I've two android applications on same LAN provided by WIFI :
How to make it possible that (A) may do POST and GET requests on (B)?
What the URL used by (A) to access (B) looks like ?
Thanks to All.
You may confuse two different level of networking communication.
Level 4 : TCP connection between two sockets.
A logical pipe between to side (may be single(two process?) or two different computers)
only connection handling data are handle at this level
Level 7 : Browser / Application Server used particular communication "language" to exchange high level data (file , images, audio ..) and is handled at this level.
Your question is about to open a Listening Socket (level 4) and a client that talk with it with a HTTP protocol (level 7).
So you're miss to fill the gap socket listening side to handle HTTP protocol
May be a java web server implementation may help you.
a Java EE way to have HTTP server : "Tiny Java Web Server" @ http://tjws.sourceforge.net/ that may help you for what you're looking for
an "Apache" way to have HTTP server http://www.androiddevblog.net/android/a-bare-minimum-web-server-for-android-platform
