Google Mobile Ads SDK (Legacy) provides an API that lets you specify a creative type for test queries. When the parameter is set, only creatives of the specified type are retrieved and rendered. > [!IMPORTANT] > **Important:** This feature doesn't apply to reservation inventory, which may still serve if not explicitly disabled for the specified slot. We recommend that you test with a backfill-only ad unit. ## Usage To specify a creative type, include the `ft_ctype` parameter in an extras object and pass it to the ad request. This may restrict which ads are available and result in no fill. > [!NOTE] > **Note:** The `ft_ctype` parameter only works in [Test Mode](https://developers.google.com/ad-manager/mobile-ads-sdk/android/test-ads.md.txt#enable_test_devices). ### Kotlin ```kotlin val extras = Bundle() extras.putString("ft_ctype", "video_app_install") val request = AdManagerAdRequest .Builder() .addNetworkExtrasBundle(AdMobAdapter::class.java, extras) .build() ``` ### Java ```java Bundle extras = new Bundle(); extras.putString("ft_ctype", "video_app_install"); AdManagerAdRequest request = new AdManagerAdRequest .Builder() .addNetworkExtrasBundle(AdMobAdapter.class, extras) .build(); ``` The following table lists the valid values for `ft_ctype`: | Creative Type | ft_ctype | Format | |---|---|---| | HTML5 | html5 | Banner, Interstitial, Rewarded | | App install image | image_app_install | Banner, Native, Interstitial, Rewarded | | Display image | image_display | Banner, Interstitial | | Display partial slot | partial_slot | Banner, Native, Interstitial | | App install text | text_app_install | Banner, Native, Interstitial | | Display text | text_display | Banner, Native, Interstitial | | Trueview | trueview | Interstitial, Rewarded | | App install video | video_app_install | Banner, Native, Interstitial, Rewarded | This feature impacts Google ads only. If your ad unit enables [mediation](https://developers.google.com/ad-manager/mobile-ads-sdk/android/mediation.md.txt), ads returned from third-party ad sources don't respect the `ft_ctype` parameter. We recommend testing with an ad unit that doesn't have mediation enabled.
