android ndk + curl / localhost file download problem

Issue

Downloading the localhost file using android ndk + lib curl.
The error code 7 occurring, but does the Android environment occur because it is an emulator?
How do I access localhost and receive files?
There seems to be no problem with the code.

ftp server env : windows iis curl test env : android adk emulator x86_64

Solution

The Android emulator does not see the host (Windows) computer as localhost. You can access the Web server by its external IP, or special 10.0.2.2 address.
