保存的视频未在Android画廊中显示9

Question

我在内部存储中存储视频，但保存的视频没有出现在画廊中。要查看首先，我必须打开文件经理，然后回到画廊。 视频

                        ContentResolver contentResolver = getContentResolver();
                        ContentValues contentValues = new ContentValues();
                        contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, "videoFileName");
                        contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "video/mp4");
                        contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_MOVIES);
                        Uri finalUriPath = contentResolver.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, contentValues);
                        File sourceLocation = new File(finalUri.getPath());
                    
                        InputStream in = new FileInputStream(sourceLocation);
                        FileOutputStream out = new FileOutputStream(String.valueOf(finalUriPath));
                        byte[] buf = new byte[1024];
                        int len;
                        while ((len = in.read(buf)) > 0) {
                            out.write(buf, 0, len);
                        }
                        in.close();
                        out.close();
                        contentValues.clear();
                        contentValues.put(MediaStore.Video.Media.IS_PENDING, 0);

                        StatusShowerActivity.this.getContentResolver().update(finalUriPath, contentValues, null, null);
                        Toast.makeText(StatusShowerActivity.this, "Saved", Toast.LENGTH_SHORT).show();

我使用Media Store在Android Q中存储了相同的
