Dialog web

A decision block that lets the user view a web or HTML page.

The fiber will pause until the user has dismissed the dialog, a page redirected to the intercepted ok or cancel page URL or the timeout expired.

Intercepted page URLs controlling the dialog:

Controlling the dialog OK button:

  • When the regular expression match the URL of the loaded page then it’s enabled, i.e. use .* for always, otherwise it’s disabled.
  • In an HTML page it can be enabled using JavaScript automate.setOkButtonEnabled(true); (Android 4.2+)
  • Clicks on it can be ignored, preventing the dialog from closing, by cancelling the custom automate.ok window event using JavaScript, e.g. window.addEventListener("automate.ok", e => e.preventDefault()); (Android 4.4+)

Browser console messages, e.g. JavaScript errors, are logged to the system log when the Debug logging option is enabled in settings. Use the Log await block, logcat shell command or other “log viewing” app to view.

The Viewport argument affects how the content is laid out and scaled.

Usage examples

  • Display a run-time generated HTML page by passing it as the HTML page argument.
  • Browse the web by passing a regular http:// or https:// URL as the page URL argument.
  • Display local content, such as HTML, image, video, PDF, by passing an file:// or content:// URI as the page URL argument.
  • Create an (OAuth2) authentication flow for Google, Facebook, etc., to acquire an authentication token for accessing their online APIs using HTTP requests.
  • Display a custom interactive layout drawn using JavaScript.

Note! Ensure to enable the appropriate allowed flags otherwise the page will fail to load. Loading content URIs created by the fileUri, i.e with no or "a" flag, require both File access and Content access.
