如何将android.net.Uri与“content：//”方案转换为java.net.URI

Question

如何将android.net.Uri与“content：//”方案转换为java.net.URI =＆gt;内容：//媒体/外部/视频/媒体/ 100767

我正在尝试将android.net.Uri转换为java.net.URI，如下所示：

URI javaUri = new URI(myAndroidUri.toString());

但是我收到了这个错误：

              java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=2, result=-1, data=Intent { dat=content://media/external/video/media/100767 (has extras) }} to activity {com.example.win.news/com.example.win.news.UploadNewsActivity}: java.lang.IllegalArgumentException: URI is not absolute: content%3A%2F%2Fmedia%2Fexternal%2Fvideo%2Fmedia%2F100767
