     if (BackgroundAudioPlayer.Instance != null &&
         BackgroundAudioPlayer.Instance.Track.Source.ToString().Contains("Claps.mp3"))
     {

     }
 }

Answer 1

您的Windows Phone 8.0 Silverlight代码在Windows Phone 8.1 XAML中不起作用，因为API不同，没有BackgroundAudioPlayer.Instance，没有BackgroundMediaPlayer.Current和更多不同之处，请查看https://msdn.microsoft.com/ EN-US /库/窗/应用/ XAML / dn642090.aspx
