Grant permission access to 'All downloads' in Android

Question

I'm having trouble trying to access 'all downloads' to get its path. Here is my function to get the full path from a URI. I have tried to add android.permission.ACCESS_ALL_DOWNLOADS in androidManifest but it shows the below error. Does anyone know how to solve this problem? Any help is appreciated.

Code:

       if (isDownloadsDocument(uri)) {
           final String id = DocumentsContract.getDocumentId(uri);
            if (id != null && id.startsWith("raw:")) {
                return id.substring(4);
            }

            String[] contentUriPrefixesToTry = new String[]{
                    "content://downloads/public_downloads",
                    "content://downloads/my_downloads",
                    "content://downloads/all_downloads"
            };

            for (String contentUriPrefix : contentUriPrefixesToTry) {
                Uri contentUri = ContentUris.withAppendedId(Uri.parse(contentUriPrefix), Long.valueOf(id));
                try {
                    String path = getDataColumn(context, contentUri, null, null);
                    if (path != null) {
                        return path;
                    }
                } catch (Exception ignored) {}
            }

Error:

java.lang.SecurityException: Permission Denial: reading com.android.providers.downloads.DownloadProvider uri content://downloads/all_downloads/719 from pid=4604, uid=10438 requires android.permission.ACCESS_ALL_DOWNLOADS, or grantUriPermission()
