Android Question Help required on copying a file from DUCKDNS domain to Mobile

See this example: [Server] Upload files from your B4A app to your B4J server over the internet

Hi Erel,

I already saw that link and also had set up everything before typing above message.. I have also set up the duckdns update software and my domain also refreshes.. But I am unable to access it from the URL.. It is ramvenk.duckdns.org:54021 . I also tried adding www.ramvenk.duckdns.org:54021 but it is not working... I do not have a ROUTER .. Do I need to have a router for doing this ? ... Also need help on 2a) Can I get a code snippet on how to copy a file to my mobile from my server on duckdns domain to my PC. 2b) in which folder on my MOBILE should I copy that SQLLITE.DB file to ? ... Thanks

Have you opened the relevant port in your firewall?

The network should first be configured correctly.

Yes .. I have allowed Port 54021 in INBOUND as well as OUTBOUND on my firewall.. I am using Windows 7 .. Do I need to have a ROUTER for this ? .. I do not have any router . and ps. help on Question 2b) Which folder on my MOBILE should I copy the SQLLITE.DB file ? .. (where does it exactly reside) ..Sorry, if I am asking some very basic question.. I am unable to do this small thing (copying a file from a remote location to my mobile)...Thanks...

You can put it wherever you like. It doesn't matter.
