Android 如何将解析文件转换为可播放的3GP文件

我正在开发一个从www.parse.com上传和下载音频文件的应用程序。我把它们上传为parseFile，它工作得很好。 当我下载parseFile时，如何将其转换为我的android可以播放的内容

---

注意：我以.3gp格式上传文件。您可以使用

getData（）

方法将

ParseFile

转换为

Byte[]

然后，您可以通过使用此功能和一些编辑（从）从

字节[]

播放歌曲：

正如您在链接中看到的，3GPP很好。您只需使用mime类型发布文件，以指示它是什么。请参阅使用parserestapi发布带有“contenttype”头的音频的curl代码

当您执行GET时，它应该与mimeType一起提供，并且媒体播放器应该能够通过对解析文件的URL引用来处理它

因此，请尝试上载这些标题，然后使用响应中的URL加载到MediaPlayer

太多了！工作得很漂亮！
