如何在从旧版Eclipse ADT导入的Android Studion中的项目上实施Google Analytics v4

Question

我的遗留应用程序项目没有Application类。 因此，official document无济于事 我不知道下面的代码应该去哪里：

/**
 * Enum used to identify the tracker that needs to be used for tracking.
 *
 * A single tracker is usually enough for most purposes. In case you do need multiple trackers,
 * storing them all in Application object helps ensure that they are created only once per
 * application instance.
 */
public enum TrackerName {
  APP_TRACKER, // Tracker used only in this app.
  GLOBAL_TRACKER, // Tracker used by all the apps from a company. eg: roll-up tracking.
  ECOMMERCE_TRACKER, // Tracker used by all ecommerce transactions from a company.
}

HashMap<TrackerName, Tracker> mTrackers = new HashMap<TrackerName, Tracker>();

这些代码：

synchronized Tracker getTracker(TrackerName trackerId) {
  if (!mTrackers.containsKey(trackerId)) {

    GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
    Tracker t = (trackerId == TrackerName.APP_TRACKER) ? analytics.newTracker(PROPERTY_ID)
        : (trackerId == TrackerName.GLOBAL_TRACKER) ? analytics.newTracker(R.xml.global_tracker)
            : analytics.newTracker(R.xml.ecommerce_tracker);
    mTrackers.put(trackerId, t);

  }
  return mTrackers.get(trackerId);
}

我已经导入了googleAnalytics的这些库。

但我仍然无法导入像this way这样的库：

import com.google.android.apps.analytics.GoogleAnalyticsTracker;

而且，因为我使用的是Android Studio 1.2 Beta3，the tutorial based on Eclipse也不适合我的情况。

有没有简单的方法在Android应用上实施Google Analytics？就像在iOS中初始化一样？

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [GAI sharedInstance].trackUncaughtExceptions = YES;
  [GAI sharedInstance].dispatchInterval = 20;
  [[[GAI sharedInstance] logger] setLogLevel:kGAILogLevelVerbose];
  [[GAI sharedInstance] trackerWithTrackingId:@"UA-XXXX-Y"];
}

在Android上简单完整地实施Google Analytics需要：

1. 链接到Google Play服务（看起来您已经完成了这项工作）
2. 在您的应用清单中添加required network permissions。
3. Extend Android Application class，override onCreate并设置您的app class implementation in the <android name='you_app_class'> name属性。
4. 在onCreate create new tracker中并将其保存在静态var tracker = GoogleAnalytics.getInstance（context）.newTracker（）;启用screens, exceptions等的自动报告
5. 在您的Application Manifest中注册AnalyticsReceiver & AnalyticsService。
