Google Mobile Ads SDK 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.
Usage
To specify a creative type, include theft_ctypeparameter in an extras object
and pass it to the ad request. This may restrict which ads are available and
result in no fill.
The following table lists the valid values forft_ctype:
Creative Type

Banner, Interstitial, Rewarded
App install image
image_app_install

This feature impacts Google ads only. If your ad unit enablesmediation, ads returned from third-party ad sources don't
respect theft_ctypeparameter. We recommend testing with an ad unit that
doesn't have mediation enabled.
