[Unity] [iOS] Getting exception related to orientation when trying to play Interstitial Ad

[Leonardo Bilck]

Hello,

We are trying to update our app with the latest AdMob for Unity SDK, but we are getting the following error on iOS:

• 2019-05-06 16:50:57.824261-0300 monicatv[262:5076] <Google> Presenting the interstitial threw exception: Supported orientations has no common orientation with the application, and [GADFullScreenAdViewController shouldAutorotate] is returning YES with trace: ...

Everything works fine on Android but not on iOS.

Here are some code snippets that lead to the bug:

private IEnumerator PlayNextVideoCoRoutine()

        {

            MediaPlayerCtrl.Stop();

            MarkCurrentVideoAsWatched();

            var backupOrientation = Screen.orientation;
            // Reverts to AutoRotation (workaround for AdMob)
            // Please note that at this moment the app has probably locked the orientation to Landscape for gameplay purposes

            Screen.orientation = ScreenOrientation.AutoRotation;

            while(Screen.orientation != ScreenOrientation.AutoRotation) yield return null;

            yield return null;

            yield return AdsController.Instance.TryPlayVideoAdCoRoutine();

            yield return null;

            yield return null;

            Screen.orientation = backupOrientation;

            while(Screen.orientation != backupOrientation) yield return null;

            yield return null;

            

            StartPlayRandomVideoCoroutine(_playingMultipleVideos);

            _controlsPlaybackGroup.PerformTransitionControlsGroup(VideoPlayerControlState.Inactive);

        }

public IEnumerator TryPlayVideoAdCoRoutine()

        {

            if (!CanShowAds) yield break;

            Debug.LogFormat("TRYING TO PLAY VIDEO AD - {0}", GameController.Instance.UserData.MustShowVideoAdToUserAsap);

            if (!GameController.Instance.UserData.MustShowVideoAdToUserAsap) yield break;

            Debug.Log("PLAYING VIDEO AD");

            Future<bool> adResultFuture = new Future<bool>();

            PlayVideoAd(adResultFuture);

            while (!adResultFuture.IsFinished) yield return null;

            if (adResultFuture.Value) SaveVideosWatchedUserData();

            Debug.Log("FINISHED PLAYING VIDEO AD");

            yield return null;

        }

private void PlayVideoAd(Future<bool> adResultFuture)

        {

            if (Application.isEditor)

            {

                Debug.LogWarning("PLAYING MOCK VIDEO AD!!!");

                EvtVideoAdPlayed?.Invoke();

                adResultFuture.Value = true;

                return;

            }

            TryInit();

            if (_adResultFuture != null) Debug.LogWarning("[AdController] Trying to play video ad but there is already an Ad Result Future defined!");

            _adResultFuture = adResultFuture;

            if (!_interstitialAd.IsLoaded())

            {

                Debug.Log("[AdController] Video Not Available");

                

                adResultFuture.Value = false;

                return;

            }

            Debug.LogFormat("[AdController] Playing Video Ad");

            _interstitialAd.OnAdClosed += (sender, args) =>

            {

                Debug.LogFormat("[AdController] Ad Finished Playing");

                adResultFuture.Value = true;

            };

            _interstitialAd.Show();

        }

Hi,

Thank you for reporting this.

I already checked this with the team and this crash can also be triggered by publishers attempting to present SDK VCs on their own. Any publishers doing this need to update their own apps, as there's not much we can do to guard against publishers using our internals.

That said, I suggest to check our sample app implementation in reference, to avoid this crash.

I have managed to fix/workaround this issue.

How? 

1. Just before displaying an Interstitial Ad I force Unity's orientation to AutoRotation;
2. Since Unity doesn't have a callback for orientation change AND doesn't set the current orientation to "AutoRotation" I wait an arbitrary time (1 sec) to make sure that the rotation properties are properly set;
3. Show Ad (that is already loaded)

The main issue in this solution is that the orientation could be set/enforced by the Google Mobile Ads plugin, which in turn could properly handle the orientation changes.

This is the workaround code that I modified:

public IEnumerator TryPlayVideoAdCoRoutine()

        {

            if (!CanShowAds) yield break;

#if UNITY_EDITOR || DEVELOPMENT_BUILD

            Debug.LogFormat("[AdsController] TRYING TO PLAY VIDEO AD - {0}", GameController.Instance.UserData.MustShowVideoAdToUserAsap);

#endif

            if (!GameController.Instance.UserData.MustShowVideoAdToUserAsap) yield break;

            

#if UNITY_EDITOR || DEVELOPMENT_BUILD

            Debug.LogFormat("[AdsController] Changing Screen Orientation to {0}", ScreenOrientation.AutoRotation);

#endif

            var backupOrientation = Screen.orientation;

            Screen.orientation = ScreenOrientation.AutoRotation;

            

            yield return null;

            const float orientationChangeTimeout = 1f;

            float nextTimeout = Time.unscaledTime + orientationChangeTimeout;

            while(Screen.orientation != ScreenOrientation.AutoRotation && Time.unscaledTime < nextTimeout)

                yield return null;

            

#if UNITY_EDITOR || DEVELOPMENT_BUILD

            Debug.LogFormat("[AdsController] Screen Orientation Changed to {0}", Screen.orientation);

#endif

            

            Debug.Log("[AdsController] PLAYING VIDEO AD");

            Future<bool> adResultFuture = new Future<bool>();

            PlayVideoAd(adResultFuture);

            while (!adResultFuture.IsFinished) yield return null;

            

            Screen.orientation = backupOrientation;

            yield return null;

            nextTimeout = Time.unscaledTime + orientationChangeTimeout;

            while(Screen.orientation != backupOrientation && Time.unscaledTime < nextTimeout)

                yield return null;

            

#if UNITY_EDITOR || DEVELOPMENT_BUILD

            Debug.LogFormat("[AdsController] Screen Orientation Changed BACK to {0}", Screen.orientation);

#endif

            

            if (adResultFuture.Value) SaveVideosWatchedUserData();

            Debug.Log("[AdsController] FINISHED PLAYING VIDEO AD");

            yield return null;

        }

If anyone is interested I have attached my AdsController class in this post. Obviously it won't work out of the box since it contains some references to other classes in the project.
