GoogleMobileAds Framework Reference

  • GADDisplayAdMeasurement is used for measuring viewability in display custom native ad formats.

  • It provides a view property to assign the ad view for measurement and a start method to initiate the measurement process.

  • The start method should be called only once and any subsequent calls will have no effect after successful initiation.

  • Viewability measurement relies on the Open Measurement Interface Definition (OMID) framework.
