我怎么能解决这个崩溃？ 我知道这是由谷歌分析引起的，但我不明白为什么我遵循谷歌的正确指南如何实现它！

分析类

   public void onCreate() {

    super.onCreate();
    context = getApplicationContext();
    mNotificationManager = (NotificationManager) getSystemService("notification");
    mInstance = this;
    AnalyticsTrackers.getInstance().get(AnalyticsTrackers.Target.APP);
    AnalyticsTrackers.initialize(this);


}

public static synchronized NotificationService getInstance() {
    return mInstance;
}

public synchronized Tracker getGoogleAnalyticsTracker() {
    AnalyticsTrackers analyticsTrackers = AnalyticsTrackers.getInstance();
    return analyticsTrackers.get(AnalyticsTrackers.Target.APP);
}

/***
 * Tracking screen view
 *
 * @param screenName screen name to be displayed on GA dashboard
 */
public void trackScreenView(String screenName) {
    Tracker t = getGoogleAnalyticsTracker();

    // Set screen name.
    t.setScreenName(screenName);

    // Send a screen view.
    t.send(new HitBuilders.ScreenViewBuilder().build());

    GoogleAnalytics.getInstance(this).dispatchLocalHits();
}

/***
 * Tracking exception
 *
 * @param e exception to be tracked
 */
public void trackException(Exception e) {
    if (e != null) {
        Tracker t = getGoogleAnalyticsTracker();

        t.send(new HitBuilders.ExceptionBuilder()
                        .setDescription(
                                new StandardExceptionParser(this, null)
                                        .getDescription(Thread.currentThread().getName(), e))
                        .setFatal(false)
                        .build()
        );
    }
}

/***
 * Tracking event
 *
 * @param category event category
 * @param action   action of the event
 * @param label    label
 */
public void trackEvent(String category, String action, String label) {
    Tracker t = getGoogleAnalyticsTracker();

    // Build and send an Event.
    t.send(new HitBuilders.EventBuilder().setCategory(category).setAction(action).setLabel(label).build());
}

所以我初始化跟踪器和跟踪器属性是在一个单独的XML文件中，但它的行为就像我正在尝试初始化它两次或者其他东西而且我不太确定它为什么会发生！ 谢谢你的帮助！

Answer 1

尝试将initialize移动到app类，因此它将在应用程序生命周期中调用一次。

public class MyApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        AnalyticsTrackers.initialize(this);
    }
}

Answer 2

您需要将跟踪器实例初始化为onCreate方法。

AnalyticsApplication application = (AnalyticsApplication) getApplication();
myTracker = application.getDefaultTracker();

然后重写onResume方法以设置跟踪器。

myTracker.setScreenName("ScreenName" + name);
myTracker.send(new HitBuilders.ScreenViewBuilder().build());

Answer 3

initialize方法检查变量mInstance是否为null，如果不是，则抛出异常。 好吧，你打破你的程序，因为你在初始化之前给mInstance一个非null值。 不要那样做。

看看你自己的代码：

mInstance = this; //Don't do that
AnalyticsTrackers.getInstance().get(AnalyticsTrackers.Target.APP);
AnalyticsTrackers.initialize(this); //☠
