This very simple example demonstrates initialising the extension and the advertising platform and then displaying an advert aligned to the bottom centre.

distriqt.extension.adverts.example.as

if (Adverts.isSupported)
{
	Adverts.service.initialisePlatform( AdvertPlatform.PLATFORM_ADMOB );

	var adView:AdView = Adverts.service.createAdView();
	adView.setAdSize( AdSize.SMART_BANNER );
	adView.setAdUnitId( AD_UNIT_ID );
	adView.setViewParams( new AdViewParamsBuilder()
		.setVerticalAlign( AdViewParams.ALIGN_BOTTOM )
		.setHorizontalAlign( AdViewParams.ALIGN_CENTER )
		.build()
	);
	adView.load( new AdRequestBuilder().build() );
	adView.show();
}
