Develop ads for the Google Mobile Ads SDK

MRAID compatibility

The Google Mobile Ads SDK supports the IAB's Mobile Rich Media Ad Interface Definitions (MRAID) standard for advertising in mobile apps. You can set a line item as MRAID v1 or MRAID v2 through the line item targeting settings, under Devices > Device capability.

MRAID v2 requires Google Play services v7.8 or higher for Android and Google Mobile Ads SDK v7.4.0 or higher for iOS. To use MRAID functions in your ad creatives, you must import mraid.js into your creative. To do this, include <script src="mraid.js"> in your creative. The Google Mobile Ads SDK, as an MRAID-compatible SDK, will look for that code in the creative and replace it with an actual URL pointing to an implementation of MRAID. Other SDKs that support MRAID will do the same though their actual URLs would be different. You can optionally include the MRAID libraries, as well as the Google Mobile Ads SDK functionality, in the same creative.

mraid.resize() and other similar functions won't have any effect until after the ad is clicked. This prevents a malicious creative from automatically resizing and taking up the entire screen.

Learn more about MRAID support in the developer documentation.

Google Mobile Ads SDK functionality

To take advantage of the functionality of the Google Mobile Ads SDK, you can use the JavaScript functions exposed by the google.mobile.app.ads class. You must include the following code in the <head> section of the creative:

Access to device capabilities

The SDK also exposes the capabilities of the in-app browsers available on iOS and Android. This allows developers to access device capabilities such as the accelerometer, gyroscope and compass via HTML5 where the platform supports them. Please refer to the documentation for each platform for more information on these capabilities and how to access them.

App events

App events (3:16)

App events enable you to execute custom code in your application when a creative dispatches an app event. With app events, you can introduce custom ad executions that interact with the application, such as changing the background color of the app.

Learn how to implement app events.

Scaling image to full screen

If you find that your full screen ad is only taking up part of the screen, insert the following code in the <head> section of the creative:

<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no"/>.

Sample code for a rotatable ad

You can use the code below to serve a rotatable ad.

<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=0">

Non-MRAID example, using creative templates

You can use the sample code below to serve a banner to a mobile application. On click, the banner expands to a full-screen unit displayed in an overlay window inside the application. In the sample code, replace the following placeholder elements with your own values:

[FALLBACK_CLICKURL]: Backup landing page in case JavaScript function doesn't get called.
[FULLSCREEN_UNIT]: URL of full screen ad unit.
[ORIENTATION]: Supported orientation for full screen unit (use "p" for portrait, "l" for landscape, or omit this value to allow any orientation).
[BANNER_UNIT]: URL of banner image.
[WIDTH]: Width of banner.
[HEIGHT]: Height of banner.

Sample code for automatically closing an interstitial

Only directly-booked interstitials can be automatically closed; interstitials served via dynamic allocation (i.e., Ad Exchange, AdSense or AdMob) can only be dismissed by the user.

To make an interstitial close after a fixed period of time:

Include code in the creative to close the interstitial after a fixed period of time has elapsed. The following code can be used as a template for this approach:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"/>
      <script type="text/javascript" src="https://media.admob.com/api/v1/google_mobile_app_ads.js"></script>
      <script>
        <!--
          function
          _admStartCountDown(){setTimeout('admob.opener.close()',parseInt('[%displayTime%]')*1000)}
          function
          _admOnload(){if(admob.opener.isOverlayShowing()){_admStartCountDown()}else{admob.events.addEventListener('onshow',
          _admStartCountDown)}}
          if(window.addEventListener){window.addEventListener("load",_admOnload,false)}else{window.attachEvent("onload",_admOnload)}
        //-->
      </script>
  </head>
  <body>
    [Your_AdCode_Goes_Here]
  </body>
</html>

Target window: in-app overlay window

Using admob.opener.openOverlay(), you can open a full screen overlay browser that is animated from the bottom of the screen. This browser does not include a status bar and always displays a close button at the upper-left corner. This option can work nicely for an expandable ad where the full screen unit can be hosted on a separate page (see the sample code for an expandable ad).

Below is sample code for a simple banner where the full screen unit can be loaded into an overlay browser window. You should replace the following placeholder elements with your own values. If available for your network, you can use the sample code to create a creative template.

