android - How to manually end a session in Google analytics v4 for Android?

Question

I've been searching online for a few days but I couldn't find it. It was available in v3 but the only code available for managing the session manually in v4 is for starting a new one only and rely on the session timeout for the ending.

公共 Android v4 api 不支持结束会话，但您可以使用Measurement Protocol中的会话控制结束参数来完成相同的操作。您可以通过将 sc=end 添加到您的跟踪器来做到这一点：

analytics = GoogleAnalytics.getInstance(getApplicationContext());

// TODO: Remove this line before shipping
analytics.getLogger().setLogLevel(Logger.LogLevel.VERBOSE);

tracker = analytics.newTracker(TRACKER_ID);
Map<String, String> hit = new HitBuilders.ScreenViewBuilder().build();
hit.put("&sc", "end");
tracker.send(hit);

通过查看 logcat 的“Sending hit”行来验证 sc 参数是否已发送，并确保它具有 sc=end 参数。它应该看起来像这样：
