谷歌分析-在AsyncTask中发送的NetworkOnMainThreadException

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中实现发送跟踪器,或者如果一次进行Application class就足够了,但这是另一个故事.目前Google Analytics正在实施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.然后我NetworkOnMainThreadException在尝试调度事件时遇到错误.

它是在哪里试图调度事件,而上dryRun,造成NetworkOnMainThreadException没有少？它不应该在开启时将所有内容发送到Logcat dryRun吗？那我该如何应对dryRun呢？

起初我试图像这样实现它,没有额外的AsyncTask类,假设我将所有内容转储到Logcat,但是当我NetworkOnMainThreadException第一次得到错误时,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)

                                            .build());

            dataTracker.setScreenName(screenName);
            dataTracker.send(new HitBuilders.SocialBuilder()                 
                                            .setNetwork(SocialNetworkName)  // Set the Social Network Name [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.
