Crosswalk on Android can support packaging with XDK and Cordova and SysApps.
- XDK
- PhoneGap
- SysApps
| Embedded mode | Shared mode | |
|---|---|---|
| General introduction | All are packaged together, including crosswalk runtime and web app. It’s intuitive and preferred by users. | Crosswalk runtime is a web engine with rich features so it’s somewhat big(binary >16M). Shared mode provides one shared binary and a wrapper to call the shared binary. Each web app APK is small because it only includes the resources of web app. Note that the share mode only means sharing crosswalk binary between web apps but not running instances. |
| Advantages | ||
| Disadvantages | ||
| Release targets |
Web App APK: HTML/JS/CSS + Android manifest, resources + Java wrapper(calling crosswalk runtime)
Runtime library APK: Crosswalk Runtime -> Crosswalk Runtime Core -> Content API -> Blink
- The reasons to partition this to several components are:
- Hide the details of its based on components.
- Track each component's quality easily via unit tests and Test shell(APKs used to test the functionalities of the component).
- Provide the whole runtime as a 'library'.
- Isolate them for clear understanding and tracking.
- Web App APK
- APK wrapper by calling runtime Java API
- HTML/JavaScript/CSS files
- Generated from APK template
- Runtime is shared by each web application via library sharing
- Runtime
- Runtime Java API, which is simple and easy to use
- API extension infrastructure
- App life cycle, SysApps, Intel API, System Info, UI controls,windowing
- Misc other features
- Generate the runtime as a 'library' APK for Android
- Runtime Core
- An abstraction layer to provide Java classes to runtime and hide the internals of Content and Blink
- Java classes only internally used by Runtime
- Mainly customize and implement Content API by meeting requirements of runtime
- Blink and Content
- Provide HTML5 API, such as WebGL, WebRTC, WebAudio
- Parallel JavaScript, WiDi, etc.
- Performance improvement
