If you are a C/C++ developer and want to develop your own runtime built with Crosswalk, reference Crosswalk Build Instructions for instructions on how to build your own binary.

Downloads

For official binaries, see Downloads. If you would like a binary for an operating system not provided, you will need to build Crosswalk yourself.

Once you have the binaries built, you can follow these instructions.

Install Crosswalk

On Windows

On Windows, the zip package contains:

  • Crosswalk launcher - xwalk.exe (~33M)
  • Crosswalk packaged resources - xwalk.pak (~5M)
  • Unicode and i18n support library - icudt.dll (~9M)
  • EGL/OpenGLES support libraries - libEGL.dll, libGLESv2.dll (~1M)
  • Installer creation script (.bat or .sh)

For a quick 'smoke test', unzip the file into a directory and try to run:

xwalk.exe http://www.google.com

You should see a native app window that renders the www.google.com page. Reference Crosswalk Command Line Options to see which options are provided by this early binary.

On Linux

  1. Download the binary for your platform from the URL in Get Crosswalk.

  2. Unpack the zip file.

  3. Move to the unzipped directory: cd xwalk-linux

  4. Smoke test with a known URL, e.g. ./xwalk http://google.com/

On Android

See Installing Crosswalk. If you are running Android within the x86 emulator, be aware that depending on the capabilities of your host platform's graphics card, you may experience rendering and graphical issues.

On Tizen

See Installing Crosswalk.

Package Your Web App

Given a web app written in HTML5 and Javascript with an index.html entry page, the Crosswalk tools allows you to package it into a native app installer.

You can also pack a manifest.json file with your application. Reference Crosswalk manifest to see how to write a manifest file.

For Windows Installer

The create_windows_installer.bat contained in the Crosswalk binaries is used to package a web app into a native app installer.

A prerequisite for this installer is the Wix toolset. Download the toolset from http://wixtoolset.org/.

Run create_windows_installer.bat --help for instructions on how to use Wix.

usage: create_windows_installer.bat [options] [app_path]

The following options are supported:

app_path                Path to your Crosswalk application. If not specified, the
                          current directory is used.
--wix_bin_path=<path>   Path to Wix toolset binaries. If not specified, the
                          script will try to find them through PATH
--xwalk_path=<path>     Path to Crosswalk binaries. If not specified, the script
                          will try to find them through PATH, the app path, or
                          the current directory.
--app_name=<name>       Name of the application. If not specified, the name
                          of the application directory is used.
--version=<version>     The version of the application, defaults to 1.0.0
--app_arguments=<args>  Arguments that will be passed into Crosswalk executable.
                          If not specified, "index.html" is used. For example,
                          "--allow-file-access-from-files [INSTALLDIR]src/index.html"
--out=<pathname>        File Path of the output installer file, defaults to the
                          current directory with %app_name%.msi as its name.
--publisher=<name>      The manufacturer of this application, defaults to "Me"
--help                  Print this message
Example Usage
  create_windows_installer.bat webapps-scientific-calculator-master --wix_bin_path="C:\Program Files (x86)\WiX Toolset v3.7\bin" --xwalk_path="C:\Users\username\Desktop\xwalk paking\xwalk-win32"

For Linux Installer

The create_linux_installer.sh contained is used to create native installer in RPM or DEB package format through checkinstall utility. You MUST install checkinstall firstly. Run sudo apt-get install checkinstall on Linux system.

The usage is similar with that on Windows, but without Wix:

usage: create_linux_installer.sh [options] [app_path]

This script is used to create a standalone installer for web app. It
depends on checkinstall and crosswalk to function properly.
The following options are supported:

     app_path                Path to your web application. If not specified, the
                               current directory is used.
     --xwalk_path=<path>     Path to Crosswalk binaries. If not specified, the script
                               will try to find them through PATH, the app path, or
                               the current directory.
     --app_name=<name>       Name of the application. If not specified, the name
                               of the application directory is used.
     --version=<version>     The version of the application, defaults to 1.0.0
     --app_index=<path>      Path of app index file, relative to app_path. If not
                               specified, index.html is used.
     --out=<path>            Path of the output package file, defaults to
                               /tmp/xwalk_build/<app_name>
     --publisher=<name>      The manufacturer of this application, defaults to Me
     --help                  Print this message

For Android APK Packaging

The Android APK packaging tool is included with the xwalk-android download. It can work on Linux, Windows and Mac OSX. For setting up the environment for Windows, please see the section 'Windows environment setup'.

