Как получить реальный путь к изображению с помощью URI без MediaStore.Images.Media.DATA

Question

Я обнаружил, что MediaStore.Images.Media.DATA устарело, поэтому я хочу использовать другой способ получить реальный путь к изображению.

Вот мой новый способ получить URI и заголовок изображения, но я не знаюкак получить реальный путь.

Я печатаю URI, название, путь:

photoUri: содержимое: // media / external / images / media / 1605

title: IMG_20191223143418

photoUri.getPath: / external / images / media / 1605

Но я хочу просто так: /storage/emulated/0/DCIM/1733/IMG_20191223143418.jpg

public static String getRealPathFromUri(Context context, Uri uri) throws IOException {

    String filePath = null;

                String documentId = DocumentsContract.getDocumentId(uri);
                if (isMediaDocument(uri)) { // MediaProvider.
                    String id = documentId.split(":")[1];

                    String selection = MediaStore.Images.Media._ID + "=?";
                    String[] selectionArgs = {id};

                    filePath = getDataColumnImage(context, MediaStore.Images.Media.EXTERNAL_CONTENT_URI, selection, selectionArgs);

просто используйте этот метод getImagePath (); открытый класс RealPathUtil {
