Android + Xamarin push notification custom sound will not play
<p>I've been working with the simple concept of playing a custom sound in my Android Xamarin app, but no matter what I try the sound will not play.</p>

<p>I have created a "raw" folder under Resources, and added an appropriate sound file.  I have made sure that file is being built as an Android resource.</p>

<p>Here's my code:</p>

<pre><code>// note I have also tried just /raw/NotificationSound, /integeridofresource and many other formats
string sSoundUrl = "android.resource://" + AppGlobals.PackageName + "/raw/NotificationSound.wav";

Notification nNotification = new Notification.Builder(this.Activity).SetSmallIcon(Resource.Drawable.AppIcon)
                .SetContentTitle("Test title")
                .SetContentText("Hello notifications")
                .SetAutoCancel(true)
                .SetSound(Android.Net.Uri.Parse(sSoundUrl)).Build();

// I have tried 0, All, NotificationDefaults.Sound basically all different  combinations
nNotification.Defaults = NotificationDefaults.Lights;

NotificationManager nmNotManager = (NotificationManager)this.Activity.GetSystemService(Context.NotificationService);

nmNotManager.Notify(0, nNotification);
</code></pre>

<p>I'm hoping somebody can spot what I'm doing wrong...</p>

<p>Thanks!!!</p>
