我创建了一个应用程序，它在启动时在后台播放歌曲，当我在 Eclipse 中执行它时它工作正常，但是一旦我将应用程序转移到我的手机上，歌曲就不再播放了？
关于我应该做什么的任何建议/解决方案？谢谢！

Throwing out the simple things. Have you verified volume is all the way up and that the music file was also successfully transferred to the device? Is the music file located at the path where the program expects it to be? Can you connect the device and use the debug tool to step through the application while running on the device?
