    public static String
getPath(Context context, Uri uri) {

 

        if ("content".equalsIgnoreCase(uri.getScheme()))

            String[]
projection = { "_data" };

            Cursor

            try {

                cursor

null,
null);

                int column_index

                if (cursor.moveToFirst())

                }

            }

Eat it

            }
