The IMA SDK must be able to tell when ads are visible to users so that it can
send the correct signals back to the ad server. IMA uses
Active View reporting
to measure the viewability of ads. This guide explains how Active View
reporting works with IMA, as well as how to verify that the SDK is able to
correctly capture viewability signals.
Active View receives measurements on that VideoAdPlayer
(getLocationOnScreen and getGlobalVisibleRect).
Verifying that the SDK can measure ad viewability
To check whether that the SDK is able to capture viewability signals, look for
network requests sent to https://pagead2.googlesyndication.com/pcs/activeview
and check for the mtos parameter. For more information, see
Monitor Active View measurement.