To package a web application, unpack the tarball xwalk_app_template.tar.gz which can be gotten from crosswalk-*-[x86, arm].zip:

host$ tar xzvf xwalk_app_template.tar.gz
host$ cd xwalk_app_template

This template contains utilities and dependencies for packaging an application into an Android APK file.

make_apk.py is the key script for packaging a web app as an APK.

Note: To make it work, you should ensure that the android command from the Android SDK and java from Oracle JDK(version 1.6) are included in your PATH. It is located in <Android SDK location>/tools/android.

Here is the help information for the make_apk.py script:

                        is unspecified, all of available platform apks will be
                        generated.

Important: Crosswalk provides the embedded mode and the shared mode in the APK packaging tool as described in Crosswalk on Android.

Package a local web app(all files of a web app are stored in local disk):

Assume that the files for one web app are located under the directory /home/abc/dist and the main entry point HTML file is /home/abc/dist/index.html:

host$ python make_apk.py --package=com.abc.app --name=ABC \
  --app-root=/home/abc/dist --app-local-path=index.html --mode=embedded

An Android APK file called 'ABC-x86.apk' will be generated if running with the packaging tool for X86 version. If the packaging tool is for ARM architecture, the APK file called 'ABC-arm.apk' will be generated. Crosswalk will combine X86 and ARM into one packaging tool in future.

For the shared mode, do it like below:

host$ python make_apk.py --package=com.abc.app --name=ABC \
  --app-root=/home/abc/dist --app-local-path=index.html --mode=shared

An Android APK file called 'ABC.apk' will be generated. It's architecture-independent which means it can work on IA and ARM devices.

Package a host web app(remote web site for example):

Below is one example to package a host web app:

host$ python make_apk.py --package=com.example.app --name=Test1 \
  --app-url=https://www.crosswalk-project.org --mode=[embedded|shared]

The Android APK will be generated as well like packaging local web apps.

Install the generated APK for the embedded mode on an Android IA device (users can install ABC-arm.apk on an Android ARM device as well):

host$ adb install -r ABC-x86.apk

For the shared mode, make sure XWalkRuntimeLib.apk(architecture dependent) has been installed on the Android device firstly. And install the web app APK like below:

host$ adb install -r ABC.apk
Windows environment setup
  1. Install the Android SDK. Make sure to add “%SDK_PATH%\platform-tools” and “%SDK_PATH%\platform-tools\tools” into the "PATH" environment variable.

  2. Update to the latest Android API level.

  3. Install python and ant. Add the installed path of python and the bin path of ant are added into the "PATH" environment variable as well.

  4. Install Oracle JDK and add the paths of “%JAVA_HOME%/bin” and “%JAVA_HOME%/jre/bin” into "PATH". Make sure 'where java' is the path you've set with Oracle JDK. This is very IMPORTANT. The version 1.6.x is preferred.

Note: The Android APK maker works much slower on Windows than Linux and Mac because it takes a so long time to search executives on Windows.

Debug Your Web App

Crosswalk also enables remote debugging to a separate instance of a Chrome browser.

  • Step 1: Install Google's Chrome browser from www.google.com/chrome/‎,
  • Step 2: Launch Crosswalk with remote debugging option xwalk.exe --remote-debugging-port=9222 index.html
  • Step 3: Open localhost:9222 in the Chrome browser, and you will see the inspectable pages in Chrome tab.
  • Step 4: Click the inspectable page to open the Web Inspector UI to start debugging.

Known Issues

  • Network proxy set by environment doesn't take effect on Linux. Instead, you have to set the system wide network proxy.
  • Cannot play HTML5 video. It is because the ffmpeg library is not included in the Crosswalk binaries. Set Tips#1 for using ffmpeg to play HTML5 video in Crosswalk.
  • CSS3D and WebGL can not work on Windows if DirectX End-User Runtime is not installed on your system. Go to here to install DirectX End-User Runtime on your system.
