Intro
The following brief guide assumes you have Node.js, NPM, and Git installed and
working correctly on your local system. Then, you'll need to ensure you have the latest
version of Cordova installed and working correctly.

Check Cordova requirements
These checks and requirements are per platform, for example for development with
Android.
Initially, we can check required and installed dependencies for Cordova with the following
command,
cordova requirements

This command will check build requirements for each install platform, e.g. Android.

Android requirements and environment setup
Before installing and conﬁguring Android, we need to ensure that the latest version of the
Java SDK is available,
update java to latest se version, e.g. 1.8.0_102
update ~/.bash_profile
# Create a JAVA_HOME variable, location determined dynamically as part of install
export JAVA_HOME=$(/usr/libexec/java_home)
# Add that to the global PATH variable

export PATH=${JAVA_HOME}/bin:$PATH

n.b. this will add Java path &c. for latest Java version...
Then, we can start to setup our Android environment,
download Android Studio
install and follow prompts for default install and setup
if installing just the Android SDK, add the directory location of the SDK's tools and
platform-tools to PATH

e.g.
add ANDROID_HOME to path in ~/.bash_profile
export ANDROID_HOME=~/Development/android-sdk/
export PATH=$PATH:~/Development/android-sdk/platform-tools/
export PATH=$PATH:~/Development/android-sdk/tools/
export PATH=$PATH:~/Development/android-sdk/build-tools/

then setup an Android Virtual Device (AVD) for use as an emulator
follow guide at https://developer.android.com/studio/run/managing-avds.html
open Android Studio
select option for AVD manager from toolbar for open project (normally 4th from
the right)
follow prompts and choose preferred speciﬁc device or generic device type
choose required Android platform, e.g. Android 6.0, SDK 23
Or, we can issue the following command to use the AVD manager directly
android avd

However, latest AVD deﬁnitions (incl. Nexus 5x, 6P...) are available using AVD manager via
Android Studio 2.1.

Create basic app
To test the new Cordova install, we can now create a simple initial app
cordova create test com.example.test TestApp

This command will create a new app with its own basic, shell template for the app's
underlying structure. The home page for this app will be stored in www/index.html.

Add Android platform

For a chosen project, we can then add required platforms for our application. These are
the mobile OSs the app needs to run on, and Cordova will support. We can add the
Android platform with the following command from within the root directory of our
Cordova app,
cordova platform add android --save

We can then check all current install platforms with the following command,
cordova platform ls

Each platform added to a project is stored in the app's /platforms/ directory. These
ﬁles are maintained and updated as part of the build and update process run by Cordova
for the current app.

Build basic app
After creating our basic test app, we can now build it from the directory created for the
app.
cordova build

This command will build the current app for the installed platforms. However, we may also
wish to limit the scope of a given build to a speciﬁc platform, e.g.
cordova build android

Emulate app
We can also build our app, and then open it for testing with an installed emulator
cordova emulate android

This will choose the default installed emulator for the chosen platform. However, we may
also wish to add a ﬂag for a speciﬁc emulated device,
cordova emulate android --target=Nexus_6P_API_23

This will load the app in the speciﬁc emulator for the Nexus 6P.
Example app loaded in emulator,
