I\'m not quite sure yet if I should implement sending tracker from every

You must call the google analytics from thread. Here i'm sharing the code what i'm working with.

Put this code inside a class(MBGoogleAnalyticsManager.java)

 import android.content.Context;
 import com.google.android.gms.analytics.GoogleAnalytics;
 import com.google.android.gms.analytics.HitBuilders;
 import com.google.android.gms.analytics.Tracker;


public class MBGoogleAnalyticsManager  
{
    private static final String TAG = "MBGoogleAnalyticsManager";
    private static MBGoogleAnalyticsManager instance = null;
    public String PROPERTY_ID = "UA-28454545-2";

    private Context context;
    private Tracker dataTracker;

    public static MBGoogleAnalyticsManager getInstance(Context c) 
        {
            if(instance == null) 
                {
                    System.out.println("MBGoogleAnalyticsManager new instance is created");
                    instance = new MBGoogleAnalyticsManager(c);
                }
            else
                {
                    System.out.println("MBGoogleAnalyticsManager instance is already avaiable");
                }
            return instance;
        }

    private MBGoogleAnalyticsManager(Context c)     
        {
            //super(c);
            context = c;
            GoogleAnalytics analytics = GoogleAnalytics.getInstance(context);   
            dataTracker = analytics.newTracker(PROPERTY_ID);
        }




      //==============================================================================
     //========================== Send a screen view =================================
    //================================================================================
    public synchronized void sendGoogleAnalyticsSreenView(String screenName)
        {               
            dataTracker.setScreenName(screenName);    // Set screen name.
            //dataTracker.setAppName("MovieBuddy");  // We can send the application name [String](Optional)
            //dataTracker.setAppVersion("2.2");     // We can send the application version [String](Optional)
            //dataTracker.setLanguage("Eng");      // We can send the language [String](Optional)
            //dataTracker.setSessionTimeout(300); // We can set the time for the session time out [Long](Optional)

            dataTracker.send(new HitBuilders.AppViewBuilder()    
                                            //.setNewSession()   // If want to start a new session (Optional)
                                            .build());
            System.out.println("Screen: "+screenName);
        }



      //==============================================================================
     //========================== Send A Click Event Hit =============================
    //================================================================================
    public synchronized void sendGoogleAnalyticsHitEvents(String screenName,String category,String action,String label)
        {       
            dataTracker.setScreenName(screenName);
            dataTracker.send(new HitBuilders.EventBuilder()         
                                            .setCategory(category) // Set the category of the event [String]
                                            .setAction(action)    // Set the action has taken for the event [String]
                                            .setLabel(label)     // Set the label of for the event [String]
                                            .build());
            System.out.println("Hit Label: "+label);
        }



      //==============================================================================
     //========================== Send A Exception Event =============================
    //================================================================================

    public synchronized void sendGoogleAnalyticsException(String screenName,String ExceptionMethodName,String ExceptionLocation,boolean ExceptionFatal)
        {   
            dataTracker.setScreenName(screenName);
            dataTracker.send(new HitBuilders.ExceptionBuilder()                                         
                                            .setDescription(ExceptionMethodName + ":" + ExceptionLocation) // Send the exception details [String]
                                                                                                          //(Never send the e.message, as it contains personal info)
                                            .setFatal(ExceptionFatal)                                    // Send true or false if fatal exception error [boolean]
                                            .build());
        }



      //==============================================================================
     //================ Send A Social Event Interaction With target ==================
    //================================================================================
    public synchronized void sendGoogleAnalyticsSocialInteractionWithTarget(String screenName,String SocialNetworkName,String SocialAction,String SocialTarget)
        {       
            dataTracker.setScreenName(screenName);
            dataTracker.send(new HitBuilders.SocialBuilder()                 
                                            .setNetwork(SocialNetworkName)  // Set the Social Network Name [String]
                                            .setAction(SocialAction)       // Set the action [String]
                                            .setTarget(SocialTarget)      // Set the target [String](Not a mandatory field)
                                            .build());
            System.out.println("Target: "+SocialTarget);
        }




      //==============================================================================
     //============== Send A Social Event Interaction Without target =================
    //================================================================================

    public synchronized void sendGoogleAnalyticsSocialInteraction(String SocialNetworkName,String SocialAction)
        {       
            dataTracker.send(new HitBuilders.SocialBuilder()
                                            .setNetwork(SocialNetworkName)// Set the Social Network Name [String]
                                            .setAction(SocialAction)     // Set the action [String]
                                            .build());
        }
} 

Now you have to call this class instance,method and provide the required data from you calling class like this:

private void sendScreenView(final String screenName)
    {   
        new Thread(new Runnable() 
            {
                @Override
                public void run() 
                    {                           
                        analyticsManager = MBGoogleAnalyticsManager.getInstance(getApplicationContext());
                        analyticsManager.sendGoogleAnalyticsSreenView(screenName);
                    }
            }).start();
    }

And Call this method:

sendScreenView("Home Activity");

Hope you will find it helpful.

I wasted a day on searching the solution (I have the same lines of the thread dump) and released that it's not directly related to Google Analytics. The root cause was the next line: adView.destroy(); where adView == null. Seems Google Analytics tried to send this exception and crashed itself. I found it by disabling Google Analytics at all.
