I have built an cross-platform app that involves playing audio (podcast mp3 files) in the background.

I have followed the examples as best as I can for performing background audio on Windows Phone 8.1 XAML apps. It will launch and try to start sometimes giving a second or two of audio, and then I get this in the output:

The program '[3284] Windows.Media.BackgroundPlayback.exe' has exited with code 1 (0x1).

I don't even know where to look from here. It doesn't seem to raise an actual exception in the application itself. Any idea what is wrong or how to further troubleshoot this?

请检查以下项目：

  1. 您将完整的类名传递到Package.appxmanifest中（参见此处的示例）
  2. 您从主项目中引用了任务项目（下载Microsoft 示例并尝试复制项目引用的想法）
  3. 两个项目具有相同的 Windows Phone 版本（例如 8.1、10 等）
  4. 任务项目具有输出类型Windows 运行时组件（不是类库）
  5. 当然：尝试删除除后台任务之外的所有文件并再次重复上述项目。

在我的情况下，问题是通过卸载已安装的应用程序并再次部署来解决的。
