SetSound - This API is now obsolete. What to use?
Can i use .SetDefaults (Resource.Drawable.MYSOUNDMP3) in
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID)
.SetContentTitle ("Sample Notification")
.SetContentText ("Hello World! This is my first notification!")
.SetDefaults (NotificationDefaults.Sound)
.SetSmallIcon (Resource.Drawable.ic_notification);
I did like this, everything works.
i create channel
if (Build.VERSION.SdkInt < BuildVersionCodes.O)
{
// Notification channels are new in API 26 (and not a part of the
// support library). There is no need to create a notification
// channel on older versions of Android.
return;
}
string name = "MyName";
var description = "Notice";
var channel = new NotificationChannel(CHANNEL_ID, name, NotificationImportance.High)
{
Description = description
};
var soundUri = Android.Net.Uri.Parse($"{ContentResolver.SchemeAndroidResource}://{Application.Context.PackageName}/{Resource.Drawable.mysound}");
var audioAttributes = new AudioAttributes.Builder()
.SetContentType(AudioContentType.Sonification)
.SetUsage(AudioUsageKind.Notification)
.Build();
channel.SetSound(soundUri, audioAttributes);
var notificationManager = (NotificationManager)GetSystemService(NotificationService);
notificationManager.CreateNotificationChannel(channel);
i create notification
var builder = new NotificationCompat.Builder(this, CHANNEL_ID)
.SetContentTitle(SetContentTitle)
.SetContentText(SetContentText)
.SetChannelId(CHANNEL_ID)
.SetSmallIcon(Resource.Drawable.icon);
// Finally, publish the notification:
var notificationManager = NotificationManagerCompat.From(this);
// Publish the notification:
int notificationId = 1;
notificationManager.Notify(notificationId, builder.Build());
changed the AudioUsageKind.Alarm to AudioUsageKind.Notification
You can use NotificationChannel instead of NotificationCompat.Builder
NotificationChannel mChannel;
if (Build.VERSION.SdkInt >= Android.OS.BuildVersionCodes.O)
{
mChannel = new NotificationChannel(CHANNEL_ID, Utils.CHANNEL_NAME, Android.App.NotificationImportance.High);
string description = getString(R.string.channel_description);
mChannel.LightColor(Color.GRAY);
mChannel.EnableLights(true);
mChannel.Description=description ;
var audioAttributes = new AudioAttributes.Builder()
.SetContentType(AudioContentType.Sonification)
.SetUsage(AudioUsageKind.Alarm)
.Build();
var alarmUri = Android.Net.Uri.Parse("MyApp.Android/Resources/raw/alarm.mp3");
mChannel.SetSound(soundUri, audioAttributes);
if (mNotificationManager != null)
{
mNotificationManager.createNotificationChannel(mChannel);
}
}

SetSound is deprecated on the Android side starting from API level 26. You can read more about it in official Android API documentation
As documentation suggests you can use NotificationChannel's SetSound instead.
You can find a sample how to use NotificationChannels in Xamarin here
SetSound was deprecated on Android from API level 26
SetDefaults should be replaced with the use of the following
NotificationChannel.EnableVibration(boolean)
NotificationChannel.EnableLights(boolean)
NotificationChannel.SetSound(Uri, AudioAttributes)
setSound should be replaced with use of
NotificationChannel.SetSound(Uri, AudioAttributes)
Check the official documents by Android for more information:
https://developer.android.com/reference/android/app/Notification.Builder.html#setDefaults(int)
https://developer.android.com/reference/android/app/Notification.Builder#setSound(android.net.Uri)

I have UWP Windows application, developed under the Xamarin.forms. I have implemented the Toast notifications but I am facing the issue with this. In some Windows 10 systems, it is working and showing the toast notification properly, but in some of the Windows 10 systems (even having the same Windows 10 OS update) it is not working.
Below first code snippets that I have implemented in the Native UWP.
string msg = "Toast Notification Header";
string subMsg = "Toast Notification Title";
var toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText02);
var toastTextElements = toastXml.GetElementsByTagName("text");
toastTextElements[0].AppendChild(toastXml.CreateTextNode(msg));
toastTextElements[1].AppendChild(toastXml.CreateTextNode(subMsg));
//To play the custom sound
var toastNode = toastXml.SelectSingleNode("/toast");
var audio = toastXml.CreateElement("audio");
audio.SetAttribute("src", "ms-appx:///Assets/incoming_message.wav");
audio.SetAttribute("loop", "false");
toastNode.AppendChild(audio);
var toast = new ToastNotification(toastXml);
ToastNotificationManager.CreateToastNotifier().Show(toast);
Below second code snippets that I have implemented in the Native UWP.
