Creating Android Apps is hard . . .

Why HTML5?
11
HTML5 is the language of the web!
 Flexible, Adaptable
 Used by millions of developers
 HTML5 == HTML5/CSS3/JS

Hybrid HTML5 Apps…
12
…allow developers to build apps using
these skills and tools…
…that can be distributed in native
app stores.

Crosswalk
The advanced web runtime for ambitious HTML5 applications
40

What is Crosswalk
• New HTML5 runtime based on Google’s Blink and Chromium Content Module
• Optimized for Android
• Supports Tizen, Linux, Mac, and Windows
• Open source, BSD licensed. Started in September, 2013
• 6-week release cadence. Stable, Beta and Canary channels
• GitHub for code and reviews. JIRA for features and bugs. FreeNode for IRC.
41

Why do we need a new HTML5 Runtime?
• Deploying on Android is complex
• Multiple type of devices (low cost, high cost)
• Multiple versions of Android (sometimes very old)
• WebView very old, behavior different from one device to the other
• Google focus on the browser, need for a product tailored for app developers
• Based on Blink, the most competitive HTML5 engine
• Many other companies and communities have made the same conclusion and
moved to Blink
42

Crosswalk Project Goals
44
• Enable latest, advanced web application features across all Android devices
• Based on W3C standards and landing zone for new draft APIs and Intel
differentiation, such as SIMD and Presentation API
• Bring web applications to the next level, closer to native
• Easy adaptation for downstream projects
• Integrated with Cordova, Intel® XDK or even existing Android Java applications.
• Good co-operation with upstream projects
• Chromium, Blink, Skia, V8, Wayland
• Fully open source project – embraces participation

Crosswalk Architecture Goals
• Based on Blink and selected parts of Chromium
• Work with upstream to enable features we need
• Minimize the changes on Crosswalk Blink and Chromium
• Crosswalk rapid release cycle always updated with the latest Chromium
version.
• API extensions in separate repositories
• Cordova APIs, early or experimental W3C APIs

Embedding Crosswalk in your Android app
3 easy steps:
1. Download Crosswalk
2. Package Crosswalk with your application using make_apk.py:
$ python make_apk.py --package=org.abc.myapp
• Bundles Crosswalk runtime with your application
• Creates apk for both x86 and arm
3. Install
--manifest=myapp/manifest.json
$ adb install -r myapp_x86.apk

The Crosswalk Advantage
• Advanced web runtime and webview features available for legacy Android platforms
• Application consistency across all Android versions
• Extendable
• Full control over upgrade cycle
• Based on Blink and Chromium
• Latest innovations, strong performance
• Intel is driving innovation in Blink and Chromium, including reviewing and owning various areas of
the code base
• Wide community adoption
• Strong corporate backing
• Open source
