Xamarin Media Manager Notification Controls

Question

Hello, I am trying to stream audio using MediaManager on Xamarin and the streaming is working, but I can't figure out how to customize the notification area when the audio is playing. The main things that I want to change is the notification area background, remove the "previous/next" controls, and change the text displayed. I think I need to use this for the controls CrossMediaManager.Current.NotificationManager.ShowNavigationControls = false; but it gives me the error "IMediaManager does not contain a definition for 'NotificationManager' and no accessible extension method 'NotificationManager' accepting a first argument of type 'IMediaManager' could be found". Thanks in advance!

Hello,

Welcome to our Microsoft Q&A platform!

If you want to custom the Notification UI, you can call the function of NotificationCompat.Builder to achieve it.For example, you can use NotificationCompact.BigPictureStyle to set a big picture notification.

You can refer to the following code:

        var valuesForActivity = new Bundle();  
        valuesForActivity.PutInt(COUNT_KEY, count3);  

        // When the user clicks the notification, SecondActivity will start up.  
        var resultIntent = new Intent(this, typeof(PicNotificationActivity));  

        // Pass some values to SecondActivity:  
        resultIntent.PutExtras(valuesForActivity);  


        // Construct a back stack for cross-task navigation:  
        var stackBuilder = TaskStackBuilder.Create(this);  
        stackBuilder.AddParentStack(Class.FromType(typeof(PicNotificationActivity)));  
        stackBuilder.AddNextIntent(resultIntent);  

        // Create the PendingIntent with the back stack:              
        var resultPendingIntent = stackBuilder.GetPendingIntent(0, (int)PendingIntentFlags.UpdateCurrent);  

        // Build the notification:  
        var builder = new NotificationCompat.Builder(this, CHANNEL_ID)  
                      .SetAutoCancel(true) // Dismiss the notification from the notification area when the user clicks on it  
                      .SetContentIntent(resultPendingIntent) // Start up this activity when the user clicks the intent.  
                      .SetContentTitle("Button3 Clicked") // Set the title  
                      .SetSmallIcon(Resource.Drawable.logo) // This is the icon to display  
                      .SetLargeIcon(BitmapFactory.DecodeResource(Resources, Resource.Drawable.pic1))  
                      .SetContentText($"The button has been clicked {count3} times."); // the message to display.  
                                                                                       // Instantiate the Big Text style:  
                                                                                       //Notification.BigTextStyle textStyle = new Notification.BigTextStyle();  
        builder.SetVisibility(NotificationCompact.VisibilitySecret);  
        if (Android.OS.Build.VERSION.SdkInt >= Android.OS.BuildVersionCodes.Lollipop)  
        {  
            builder.SetCategory(NotificationCompact.CategoryCall);  
        }  
        // Instantiate the Image (Big Picture) style:  
        NotificationCompact.BigPictureStyle picStyle = new NotificationCompact.BigPictureStyle();  

        // Convert the image to a bitmap before passing it into the style:  
        picStyle.BigPicture(BitmapFactory.DecodeResource(Resources, Resource.Drawable.pic1));  

        // Set the summary text that will appear with the image:  
        picStyle.SetSummaryText("The summary text goes here.");  

        // Plug this style into the builder:  
        builder.SetStyle(picStyle);  


        // Finally, publish the notification:  
        var notificationManager = NotificationManagerCompat.From(this);  
        notificationManager.Notify(NOTIFICATION_ID3, builder.Build());