// "With Microsoft.Toolkit.Uwp.Notifications"
// Construct the toast content
ToastContent toastContent = new ToastContent()
{
Visual = new ToastVisual()
{
BindingGeneric = new ToastBindingGeneric()
{
Children =
{
new AdaptiveText()
{
Text = "Toast Notification Header"
},
new AdaptiveText()
{
Text = "Toast Notification Content"
}
}
}
}
};
bool supportsCustomAudio = true;
// If we're running on Desktop before Version 1511, do NOT include custom audio
// since it was not supported until Version 1511, and would result in a silent toast.
if (AnalyticsInfo.VersionInfo.DeviceFamily.Equals("Windows.Desktop")
&& !ApiInformation.IsApiContractPresent("Windows.Foundation.UniversalApiContract", 2))
{
supportsCustomAudio = false;
}
if (supportsCustomAudio)
{
toastContent.Audio = new ToastAudio()
{
Src = new Uri("ms-appx:///Assets/incoming_message.wav")
};
}
// And create the toast notification
ToastNotification notification = new ToastNotification(toastContent.GetXml());
// And then send the toast
ToastNotificationManager.CreateToastNotifier().Show(notification);
Above code snips showing the Toast notification in some Windows 10 system and not working in some other Windows 10 system.
Kindly guide me on this. Thanks in advance.

Please follow these steps to add toast notification in UWP Project.
Step 1:- Create a new UWP project.
Step 2:- Go to the code-behind and add the namespace.
using Windows.UI.Notifications;
using
NotificationsExtensions.Toasts;
Step 3:- I created a Toast Generic Template like the following code:
public static Windows.Data.Xml.Dom.XmlDocument CreateToast()
{
var xDoc = new XDocument(
new XElement("toast",
new XElement("visual",
new XElement("binding", new XAttribute("template", "ToastGeneric"),
new XElement("text", "C# Corner"),
new XElement("text", "Do you got MVP award?")
)
),// actions
new XElement("actions",
new XElement("action", new XAttribute("activationType", "background"),
new XAttribute("content", "Yes"), new XAttribute("arguments", "yes")),
new XElement("action", new XAttribute("activationType", "background"),
new XAttribute("content", "No"), new XAttribute("arguments", "no"))
)
)
);
var xmlDoc = new Windows.Data.Xml.Dom.XmlDocument();
xmlDoc.LoadXml(xDoc.ToString());
return xmlDoc;
}
Step 4:- Create a toast notification object using XML document.
var xmdock = CreateToast();
var toast = new ToastNotification(xmdock);
Next show the toast using ToastNotificationManager class.
var notifi = Windows.UI.Notifications.ToastNotificationManager.CreateToastNotifier();
notifi.Show(toast);
Step 5:- C# code-behind:
private void showToastBtn_Click(object sender, RoutedEventArgs e)
{
var xmdock = CreateToast();
var toast = new ToastNotification(xmdock);
var notifi = Windows.UI.Notifications.ToastNotificationManager.CreateToastNotifier();
notifi.Show(toast);
}
I hope the above code will be useful for you.
Thank you
i have xamarin forms app that support notification, i have done it in android with broadcast receiver now i have to do notification in ios ! , my service is depending on API REST so i want every 60 second ios app run HTTP request and get data then show it as notification, i searched for many days but i can't reach to my approach ?
if this is impossible can i use nuget or something like that in ios project only "in xamarin forms solution " or not ?
content = new UNMutableNotificationContent();
content.Title = "Notification Title";
content.Subtitle = "Notification Subtitle";
content.Body = "This is the message body of the notification.";
content.Badge = 1;
content.CategoryIdentifier = "message";
var trigger = UNTimeIntervalNotificationTrigger.CreateTrigger(60, true);
var requestID = "sampleRequest";
var request = UNNotificationRequest.FromIdentifier(requestID, content, trigger);
UNUserNotificationCenter.Current.AddNotificationRequest(request, (err) =>
{
if (err != null)
{
// Do something with error...
