Recently I had to demo our android product and for that I was looking for some best tool to share real device screen on the computer so that from there I can share it on projector.
After doing some research I was able to find a very good open source tool named “webkey” (http://androidwebkey.com/). Its really awesome. There is no hassle of setting up things. You need just install their app from android market and there you go!
Download its android app from here https://play.google.com/store/apps/details?id=com.webkey and just start its service. Now your device screen would be available on entering IP address of your phone in browser.
