Я создаю приложение для галереи, и я попытался удалить изображение в mediastore с помощью contentResolver().delete() . но он выдает исключение. Как я могу это решить? Я использую API 29.

Мой код:

 public static void removeFile(Context context, String uriStr) {
    Uri uri = Uri.parse(uriStr);
    context.getContentResolver().delete(uri, null, null);
}
