First developed at an iPhoneDevCamp event in San Francisco, PhoneGap went on to win the People’s Choice Award at O’Reilly Media‘s 2009 Web 2.0 Conference and the framework has been used to develop many apps. Apple Inc. has confirmed that the framework has its approval, even with the new 4.0 developer license agreement changes. The PhoneGap framework is used by several mobile application platforms such as ViziApps, Worklight, Convertigo and appMobi as the backbone of their mobile client development engine. Adobe officially announced the acquisition of Nitobi Software (the original developer) on October 4, 2011. Coincident with that, the PhoneGap code was contributed to the Apache Software Foundation to start a new project called Apache Cordova. The project original name, Apache Callback, was viewed as too generic. Then it also appears in Adobe Systems as Adobe PhoneGap and also as Adobe Phonegap Build (now out of beta).
Early versions of PhoneGap required a person making iOS apps to have an Apple computer, and a person making Windows Mobile apps to have a computer running Windows. After September 2012, the “PhoneGap Build” service allows a programmer to upload his source code to a “cloud compiler” that generates apps for every supported platform.
W3C Geolocation API
The W3C Geolocation API is an effort by the World Wide Web Consortium (W3C) to standardize an interface to retrieve the geographical location information for a client-side device. It defines a set of objects, ECMAScript standard compliant, that executing in the client application give the client’s device location through the consulting of Location Information Servers, which are transparent for the application programming interface (API). The most common sources of location information are IP address, Wi-Fi and Bluetooth MAC address, radio-frequency identification (RFID), Wi-Fi connection location, or device Global Positioning System (GPS) and GSM/CDMA cell IDs. The location is returned with a given accuracy depending on the best location information source available.
