Thanks for your answer but I am finding source code

A google for "android ip webcam github" gives you several options...

OpenTok works best for me !! You must give it a try !

PS. The guy has very nice bunch of tutorials in every aspect of Android. 

I guess you are looking something like ipcamera (you want to capture video by your android camera and stream that video on server) if yes?

hope this would help you.
