IMA uses\n[Active View reporting](//support.google.com/admanager/answer/3154105)\nto measure the viewability of ads. This guide explains how Active View\nreporting works with IMA, as well as how to verify that the SDK is able to\ncorrectly capture viewability signals.\n\nHow Active View reporting works with the IMA SDK\n------------------------------------------------\n\n1. The [`StreamDisplayContainer`](/interactive-media-ads/docs/sdks/android/dai/api/reference/com/google/ads/interactivemedia/v3/api/StreamDisplayContainer)\n is created by passing in an instance of\n [`VideoStreamPlayer`](/interactive-media-ads/docs/sdks/android/dai/api/reference/com/google/ads/interactivemedia/v3/api/player/VideoStreamPlayer).\n\n2. Active View receives measurements on that `VideoStreamPlayer`\n (`getLocationOnScreen` and `getGlobalVisibleRect`).\n\nVerifying that the SDK can measure ad viewability\n-------------------------------------------------\n\nTo check whether that the SDK is able to capture viewability signals, look for\nnetwork requests sent to `https://pagead2.googlesyndication.com/pcs/activeview`\nand check for the `mtos` parameter. For more information, see\n[Monitor Active View measurement](//support.google.com/admanager/answer/6123557).\nThe following sample stream is available for viewability testing:\n\n\u003cbr /\u003e\n\nCMS ID: \"2556080\", video ID: \"tears-of-steel-omid\"\n\nTo test using this stream, first check the network logs for\n`ima-test-verification.js` to be downloaded and then a ping fired to\n`https://pagead2.googlesyndication.com/pagead/gen_204` at the start of ad\nplayback.\n\n| **Note:** If you use your own video display and maintain full control over playback, you might need to modify your layout to ensure that the necessary metrics are being correctly returned.
