PhoneGap plugin contains two files :
* JavaScript file that defines the function for accessing the native hooks
* Implementation files written in the native language to co-ordinate with native phone features
To create your own PhoneGap plugins, you have to :
* Make a new directory in your ${PROJECT_DIR}/plugins directory
* Make a JavaScript file within that new directory
* Make a new Objective-C class that extends the PhoneGap command class and also in the new directory
