After creating a new phonegap project (I use phonegap-cli) or check this link [http://docs.phonegap.com/getting-started/1-install-phonegap/cli/].
Copy config file from your app folder,
Create a new folder inside 'www' root folder and name it xml ,
Paste the config file inside the xml folder and also paste it on www root folder.
Zip the www folder
Log In to phonegap build section link [https://build.phonegap.com/apps] You will see Welcome to Adobe PhoneGap Build
Click Private tab and upload your www zip file
Click Ready to build button
Then click android/iOS/windows Icon to download the file (mine was apk file). download and install the apk file and check you app. Boom!!!
