愉快的编码。在Android 10中，您不会尝试将uri转换为文件系统路径 即使您管理该路径，也基本上是不可访问的
您不是stackoverflow页面的普通读者，是吗？在Android 10中，您不会尝试将uri转换为文件系统路径 即使您管理该路径，也基本上是不可访问的
您不是stackoverflow页面的常客，是吗？tushar给出的上述答案是正确的，我已将该代码转换为kotlin，可能对其他人有所帮助

谢谢你的精彩和详细的回答！也许我错过了一些东西，但是如何修改它来获得视频缩略图的路径/uri？新的loadThumbnail方法实际上并没有为缩略图文件提供uri。谢谢您的精彩详细的回答！也许我错过了一些东西，但是如何修改它来获得视频缩略图的路径/uri？新的loadThumbnail方法实际上并没有为缩略图文件提供uri。
