channelId, channelName, importance);
notificationChannel.enableLights(false);
notificationChannel.enableVibration(true);
notificationManager.createNotificationChannel(notificationChannel);
// 2) Init notification
notificationBuilder = new NotificationCompat.Builder(this, notificationChannelId);
notificationBuilder.setAutoCancel(false);
notificationBuilder.setOngoing(true);
notificationBuilder.setTicker(ticker);
notificationBuilder.setContentText(title);
// 3) Updating the notification to show the services progress
notificationBuilder.setContentTitle(title);
notificationBuilder.setContentText(subTitle);
// 4) preparing the final notification
if (!MainApp.getPrefs().silentNotifications()) {
if (globalError || updated > 0 || prepared > 0 || contactsWithError.size() > 0) {
notificationBuilder.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE);
notificationBuilder.setVibrate(new long[]{0, 500});
notificationBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
} else {
notificationBuilder.setVibrate(new long[]{});
notificationBuilder.setSound(null);
}
}
Problems
an android oreo user told me, the notification is making a sound/vibrates on each update
the same user told me, after a restart, the sound/vibration is gone
What I want
I want that the notification channel vibrates and plays a sound by default (if the user did not change this in the android settings for my channel)
I want to dynamically decide that I don't play sounds/vibrate even if sound/vibration is enabled
If the user disables sound/vibration for my channel, I'm fine, than I won't play a sound nor vibrate at any time
How am I supposed to achieve that?
Edit - one solution is following:
Use two channels:
one for updating the notification
one for the final result notification.
This looks weird to me, I would assume that I can use one channel, set it up with sounds by default and use this channel. I should be able to define myself to play a sound or not, if the user allows me to play a sound (seems like I'm forced to play a sound currently). Otherwise I never play a sound of course. It looks like currently you need two channels for every service, that shows progress in the notification and plays a sound by default if finished. That's bad to explain to the user because you need two channels for the same action, on for the progress and one for the final result...
I was annoyed with the sound of my notifications. I did this.
.setSound(Uri.parse("android.resources://" + getPackageName() + "/" + R.raw.silence))
and this
.setOnlyAlertOnce(true)
Also note that you have to set them in the channel too.
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);
