Welcome to AF! you may have more luck with your question in our Application Development forum.

I dont know much about FTP, but 505 means the server doesnt support the version of protocol you are using I think.

[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]505 HTTP Version Not Supported

The server does not support, or refuses to support, the HTTP protocol version that was used in the request message. The server is indicating that it is unable or unwilling to complete the request using the same major version as the client other than with this error message. The response SHOULD contain an entity describing why that version is not supported and what other protocols are supported by that server. [/FONT]

from: Server Error Codes

It seems like the server doesnt support FTP over an HTTP string as per this site:

nsftools - Java FTP Tips
This method can work if:

  • the site supports it
  • you know exactly what file you need and where it is
  • you don't have to do anything other than just download a file

505 makes me think that the server doesnt support the method you are using.

Have you tried asking in the development forum that alostpacket linked before (Application Development - Android Forums)? I think that what you're asking is a little beyond what most normal users are capable of...
