IMA SDK html5 "Failed to initialize ad playback element before starting ad playback."

[Ariel Kriss]

Hi there, I've just moved from the old Flash version of IMA SDK to the new V3 IMA SDK.

it is working well enough on desktop but on android mobile I am getting this error every time: "Failed to initialize ad playback element before starting ad playback."

this is not an autoplay video, and I couldn't find any solution for this.

Hi Ariel,

Thank you for reaching out to support. Because the HTML5 IMA SDK does not allow for autoplay on Android or iOS, ad playback must be initialized via user action on these platforms.

This is further outlined in our FAQ :

On mobile devices, you must call adDisplayContainer.initialize() as the result of a user action (e.g. tap). If you're seeing this error, you're most likely calling it on a non-user-initiated context. Note that it must be the direct result of a user action. For example, if you respond to a 'tap' event by playing a video, and then use the video player's 'play' event to call initialize(), you will see this error - you must call initialize() as the result of the tap event itself.

Hi Ariel,

I understand that you are not using an autoplay video. Regardless, the adDisplayContainer initialization must be the direct result of a user action.

From the page you linked, I can see that you don't use the adDisplayContainer.initialize() method at all. Take a look at our advanced HTML5 sample. You'll see that playAds(), which invokes adDisplayContainer.initialize(), is called directly after the user presses the play button. This step must not be omitted if the SDK is to behave predictably. Correctly initializing the adDisplayContainer will fix your issues on mobile.
