Content overview

When to Use

ArkWeb provides Web components to display web page content in applications. You can use the components in the following scenarios:

  • Web page integration: Applications can use Web components to embed web page content to reduce development costs and improve development and O&M efficiency.

  • Web browsing: Browser applications can use Web components to open third-party web pages, browse web pages in traceless mode, and set advertisement blocking.

  • Applet: Host applications of applets can use Web components to render the pages of the applets, implement same-layer rendering, and take over video playback.

Available Capabilities

The Web component provides various capabilities for you to control web pages, including:

  • Web page loading: declarative loading and off-screen loading of web pages.

  • Lifecycle management: component lifecycle status change and web page loading status change notification.

  • Common attributes and events: management of user agent, cookie and storage, font and dark mode, and permission.

  • Interaction with the application UI: The custom text selection menu, context menu, and file upload page can interact with the application UI.

  • Interaction between applications and web pages through JavaScriptProxy.

  • Security and privacy: traceless browsing mode, advertisement blocking, and Secure Shield mode.

  • Maintenance and debugging capability: DevTools for debugging, crashpad for collecting crash information of the Web component, use Hypium to implement ArkWeb automated testing, and troubleshooting white screen issues on web pages.

  • Other advanced capabilities: same-layer rendering with system components, network and media playback takeovers, add password vault for web pages, and custom input method for Web component text boxes.

Required Permissions

The ohos.permission.INTERNET permission is required for accessing online web pages. For details about how to apply for a permission, see Declaring Permissions.
