我的流式音频播放器在通话过程中继续播放 – 无法让它停止！ （机器人）

我有一个由多个活动和一个服务组成的应用程序。 主要活动是用于流式传输音频的UI。 当用户按下播放按钮时，启动服务，流式传输音频和读取元数据。 然后，元数据被推送到UI（如果可见）和通知栏。 一切都按预期运行，直到打来电话。我曾经假设（愚蠢的是）通过使用标准的媒体播放器，android会处理流和电话本身之间的音频切换。 所以我创建了一个PhoneStateListener来处理调用并根据需要停止播放器。 我做错了，因为它仍然没有用。 如果您不介意查看服务类和日志文件，我真的很感激！

对不起，一切都那么冗长！

谢谢！ 金大中
