Exploring PhoneGap / Cordova for Mobile App Development

BS Kavya Rao
Posted 9/3/14


Mobile App development  is crucial in this era of smartphones. Many websites now have mobile app equivalents. Since there are so many different platforms that you need to create a mobile app for, it becomes a headache for the developers to create native apps for all the platforms. How amazing would it be if you can just code just once and deploy it on all the platforms- Android, IOS, Windows, Blackberry, etc.? You can- with Phonegap (produced by Nitobi and later purchased by Adobe Systems in 2011). PhoneGap seeks to bridge the gap between mobile app platforms.


PhoneGap is an open source framework for quickly building cross-platform mobile apps using HTML5, Javascript and CSS ,avoiding each mobile platforms' native development language. As simple as that.

 It extends the features of HTML and Javascript to work with the device. The resulting applications are hybrid, meaning that they are neither truly native (as all layout rendering is done via web views instead of the platform's native UI framework) nor purely web-based (as they are not just web apps, but are packaged as apps for distribution and have access to native device APIs).   

Along with HTML,CSS and JS you can also use some mobile frameworks such as jQuery Mobile, Ionic , Sencha Touch ,AppGyver’s Steroids to help improve the processing speed, screen size, network speed, touch events, etc. 

PhoneGap Or Cordova: What’s In A Name?

In the process of learning about PhoneGap, you’ll encounter the name Cordova. Simply put, Cordova is the open-source project that is the basis of PhoneGap. Think of it as the engine that drives PhoneGap.

With “PhoneGap” already being trademarked, a new name was needed when the project was open-sourced hence, "Cordova". “PhoneGap” continues to be used by Adobe for commercial products. Most people still refer to the project as a whole as PhoneGap.

Important Components:

Phonegap app has 3 basic components:

The application itself is implemented as a web page, named index.html by default, that references whatever CSS, JavaScript, images, media files, or other resources are necessary for it to run. The app executes as a WebView within the native application wrapper, which you distribute to app stores.

Apache Cordova applications rely on a common config.xml file that provides information about the app and specifies parameters affecting how it works, such as whether it responds to orientation shifts. 

plugin interface is available for Cordova and native components to communicate with each other. This enables you to invoke native code from JavaScript. As of version 3.0, plugins provide bindings to standard device APIs. Third-party plugins provide additional bindings to features not necessarily available on all platforms.

Ways to create a mobile app with Phonegap:

Cross-platform workflow:

Use this workflow if you want your app to run on as many different mobile OS' as possible at once, with little need for platform-specific development.


 This workflow centers around the cordova utility, otherwise known as the Cordova CLI(Command-Line-Interface),introduced with Cordova 3.0.The CLI copies a common set of web assets into subdirectories for each mobile platform, makes any necessary configuration changes for each, runs build scripts to generate application binaries.

Platform-centered workflow: Use this if you want to build an app for a specific platform with lower level modifications. You need to use this approach for example, if you want your app to mix custom native components with web-based Cordova components.

Platforms supported(for CLI):

  • IOS (Mac)
  • Amazon Fire OS (Mac, Linux, Windows)
  • Android (Mac, Linux, Windows)
  • BlackBerry 10 (Mac, Linux, Windows)
  • Windows Phone 7 (Windows)
  • Windows Phone 8 (Windows)
  • Windows 8 (Windows)
  • Firefox OS (Mac, Linux, Windows)

On theMac, the command-line is available via the Terminal application. On the PC, it's available as Command Prompt under Accessories.

PhoneGap installation:

To Install, ensure that you have NodeJS installed, then open your command line and run the 


C:\> npm install -g phonegap or C:\>npm install -g cordova

Once installation completes, you can invoke phonegap on command line like:

$ phonegap create my-app   or $ cordova create my-app com.example MyApp

$ cd my-app or  $ cd my-app

$ phonegap run android or  $ cordova platform add android

PhoneGap High-Level Application Architecture

The architecture differs case-by-case for applications, however most data-driven applications employ the following basic architecture. The PhoneGap application acts as a client for the user to interact with. The PhoneGap client communicates with an application server to receive data. The application server handles business logic and communicates with a back-end data repository. PhoneGap is agnostic of back-end technologies and can work with any application server using standard web protocols.


The client to application server communication can be based upon standard HTTP requests for HTML content, REST-ful XML services, JSON services, or SOAP (or websockets if your OS supports it).  These are the exact same techniques that you would use in a desktop-browser based AJAX application.

The client-side architecture generally uses the single-page application model, where the application logic is inside a single HTML page.  This page is never unloaded from memory.  All data will be displayed by updating the HTML DOM, data is retrieved from the application server using AJAX techniques, and variables are kept in-memory within JavaScript.

Multi-page client-side application architectures are supported, but are not recommended because you lose in-memory variables when loading a separate page.

Features supported by PhoneGap:

Native Vs PhoneGap :

Before you make a decision on which path to follow let's have a look at the pros and cons of Native and Phonegap applications.

Native Applications:

Since native applications are developed using API's provided by device OS itself, these applications can seamlessly use all possible features of the device. Also, programmers can easily control the level of user experience without compromising on any principal aspects of the application such as performance, battery drain, etc. It is also easy to do code enhancements for these applications.

But, on the other hand, native applications could be programmed only with the specific application development language, such as objective-C for iOS and Java for Android, that the device OS APIs support. Along with investment on high-skilled programmers specialized in the respective application development languages, programming native applications for iOS also requires an addition investment on development-infrastructure, because native applications for iOS could be developed only using Mac machines.

Phonegap applications:

PhoneGap is a free and Open Source framework that enables building hybrid applications which work on almost all the renowned mobile platforms.

PhoneGap framework provides a container that abridges the native APIs to the web view. Hence, web-based mobile applications that have minimal dependencies on the native device capabilities could be developed using PhoneGap framework.

Since development using PhoneGap framework could be done using common web technologies such as HTML, CSS and JavaScript, and the same application could work cross-platform, the application development cost for multiple mobile OS is very less compared to the application development in the native way.

Although PhoneGap framework seems to provide some jaw-dropping advantages on cost, time and effort- with the current generation of release, it has some importent concerns to be addressed yet.

  • Graphic-intensive UI can't be build using Phonegap, so highly animated games go right out the window
  • Application performance, compared to Native apps, needs to be improved
  •  Compared to iOS and Android, PhoneGap lacks strong document support for programmers

Since Phonegap version3.0,  the apps using PhoneGap have become a little faster compared to previous versions.

In a battle of Phonegap Vs Native code, you should really use native if performance requires it.  So, really you should go native for games and hardware intensive apps.

However, if  your app is primarily an information app (or social media or whatever) without a lot of intensive use of hardware, Phonegap would be an ideal choice.

PhoneGap Build:

Even though PhoneGap provides an intuitive and friendly way to create mobile applications, maintaining mobile development environment is still a hassle.

Each vendor provides a different toolchain, and each PhoneGap release is compatible with a specific set of tools. This is where PhoneGap Build comes into help.

PhoneGap Build is a cloud service for compiling PhoneGap applications.

Benifits PhoneGap Build provides:

  • Managed Compilation and Signing
