分析跟踪器:-

public final class AnalyticsTrackers {

    public enum Target {
        APP,
        // Add more trackers here if you need, and update the code in #get(Target) below
    }

    private static AnalyticsTrackers sInstance;

    public static synchronized void initialize(Context context) {
        if (sInstance != null) {
            throw new IllegalStateException("Extra call to initialize analytics trackers");
        }

        sInstance = new AnalyticsTrackers(context);
    }

    public static synchronized AnalyticsTrackers getInstance() {
        if (sInstance == null) {
            throw new IllegalStateException("Call initialize() before getInstance()");
        }

        return sInstance;
    }

    private final Map<Target, Tracker> mTrackers = new HashMap<Target, Tracker>();
    private final Context mContext;

    /**
     * Don't instantiate directly - use {@link #getInstance()} instead.
     */
    private AnalyticsTrackers(Context context) {
        mContext = context.getApplicationContext();
    }

    public synchronized Tracker get(Target target) {
        if (!mTrackers.containsKey(target)) {
            Tracker tracker;
            switch (target) {
                case APP:
                    tracker = GoogleAnalytics.getInstance(mContext).newTracker(R.xml.app_tracker);
                    break;
                default:
                    throw new IllegalArgumentException("Unhandled analytics target " + target);
            }
            mTrackers.put(target, tracker);

Answer 1

只要“ga_autoActivityTracking”设置为 true，就会使用上面描述的 XML 配置 (app_tracker.xml)。这意味着只要 Activity 启动，跟踪就会自动报告新的屏幕 View 。这意味着如果您手动配置/发送屏幕名称不会出现在报告中。因此您必须将 ga_autoActivityTracking 设置为 false。

<!-- off automatic Activity measurement -->
<bool name="ga_autoActivityTracking">false</bool>
