# Windows Phone 8 Platform Guide

This guide shows how to set up your SDK development environment to deploy Cordova apps for Windows Phone devices. It focuses on Windows Phone 8, but provides additional details on how to support Windows Phone 7.

It shows how to use either Windows Phone-specific shell tools to generate and build apps, or the cross-platform Cordova CLI discussed in The Command-Line Interface. (See the Overview for a comparison of these development workflows.) This section also shows how to open Cordova apps so that you can modify them within Visual Studio. Regardless of which approach you take, you need to install the Windows Phone SDK, as described below.

See the following for details specific to the Windows Phone platform:

For the Windows Phone 8 platform, the Cordova WebView relies on Internet Explorer 10 as its rendering engine, so as a practical matter you can use IE10's powerful debugger to test any web content that doesn't invoke Cordova APIs. The Windows Phone Developer Blog provides helpful guidance on how to support IE10 along with comparable WebKit browsers.

## Requirements and Support

You need the following:

• A 64-bit version of Windows 8 Pro, either an installation disk or an ISO disk image file. An evaluation version is available on the Microsoft Developer Network. The Pro version is necessary to run the device emulator.

• In order to deploy via the command-line with the Windows Phone 8.0 SDK, Visual Studio 2012 Update 2 must be installed.

To develop Cordova apps for Windows Phone devices, you may use a PC running Windows, but you may also develop on a Mac, either by running a virtual machine environment or by using Boot Camp to dual-boot a Windows partition. Consult these resources to set up the required Windows development environment on a Mac:

If you are developing on a PC, its processor must support virtualization (VT-x on Intel) and Second Level Address Translation (SLAT). Consult Intel's list of supporting processors. Virtualization is typically disabled by default, so you need to enable it in your BIOS settings. The PC should have at least 6.5GB of free hard disk space, and 4GB of RAM.

## Using Cordova Shell Tools

If you want to use Cordova's Windows Phone-centered shell tools in conjunction with the SDK, you have two basic options:

• Access them locally from project code generated by the CLI. They are available in the platforms/wp8/cordova directory after you add the wp8 platform as described below.

• Download them from a separate distribution at cordova.apache.org. The Cordova distribution contains separate archives for each platform. Be sure to expand the appropriate archive, cordova-wp8\wp8 in this case, within an empty directory. The relevant batch utilities are available in the top-level bin directory. (Consult the README file if necessary for more detailed directions.)

These shell tools allow you to create, build, and run Windows Phone apps. For information on the additional command-line interface that enables plugin features across all platforms, see Using Plugman to Manage Plugins. See Application Plugins for guidance on how to develop plugins, and Windows Phone 8 Plugins for details specific to the Windows Phone platform.

## Install the SDK

Install the latest version of the Windows Phone SDK from the Downloads area of dev.windowsphone.com. You may also install more recent emulator update packages.

## Create a New Project

At this point, to create a new project you can choose between the cross-platform CLI tool described in The Command-Line Interface, or the set of Windows Phone-specific shell tools. From within a source-code directory, here's the CLI approach:

    > cordova create hello com.example.hello HelloWorld
> cd hello


Here's the corresponding lower-level shell-tool approach:

    C:\path\to\cordova-wp8\bin\create.bat C:\path\to\new\hello com.example.hello HelloWorld


## Build the Project

If you are using the CLI in development, the project directory's top-level www directory contains the source files. Run either of these within the project directory to rebuild the app:

    > cordova build
> cordova build wp8   # do not rebuild other platforms


If you are using the Windows Phone-specific shell tools in development, there is a different approach. Once you generate the project, the default app's source is available in the projects\wp8\www subdirectory. Subsequent commands are available in the cordova subdirectory at the same level.

The build command cleans project files and rebuilds the app. The first example generates debugging information, and the second signs the apps for release:

    C:\path\to\project\cordova\build.bat --debug
C:\path\to\project\cordova\build.bat --release


The clean command helps flush out directories in preparation for the next build:

    C:\path\to\project\cordova\clean.bat


## Deploy to Emulator

At this point you can use the cordova CLI utility to deploy the application to the emulator from the command line:

    > cordova emulate wp8


Otherwise use the alternate shell interface:

    C:\path\to\project\cordova\run


By default, the run script invokes the emulator flag, and accepts additional build flags, for which --debug provides the default:

    C:\path\to\project\cordova\run --emulator --debug
C:\path\to\project\cordova\run --emulator --release
C:\path\to\project\cordova\run --emulator --nobuild


The emulator launches a device image with the app installed. From the home screen, navigate to the apps panel to launch the HelloWorld app. This shows the app launching with its splash screen followed by its main interface:

The emulator's basic controls on the top-right of the device screen allow you to toggle between portrait and landscape orientation. The » button opens more controls that allow you to test more complex orientations and gestures:

These advanced controls also allow you to modify the device's location or to simulate sequences of movements:

## Deploy to Device

Before testing your application on a device, the device must be registered. Consult Microsoft's documentation for details on how to deploy and test on Windows Phone 8. Also, make sure the phone is connected to the computer, and the screen is unlocked.

Then run the following CLI command to run the app on the device:

> cordova run wp8


It corresponds to this lower-level shell command:

C:\path\to\project\cordova\run --device


Alternately, if you are working in Visual Studio, select Windows Phone Device from the drop-down menu at the top, then press the green Play button nearby or else type F5.

## Modify the Project in the SDK

Once you build a Cordova app as described above, you can open it with the SDK. The various build commands generates a Visual Studio Solution (.sln) file. Open the file to modify the project within Visual Studio. The web-based source code is available within the project's www directory. Along with other tools the SDK provides, the control below the menu allows you to launch the app in a Windows Phone emulator:

Consult the Overview for advice on how to use Cordova's command-line tools or the SDK in your workflow. The Cordova CLI relies on cross-platform source code that routinely overwrites the platform-specific files used by the SDK. If you want to work within the SDK, use the lower-level shell tools as an alternative to the CLI.
