那些遇到过的问题

MediaPlayer错误(1,-1004)又称MEDIA_ERROR_IO试图在三星S3上播放音乐

mar*_*nke 18 streaming android android-mediaplayer samsung-mobile

注意:当我发布这个问题时,我不在我工作的公司工作,因此,即使可能会有一些很好的答案,我实际上也不会测试它们,因为我没有理由 (除了促进社区;这可能导致我有一天这样做).

但是,如果一些解决问题的办法是由许多其他comunity成员提拔,我可能会选择选择它作为问题正确答案经历了这么多年我最初发布这个问题之后.

与此同时,我希望有些答案可能会帮助你们中的一些人遇到这个问题.堆栈溢出!

我们的应用程序必须从在线资源中传播音乐(我不能自由地披露该来源).

为什么在S3上开始流式传输需要2分钟？

由于MEDIA_ERROR_UNKOWN,我已经能够弄清楚Media Player对象进入错误状态 - 很棒.对我帮助不大.因此,在使用OnErrorListener处理onError时,我重置了Media Player对象,然后调用startPlaying来完成剩下的工作 - 设置数据源等.

这个问题的答案在安装在运行Android 4.1.2的Samsung S III设备上的Android固件上出现了问题.

它似乎与流的来源有关,因为一些来源最终在设备上播放,但我们需要的,从未玩过.

如果你可以从其他来源获得你的流,它应该工作.

因此,如果您正在为特定公司/目的开发应用程序并对流的源进行一些控制,或者可以与控制流源的人进行通信,那么让他们将流的源更改为某些内容这将适用于运行Android 4.1.2的三星S III.

除此之外,所有解决此问题的方法都是固件升级.

对于每个努力解决这个问题的人来说,解决方案是:

Android MediaPlayer需要很长时间来准备和缓冲

编辑:以前的解决方案不是很完整,因为有时可能会在播放器暂停和恢复时听到播放器"口吃".

100%的Java回答略微优雅,包括使用MediaCodec实例将mp3转换为PCM数据以提供给AudioTrack实例.
