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

[beelze69]

Hi All,

1) Need some help on setting up DUCKDNS service My PC directly connects to internet via some Govt.
Broadband.. I have no router..I have enabled Port-forwarding on my Firewall. But it is not working.
Do I need to have a router for this ?
2) Also ..assuming I want to overwrite a sqllite database on my mobile with the latest file hosted on my
PC enabled via DUCKDNS on internet,
a) Can I get a code snippet on how to copy a file to my mobile from my server on duckdns domain to my PC
b) in which folder on my MOBILE should I copy that SQLLITE.DB file to ?

Thanks..

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?

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 ?

The network should first be configured correctly.

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...

Which folder on my MOBILE should I copy the SQLLITE.DB file ?

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