Google Analytics（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，当它尝试调度事件时，我收到NetworkOnMainThreadException错误。
尝试在dryRun上调度事件的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：

申请类（相关部分）：
public class App extends Application { private static App context = null; private static final String PROPERTY_ID = "UA-xxxxxxxx-1"; private GoogleAnalytics analytics; private Tracker t; public void onCreate() { super.onCreate(); if (context == null) context = (App) getApplicationContext(); try { analytics = GoogleAnalytics.getInstance(context); t = analytics.newTracker(R.xml.app_tracker); new SendTrackerInBg(t); } catch (Exception e) {e.printStackTrace();} }
SendTrackerInBg：
public class SendTrackerInBg extends AsyncTask { SendTrackerInBg(Tracker t) { this.execute(t); } @Override protected Integer doInBackground(Tracker... trackers) { try { trackers[0].send(new HitBuilders.AppViewBuilder().build()); return 0; } catch (Exception e) { e.printStackTrace(); return -1; } } }

清单（相关部分）：
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。 我故意让我的应用程序崩溃，看看GA可能会说些什么。 我有一个自定义video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.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()); } }
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。
我浪费了一天的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exception并自行崩溃。 我发现它完全取消了Google Analytics。
