cordova-plugin-crosswalk-webview

Makes your Cordova application use the Crosswalk WebView instead of the System WebView. Requires cordova-android 4.0 or greater.

Benefits

• WebView doesn't change depending on Android version
• Capabilities: such as WebRTC, WebAudio, Web Components
• Performance improvements (compared to older system webviews)

Drawbacks

• Increased memory footprint
  • An overhead of ~30MB (as reported by the RSS column of ps)
• Increased APK size (about 17MB)
• Increased size on disk when installed (about 50MB)
• Crosswalk WebView stores data (IndexedDB, LocalStorage, etc) separately from System WebView
  • You'll need to manually migrate local data when switching between the two

Install

The following directions are for cordova-cli (most people). Alternatively you can use the Android platform scripts workflow.

• Open an existing cordova project, with cordova-android 4.0.0+, and using the latest CLI.
• Add this plugin

$ cordova plugin add cordova-plugin-crosswalk-webview

• Build

$ cordova build android

The build script will automatically fetch the Crosswalk WebView libraries from Crosswalk project download site (https://download.01.org/crosswalk/releases/crosswalk/android/maven2/) and build for both X86 and ARM architectures.

For example, building android with Crosswalk generates:

/path/to/hello/platforms/android/build/outputs/apk/hello-x86-debug.apk
/path/to/hello/platforms/android/build/outputs/apk/hello-armv7-debug.apk

Note that it is also possible to publish a multi-APK application on the Play Store that uses Crosswalk for Pre-L devices, and the (updatable) system webview for L+:

To build Crosswalk-enabled apks, add this plugin and run:

$ cordova build --release

To build System-webview apk, remove this plugin and run:

$ cordova build --release -- --minSdkVersion=21

Configure

You can try out a different Crosswalk version using a <preference> tag within your config.xml. Some examples:

<!-- These are all equivalent -->
<preference name="CROSSWALK_ANDROID_VERSION" value="org.xwalk:xwalk_core_library_beta:13+" />
<preference name="CROSSWALK_ANDROID_VERSION" value="xwalk_core_library_beta:13+" />
<preference name="CROSSWALK_ANDROID_VERSION" value="13+" />
<preference name="CROSSWALK_ANDROID_VERSION" value="13" />

You can set command-line flags as well:

<!-- This is the default -->
<preference name="CROSSWALK_ANDROID_COMMANDLINE" value="--disable-pull-to-refresh-effect" />
