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 (note: this is fixed in Crosswalk 15)

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. Crosswalk variables can be configured as an option when installing the plugin
• 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 you might have to run cordova clean before building, if you previously built the app without cordova-plugin-crosswalk-webview. Also, manually uninstall the app from the device/emulator before attempting to install the crosswalk-enabled version.

Also 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 by specifying certain variables while installing the plugin, or by changing the value of xwalkVersion in your config.xml after installing the plugin. Some examples:

<!-- These are all equivalent -->
cordova plugin add cordova-plugin-crosswalk-webview --variable XWALK_VERSION="org.xwalk:xwalk_core_library:14+"
cordova plugin add cordova-plugin-crosswalk-webview --variable XWALK_VERSION="xwalk_core_library:14+"
cordova plugin add cordova-plugin-crosswalk-webview --variable XWALK_VERSION="14+"
cordova plugin add cordova-plugin-crosswalk-webview --variable XWALK_VERSION="14"
<preference name="xwalkVersion" value="org.xwalk:xwalk_core_library:14+" />
<preference name="xwalkVersion" value="xwalk_core_library:14+" />
<preference name="xwalkVersion" value="14+" />
<preference name="xwalkVersion" value="14" />

You can also use a Crosswalk beta version. Some examples:

<!-- These are all equivalent -->
cordova plugin add cordova-plugin-crosswalk-webview --variable XWALK_VERSION="org.xwalk:xwalk_core_library_beta:14+"
<preference name="xwalkVersion" value="org.xwalk:xwalk_core_library_beta:14+" />

You can set command-line flags as well:

<!-- This is the default -->
cordova plugin add cordova-plugin-crosswalk-webview --variable XWALK_COMMANDLINE="--disable-pull-to-refresh-effect"
<preference name="xwalkCommandLine" value="--disable-pull-to-refresh-effect" />

You can use the Crosswalk shared mode which allows multiple Crosswalk applications to share one Crosswalk runtime downloaded from the Play Store.

<!-- These are all equivalent -->
cordova plugin add cordova-plugin-crosswalk-webview  --variable XWALK_MODE="shared"
<preference name="xwalkMode" value="shared" />

You can also use a Crosswalk beta version on shared mode, e.g.:

<!-- Using a Crosswalk shared mode beta version -->
cordova plugin add cordova-plugin-crosswalk-webview --variable XWALK_VERSION="org.xwalk:xwalk_shared_library_beta:14+"

You can use the Crosswalk lite mode which is the Crosswalk runtime designed to be as small as possible by removing less common libraries and features and compressing the APK.

<!-- These are all equivalent -->
cordova plugin add cordova-plugin-crosswalk-webview  --variable XWALK_MODE="lite"
<preference name="xwalkMode" value="lite" />

You can set background color with the preference of BackgroundColor.

<!-- Set red background color -->
<preference name="BackgroundColor" value="0xFFFF0000" />

You can also set user agent with the preference of xwalkUserAgent.

<preference name="xwalkUserAgent" value="customer UA" />
