使用NPR StreamProxy实现时出现MediaPlayer错误

Question

我正在尝试使用NPR方法通过StreamProxy和PlaybackService类来流式传输音频，流是一个音频/aac文件。

http://code.google.com/p/npr-android-app/source/browse/trunk/Npr/src/org/npr/android/news/PlaybackService.java

( streamProxy.Java与上面的路径相同，无法在帖子中包含两个链接)

但是我得到了一个错误。我得到的日志是

有没有人能告诉我我哪里错了。

哈里，向你致敬

Answer 1

只是为了回答我自己的问题。

无法通过NPR Streamproxy方法播放AACP流。不过，它们在mp3 streams上确实工作得很好。
