问题 I’m using MediaElement for playing videos and BackgroundAudioPlayer for playing audio. Here is a case. I’m playing remote audio via BackgroundAudioPlayer. Then I want to play video and before MediaElement begins playing video I’m calling BackgroundAudioPlayer.Close as suggested in BackgroundAudioPlayer best practices. MediaElement and the BackgroundAudioPlayer Care must be taken when mixing BackgroundAudioPlayer and MediaElement for audio playback. 1. Close() must be called before switching

问题 around a week ago, I submitted an online Background Radio Streaming app for the Windows Phone store. The app was quite good (as I used the Emulator to test it, it was good on all the possible sectors) but when I submitted it for certification, it failed. According the the error log, if someone is already playing a Music from Music + Video hub and then tries to open this app, both of the apps Crash and stop unexpectedly. So far I understood, it is because the Music of Music + Video hub is also

问题 I want to hide all the controls on the locked screen when an app is playing in the background. However, I want the audio related information to be displayed all the time. I read about MPRemoteCommandCenter but we can't implement the below code because when you try to disable all then the screen starts showing 3 controls (toggle button, next track, previous track) MPRemoteCommandCenter *rcc = [MPRemoteCommandCenter sharedCommandCenter]; [[rcc skipForwardCommand] setEnabled:NO]; [[rcc

问题 If anyone has developed WP apps before you know that you can't pass certification if your app stops music that is currently playing without the users consent. I did see this question here which might have worked for WP7 apps but it apparently doesn't work for WP8. I assume it doesn't work because the WP8 OS doesn't support XNA (It is only backward compatible, and if you developed the app using 7.1). Has anyone come across the solution for detecting background music in WP8. 回答1: I believe

问题 I'm using Background Audio Player on Windows Phone 8 and I'm trying to set an album art for my audio track. As I've read here and at MSDN the image MUST be at shared/media/ - ok I've checked the image is there and I try to do: AudioTrack myTrack = new AudioTrack(track.source, track.Title, track.Artist, track.Album, new Uri("shared/media/Episode29.jpg", UriKind.Relative)); The music starts, but there is no image. Am I doing something wrong? I've also run Background Audio Player Sample
