Exoplayer analytics total join time - app crashing

Question

I'm trying to get the total join time in before a video starts using the Exoplayer Demo App , but the app just crashes when I launch the app with the code for this.

I've initiated the playback stats listener as follows in PlayerActivity.js

protected PlaybackStatsListener playerStatsListener = new PlaybackStatsListener(true, null);

Following that, I add that to my player using addAnalyticsListener

player.addAnalyticsListener(playerStatsListener)

Within the onCreate method , I try to retrieve the totalJoinTimeMs using this code:

long totalValidJoinTimeMs = playerStatsListener.getPlaybackStats().getTotalJoinTimeMs();

However, the app just crashes when I have included the above line of code.

Are there code examples of how this should be done?

You can pass a callback to PlaybackStatsListener to be called when the PlaybackStats is ready. You can use the following snippet to read analytics stats from exoplayer:

       player.addAnalyticsListener(new PlaybackStatsListener(true, new PlaybackStatsListener.Callback() {
            @Override
            public void onPlaybackStatsReady(AnalyticsListener.EventTime eventTime, PlaybackStats playbackStats) {
                // read PlaybackStats fields or call methods here
                playbackStats.getTotalJoinTimeMs();
                ...
            }
        }));
