Android/PhoneGap

What is PhoneGap?

PhoneGap allows programmers to build applications for Android and other mobile devices in JavaScript, HTML5, and CSS3. PhoneGap (also called Apache Cordova) is open source software.

As of cordova-android@4.0.0, Apache Cordova has switched to Android Studio and Gradle, and switched away from Eclipse and Ant.

Following the Phonegap documention,^[3]^[4]

These first few steps set up the standard Java development environment for Android:

Download and install Android SDK
Download and install the ADT plugin

The next steps add Apache Cordova, setting up a standard JavaScript HTML CSS development environment for Android:

Download the latest copy of Cordova and extract its contents.
Setup your PATH environment variable

Plugins

Many plugins have been developed for PhoneGap.^[5]^[6]

One popular plugin is the Barcode plugin.

Barcode plugin

(This section describes how to scan a barcode inside a PhoneGap app. An alternate approach scans a barcode from a normal HTML/JavaScript Web page.^[7])

Several people use the Barcode plugin to work with barcodes in their PhoneGap application.^[8] ^[9] ^[10] ^[11] ^[12] ^[13]

The standard PhoneGap barcode plugin is often all an Android application needs. If it doesn't yet support the barcode format you want to use, you may need to build your own custom PhoneGap plugin, perhaps starting with Barcode development in Java.^[14]
