Question

我已将IMA SDK添加到我的项目中以播放VAST广告。我发现了一个奇怪的问题-在会话onAdError(AdErrorEvent adErrorEvent)和onAdEvent(AdEvent adEvent)的10-15分钟后没有被调用。因此，如果我运行我的应用程序并从列表中选择一个视频文件，那么我会看到广告，并且在广告制作完成后开始播放视频。在这种情况下，onAdEvent(AdEvent adEvent)被称为（ALL_ADS_COMPLETED）。如果我选择下一个视频，服务器将返回空的VAST XML，因此将调用onAdError(AdErrorEvent adErrorEvent)，并启动另一个视频。 10-15分钟后，如果我从列表中选择一个视频，则两个事件均未调用，并且没有任何反应，因为我的播放器正在从这些事件的列表中开始播放视频。

BasicExample 项目中的所有代码。

源代码：

        OnCreate() {
             mSdkFactory = ImaSdkFactory.getInstance();
             mAdsLoader = mSdkFactory.createAdsLoader(this);
             mAdUiContainer = (ViewGroup) findViewById(R.id.videoPlayerWithAdPlayback);

             mAdsLoader.addAdErrorListener(this);
             mAdsLoader.addAdsLoadedListener(new AdsLoadedListener() {
             @Override
             public void onAdsManagerLoaded(AdsManagerLoadedEvent adsManagerLoadedEvent) {
             // Ads were successfully loaded, so get the AdsManager instance. AdsManager has
             // events for ad playback and errors.
                mAdsManager = adsManagerLoadedEvent.getAdsManager();

             // Attach event and error event listeners.
                mAdsManager.addAdErrorListener(MainActivity.this);
                mAdsManager.addAdEventListener(MainActivity.this);
                mAdsManager.init();
              }
             });
            }

            @Override
            public void onAdEvent(AdEvent adEvent) {
            Log.i(LOGTAG, "Event: " + adEvent.getType());

            // These are the suggested event types to handle. For full list of all ad event
           // types, see the documentation for AdEvent.AdEventType.
           switch (adEvent.getType()) {
                case LOADED:
                                    // AdEventType.LOADED will be fired when ads are ready to be played.
                                    // AdsManager.start() begins ad playback. This method is ignored for VMAP or
                                    // ad rules playlists, as the SDK will automatically start executing the
                                    // playlist.
                   mAdsManager.start();
                   break;
                case CONTENT_PAUSE_REQUESTED:
                                    // AdEventType.CONTENT_PAUSE_REQUESTED is fired immediately before a video
                                    // ad is played.
                   mIsAdDisplayed = true;
                   mVideoPlayer.pause();
                   break;
                case CONTENT_RESUME_REQUESTED:
                                    // AdEventType.CONTENT_RESUME_REQUESTED is fired when the ad is completed
                                    // and you should start playing your content.
                   mIsAdDisplayed = false;
                   mVideoPlayer.play();
                   break;
                case ALL_ADS_COMPLETED:
                   mIsAdDisplayed = true;
                   if (mAdsManager != null) {
                         mAdsManager.destroy();

                       }
                   }

        @Override

        private void requestAds(String adTagUrl) {

             AdDisplayContainer adDisplayContainer = mSdkFactory.createAdDisplayContainer();
             adDisplayContainer.setAdContainer(mAdUiContainer);

             // Create the ads request.
             AdsRequest request = mSdkFactory.createAdsRequest();
             request.setAdTagUrl(adTagUrl);
             appendLog("VAST Tag: " + adTagUrl);
             request.setAdDisplayContainer(adDisplayContainer);
             request.setContentProgressProvider(new ContentProgressProvider() {
             @Override
             public VideoProgressUpdate getContentProgress() {
                  if (mIsVastAdDisplayed || exoPlayer == null || exoPlayer.getDuration() <= 0) {
                  return VideoProgressUpdate.VIDEO_TIME_NOT_READY;
                                }
                  return new VideoProgressUpdate(exoPlayer.getCurrentPosition(),
                                        exoPlayer.getDuration());

                        // Request the ad. After the ad is loaded, onAdsManagerLoaded() will be called.
                  mAdsLoader.requestAds(request);
