Cordova android app to xampp database (mysql)

[Yojerry11]

I have made few buttons in the app using html php and javascript and they are working just fine in xampp folder "htdocs" but i want to build them in my android app using phonegap (node.js) and when i tried it, it didn't work in mobile simulator (genymotion) it gives "error" when i click the button! Can anyone help me solve this problem? I will be really grateful for that.
