ACTIONSCRIPT 3.0 DEVELOPER’S GUIDE
Displaying HTML content in mobile apps
The loadURL() method loads a resource at the specified URL. You can use any URI scheme supported by the system
web browser control, including: data:, file:, http:, https:, and javascript:. The app: and app-storage: schemes are not
supported. AIR does not validate the URL string.
The loadString() method loads a literal string containing HTML content. The location of a page loaded with this
method is expressed as:
On Desktop: about:blank
On iOS: htmlString
On Android: the data URI format of the encoded htmlString
The URI scheme determines the rules for loading embedded content or data.
Note: If the stage’s displayState property is set to FULL_SCREEN, in Desktop, you cannot type in a text field displayed
in the StageWebView. However, in iOS and Android, you can type in a text field on StageWebView even if the stage’s
displayState is FULL_SCREEN.
The following example uses a StageWebView object to display Adobe’s website:
package {
import flash.display.MovieClip;
import flash.media.StageWebView;
import flash.geom.Rectangle;
}
URI scheme Load local resource Load remote
resource
public class StageWebViewExample extends MovieClip{
}
var webView:StageWebView = new StageWebView();
public function StageWebViewExample() {
webView.stage = this.stage;
webView.viewPort = new Rectangle( 0, 0, stage.stageWidth, stage.stageHeight );
webView.loadURL( "http://www.adobe.com" );
}
On Android devices, you must specify the Android INTERNET permission in order for the app to successfully load
remote resources.
In Android 3.0+, an application must enable hardware acceleration in the Android manifestAdditions element of the
AIR application descriptor to display plug-in content in a StageWebView object. See Enabling Flash Player and other
plug-ins in a StageWebView object.
