如何在 Android 10 及更高版本中获取共享存储文件夹的文件路径？

Question

We are integrating scoped storage in our app, we are reading and writing video files in sahred storage eg Environment.DIRECTORY_MOVIES folder (shared storage movies directory) it is working as expected but we need to write custom metadata in video to do that we are using org.mp4parser:isoparser . To read and write metadata, this library needs file object before scoped storage we can get absolute path using Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES) now it's deprecated is there any other way to get the file path in scoped storage?

public static String readVideoMetadata(File videoFile) throws IOException {
    
        if (!videoFile.canRead()) {
            throw new IllegalStateException("No read permissions to file " + videoFile.getAbsolutePath());
        }
        if(!isImageFile(videoFile)) {
            try {
                IsoFile isoFile = new IsoFile(videoFile);
                if (null != Path.getPath(isoFile, "moov[0]/udta[0]/meta[0]/ilst/©cmt")) {
                    AppleCommentBox nam = Path.getPath(isoFile, "moov[0]/udta[0]/meta[0]/ilst/©cmt");
                    String xml = nam.getValue();
                    isoFile.close();
                    return xml;
                }
            } catch (OutOfMemoryError | Exception e) {
                e.printStackTrace();
            }
        }else{
            ExifInterface exifInterface=new ExifInterface(videoFile);
            String metaData= exifInterface.getAttribute(ExifInterface.TAG_USER_COMMENT);
            if(metaData!=null){
                return metaData;
            }
        }
    
        return "";
    }

Use FFMPEG Android library

You can get file path from media URI using the below code

Uri safUri = intent.getData();
String inputVideoPath = FFmpegKitConfig.getSafParameterForRead(requireContext(), safUri);

You can read media information using this below function

 MediaInformationSession mediaInformation = FFprobeKit.getMediaInformation("<file path or uri>");
mediaInformation.getMediaInformation();
