How to convert URI to real path in marshmallow?

I have an image URI and I want to convert this URI to a real path. I've looked at lot of of answers but none worked for me. I'm using marshmallow 6.0.1. The image URI is content://com.android.providers.media.documents/document/image%3A52530.

Code:

   sendImageFromFolder.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                     Intent intent = new Intent();
                    intent.setType("image/*");
                    intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);

                }
            });

     protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);

     if(requestCode==1) {
          Uri uri = data.getData();//how to convert this uri to real path .
    }

    }

A Uri is not a File. A Uri does not have to represent a file on the filesystem that you can access. The Uri might point to content that is:

stored on removable storage, which you cannot access
stored on internal storage of another app, which you cannot access
stored in an encrypted form, where a ContentProvider needs to decrypt it
stored in a BLOB column of a SQLite database, where a ContentProvider needs to load it and serve it
stored in "the cloud", where a ContentProvider needs to download it
generated on the fly, the way this Web page is
and so on

You can use ContentResolver and openInputStream() to get an InputStream on the content represented by the Uri. You can create a FileOutputStream on some file that you control. And, you can use Java I/O to copy from the InputStream to the OutputStream, making your own copy of the content in a file that you control.
