Is it possible..? and how to run http server in android?

Question

Android

In theory, you need to start the server whenever an Internet connection appears.

Answer 1

Yes. I even know how to do it.
First, select the server you need. The market is full of different http servers.
And you can run it when the Internet is visible through Tasker (crafty) !
There you can set up actions like:
(if I see the Internet) (do not care about home wi-fi or fast 3g, but not GPRS / EDGE) (launch such an application)

Answer 2

Download FileExpert. There you can raise both ftp and http

Answer 3
