Are you interested in tracking your Android app activities? If yes, Google Analytics provides a service for which real time tracking of Activities, fragments, events, exceptions and crash reports can be done easily.

Steps to integrate Google Analytics:-

Step1:- Sign-in to Google Analytics Account
Select tracking to mobile app, add account name, App name, category of app, country wise time zone and select Get tracking id. You will get a tracking-id and save it as seperate.

Step2:- Apply plugin and under build.gradel add google analytics dependency and synchronize the app

dependencies {

  compile 'com.google.android.gms:play-services-analytics:8.4.0'
}

Step3:- Permissions needed:

 <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Step4:- Create folder xml inside res directory, now create a file analytics_tracker.xml and put below code inside it. The tracking id we get after sign-in to the google analytics account have to place inside the tag ga_trackingId.

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <!-- End current session if app sleeps for_image a period of time -->
  <integer name="ga_sessionTimeout">300</integer>

  <!-- Enable automatic Activity measurement -->
  <bool name="ga_autoActivityTracking">true</bool>

  <!-- The property id associated with this analytics tracker -->
  <string name="ga_trackingId">UA-XXXXXXXX-X</string>

  <string name="ga_sampleFrequency">100.0</string>

  <bool name="ga_reportUncaughtExceptions">true</bool>

</resources>

Step5:- Create AnalyticsTracker class in your utility package, initialize the tacker before getInstance().

public final class AnalyticsTracker {

  public enum Target {
    APP
  }

  private static AnalyticsTracker sInstance;

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

    sInstance = new AnalyticsTracker(context);
  }

  public static synchronized AnalyticsTracker 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;

  // creating the instance of class
  private AnalyticsTracker(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.analytics_tracker);
          break;
        default:
          throw new IllegalArgumentException("Unhandled analytics target " + target);
      }
      mTrackers.put(target, tracker);
    }

    return mTrackers.get(target);
  }
}

Step6:- Call below methods to initialize the tracker in your application class.

AnalyticsTrackers.initialize(this);
AnalyticsTrackers.getInstance().get(AnalyticsTrackers.Target.APP);
