AC Mobile Build & PhoneGap
There are three ways of building your Apps
AC Mobile Build let's you manage Native App creation directly from Application Craft. AC Mobile Build can be used for Apps built within the Application Craft platform as well as HTML5+CSS+JS Apps built externally.
PhoneGap:Build support is for those developers who have built their Apps within the Application Craft platform but want to built their Apps using Adobe's PhoneGap:Build platform.
PhoneGap Direct assumes you want to build your Apps using tools like Apple's XCode or Eclipse for Android Apps. This is more involved than the other approaches but can give you more control should you need it.
If need to access to device features such as GPS, Accelerometer, Camera, Compass, File System, Storage, Audio, Contacts, then you need to access PhoneGap functions. See here for more information.