}
});
Here is my code for generating a local notification on iOS
var alertsAllowed = false;
UNUserNotificationCenter.Current.GetNotificationSettings((settings) =>
{
alertsAllowed = (settings.AlertSetting == UNNotificationSetting.Enabled);
});
if (alertsAllowed)
{
var content = new UNMutableNotificationContent();
content.Title = "Incident Recorder";
content.Subtitle = "Not Synchronised";
content.Body = "There are one or more new incidents that have not been synchronised to the server.";
var trigger = UNTimeIntervalNotificationTrigger.CreateTrigger(5, false);
var requestID = "sampleRequest";
var request = UNNotificationRequest.FromIdentifier(requestID, content, trigger);
UNUserNotificationCenter.Current.AddNotificationRequest(request, (err) =>
{
if (err != null)
{
Console.WriteLine(err.LocalizedFailureReason);
}
});
}
The first parameter in CreateTrigger is how long before the notification is generated. I notice you have 60 in yours. Also bear in mind a notification will not appear if your app is foregrounded.
I'm implementing a notification system using Xamarin platform, which extends to wearable devices to send the notification. I also want to get the input of user from the wear notification and i have programed it in such away that user can select text or use voice. i followed the following tutorial
http://developer.android.com/training/wearables/notifications/voice-input.html
my code is:
void SendWearNotification (string message, string from)
{
var valuesForActivity = new Bundle();
valuesForActivity.PutString ("message", message);
String groupkey = "group_key_emails";
var intent = new Intent (this, typeof(MyMainActivity));
intent.PutExtras (valuesForActivity);
intent.AddFlags (ActivityFlags.ClearTop);
var pendingIntent = PendingIntent.GetActivity (this, 0, intent, PendingIntentFlags.OneShot);
var builder = new NotificationCompat.Builder (this)
.SetAutoCancel (true)
.SetContentIntent (pendingIntent)
.SetContentTitle (from)
.SetSmallIcon (Resource.Drawable.Iconlogo)
.SetContentText (message) //message is the one recieved from the notification
.SetTicker(from)
.SetGroup (groupkey) //creates groups
.SetPriority((int)NotificationPriority.High);
//
//for viewing the message in second page
var pagestyle= new NotificationCompat.BigTextStyle();
pagestyle.SetBigContentTitle (from)
.BigText (messagefromapp); //message from app is the one rerieved from the wcf app
//second page
var secondpagenotification = new NotificationCompat.Builder (this)
.SetStyle (pagestyle)
.Build ();
//intent for voice input or text selection
var wear_intent = new Intent (Intent.ActionView);
var wear_pending_intent = PendingIntent.GetActivity (this,0,wear_intent,0);
// Create the reply action and add the remote input
setRemoteInput ();
var action = new NotificationCompat.Action.Builder (Resource.Drawable.ic_mes,
GetString (Resource.String.messages), wear_pending_intent)
.AddRemoteInput (remoteinput)
.Build ();
//add it to the notification builder
Notification notification = builder.Extend (new NotificationCompat.WearableExtender ()
.AddPage (secondpagenotification).AddAction(action)).Build ();
//create different notitfication id so that we can as list
if(notification_id<9){
notification_id += 1;
}else{
notification_id=0;
}
var notificationManager = (NotificationManager)GetSystemService(Context.NotificationService);
notificationManager.Notify (notification_id+2, notification);
}
this method is implmented inside GCMListnerService class.
According to the tutorial from the above link, i can retreive the input data user selected or spoke uing the following code:
private void getResponse(Intent intent){
Bundle remoteInput = RemoteInput.GetResultsFromIntent(intent);
if (remoteInput != null) {
Toast.MakeText(this, remoteInput.GetCharSequence(EXTRA_VOICE_REPLY), ToastLength.Short);
}
//return null;
}
My question is when do i call this method, how do i know if user have selected a text en send from the wearable device. if there is any event which i can use.
I got the solution. the method the gets the remote input (the "getresponse" in my case) should be called from the "Oncreate" method of an activity that is used when the notification is created. In my case the actvity i used is "MyMainActivity" when i create the intent of the notification as u can see it in the code. So this means the method will be called twice, when the application runs, and when user reponds from the wear. but ony in the second case will the "remoteinput.getResultfromIntent" will have a value. I hope it will help for someone with same issues.
