    I'm successfully implementing a method for retrieving the real path of an image from gallery by the Uri returned from ACTION_PICK intent.

    That code may not work for all images. There is no requirement for DATA to point to a filesystem path that you can access.

    Just like this answer.

    FWIW, this was my answer to that question.

    Only thing i found is this question. Didn't find a proper answer there though.

    That technique wasn't particularly good and will no longer work, as Android has locked down /proc.

    In the official docs, they recommend to use FileDescriptor instead, problem is i don't know exactly how.

    The more general concept is that you use ContentResolver to work with the Uri, whether you get an InputStream (openInputStream()), OutputStream (openOutputStream()), or FileDescriptor. Consume the content using those things. If you have some API that absolutely needs a file, copy the content (e.g., from the InputStream) to a file that you control (e.g., in getCacheDir()).

    As a bonus, now your code is also in position to use the Storage Access Framework (e.g., ACTION_OPEN_DOCUMENT) and the Internet (e.g., OkHttp), if and when that would be useful.
