1. PhoneGap Desktop application.
This will let you easily transfer the application to the mobile device without necessity to compile the application on host computer and transfer the .apk file (in case of Android device).
Install the PhoneGap Desktop application as described here. Download the installer and run it.
2. PhoneGap CLI
Prerequisite is node.js. Download it and install. I will use the latest version, but LTS is always safer. Note, that on different versions of Windows node.js behaves differently. On Windows8 I recall I got a separate console for Node.js. On Windows7 it can be run from a normal Windows console (type cmd in the command search).
Now from console run the following command:
npm install -g phonegap@latest
From now on we can use phonegap command from the command line.
3. Android SDK manager
On windows this comes as a part of Android Studio, though it’s possible to install it separately: http://developer.android.com/sdk/installing/index.html
I will download Android Studio: http://developer.android.com/sdk/index.html and call SDK Manager from the toolbar.
I store my code on Github, so I’ll need Git.
Download the installer here and run it.
When the installer asks about the PATH modification, I prefer to choose the option to allow git to run from command line (third option on the picture below):
