Here on InfinityFree, we provide website hosting only. Using our hosting for API services or content storage is not allowed, meaning you can only access pages on your account by actually visiting it in a browser. So contacting your script hosted here from an Android app is not possible.

If you want that kind of access, please upgrade your account to XVHOST.