[BANNER_UNIT]: URL of a banner creative.
[WIDTH]: Width of a banner creative.
[HEIGHT]: Height of a banner creative.
[FULLSCREEN_UNIT]: URL of a full screen creative. Note: Full screen unit should include JavaScript code to parse the destination URL and redirect the user to the landing page upon receiving a click action. See Handling destination URL from a full screen unit for more details.
[DESTINATION_URL]: URL of a destination page.
[FALLBACK_URL]: Fallback destination URL to use in case JavaScript function doesn't execute.
[ORIENTATION]: Supported orientation for destination URL (use "p" for portrait, "l" for landscape, or omit this value to allow any orientation).

Here's a sample creative code:

<!DOCTYPE html>
<head>
<meta name="viewport" 
content="user-scalable=no, width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"/>

<script type="text/javascript" src="https://media.admob.com/api/v1/google_mobile_app_ads.js"></script>
</head>

<body>
<a href="[FALLBACK_CLICKURL]" 
onClick="admob.opener.openOverlay('%%CLICK_URL_ESC%%[FULLSCREEN_UNIT]?destination=[DESTINATION_URL]', 
'[ORIENTATION]'); return false;"><img border="0" 
src="[BANNER_UNIT]" width="[WIDTH]" height="[HEIGHT]"></a>
</body>
</html>

Handling destination URL from a full screen unit

The admob.opener.openOverlay() function does not have the option to specify the destination URL of the html content. Assuming that you've passed the destination URL in the form of key-value pair when specifying the fullscreen unit, e.g. "https://link.to.fullscreen.unit?destination=https://my.destination.url", you can write a simple JavaScript function and include a snippet of HTML code to capture the click and redirect the user to the destination page.

Here's a sample page source:

<!DOCTYPE html>
<head>
<meta name="viewport" 
content="user-scalable=no, width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"/>

<script type="text/javascript" src="https://media.admob.com/api/v1/google_mobile_app_ads.js"></script>

<script type="text/javascript">
function destinationUrl() {
  // Get current url after ?
  var destinationUrl = window.location.search;

  // Strip off the leading '?'
  destinationUrl = destinationUrl.substring(1);
  // Parse destination=url key-value pair
  var kvPair = destinationUrl.split("=");
  var key = kvPair[0]; // key: destination
  var value = kvPair[1]; // value: url
  var url = decodeURIComponent(value); 

  // Open destination inside overlay
  window.location = url;

  // Open destination in an external browser
  // admob.opener.openUrl(url, true);
}
</script>
</head>

<body>
<div style="position:relative;">
<!-- Load content source into an iframe -->
<iframe src="https://creative.admob.com/t1/bestBuy/tradeinJul/gi/" 
align="middle" frameborder=0 width=320 height=480 marginheight=0 marginwidth=0 scrolling=no></iframe>
<!-- Create a clickable area -->
<a href="#" onClick="destinationUrl(); return false;" style="position:absolute; top:0; left:0; 
display:inline-block; width:320px; height:480px; z-index:5;"></a>
</div>
</body>
</html>

Target window: new browser window

Using admob.opener.openUrl(), you can open a new native browser window (outside the application). Below is sample code for a simple banner where the destination URL can be loaded into a new browser window. You should replace the following placeholder elements with your own values. If available for your network, you can use the sample code to create a creative template.

[BANNER_UNIT]: URL of a banner creative.
[WIDTH]: Width of a banner creative.
[HEIGHT]: Height of a banner creative.
[FULLSCREEN_UNIT]: URL of a full screen creative.
[FALLBACK_URL]: Fallback destination URL to use in case the JavaScript function doesn’t execute.

Here's a sample creative code:

<!DOCTYPE html>
<head>
<meta name="viewport" 
content="user-scalable=no, width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"/>

<script type="text/javascript" src="https://media.admob.com/api/v1/google_mobile_app_ads.js"></script>
</head>

<body>
<a href="[FALLBACK_CLICKURL]" 
onClick="admob.opener.openUrl('%%CLICK_URL_ESC%%[FULLSCREEN_UNIT]', true); 
return false;"><img border="0" src="[BANNER_UNIT]" width="[WIDTH]" height="[HEIGHT]"></a>
</body>
</html>
