Google Analytics（分析） - 在AsyncTask中发送的NetworkOnMainThreadException

Question

我必须在我正在处理的应用中实施Google Analytics。 我正在使用Android Studio。

我不太确定我是否应该从每个Activity实现发送跟踪器，或者如果在Application class执行一次就足够了，但这是另一个故事。 目前，Google Analytics在Application class 。 它尝试连接到某些东西（虽然我已设置dryRun ），失败，然后什么也没说，除非我导致我的应用程序崩溃。 然后，当我尝试分派事件时，我收到NetworkOnMainThreadException错误。

在dryRun上尝试调度事件的位置在dryRun ，导致NetworkOnMainThreadException不会减少？ 在dryRun上它不应该把所有东西都发送到dryRun吗？ 我应该如何在dryRun上处理它而不是？

起初我尝试实现它，没有额外的AsyncTask类，假设我将所有内容转储到Logcat，但是当我第一次得到NetworkOnMainThreadException错误时，我实现了AsyncTask类。

logcat的：

UPD：感谢@Bart Hofma，我意识到我可能会因为我的应用崩溃而感到困惑。 当GA尝试调度事件时，我的应用程序不会崩溃。 相反，GA只在我的应用程序崩溃时尝试调度事件，否则它会保持沉默。 我故意崩溃我的应用程序，看看GA可能会说些什么。 我有一个自定义视频播放器，可以在真实设备上正常工作，但在虚拟机上崩溃，所以当我希望我的应用程序崩溃时，我只是转到VM上的播放器Activity。

您必须从线程中调用Google Analytics。 在这里，我正在分享我正在使用的代码。

将此代码放在一个类中（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.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());
        }
} 

现在你必须调用这个类实例，方法并提供调用类所需的数据，如下所示：

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

并调用此方法：

sendScreenView（“Home Activity”）;

希望你会发现它很有帮助。

Answer 2

我浪费了一天时间来搜索解决方案（我有相同的线程转储行），并发布它与Google Analytics没有直接关系。 根本原因是下一行：adView.destroy（）; 其中adView == null。 似乎Google Analytics尝试发送此异常并自行崩溃。 我发现它完全取消了Google Analytics。
