谷歌分析v4在Android崩溃

Question

我想跟踪我的应用程序统计使用谷歌分析。我试图按照几个人发布的http://java.dzone.com/articles/working-google-analytics-api教程进行操作，并表示它适用于他们。这里是我的代码：

我app_tracker.xml文件低于

<?xml version="1.0" encoding="utf-8"?> 
<resources 
xmlns:tools="http://schemas.android.com/tools" 
tools:ignore="TypographyDashes"> 
<span style="line-height: 1.5; font-style: inherit; font-weight: inherit;"> 
</span> 

<string name="ga_trackingId">UA-XXXXXXX-1</string> 

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

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

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

<integer name="ga_sessionTimeout">-1</integer> 


<screenName name="game">game</screenName> 
<screenName name="settings">settings</screenName> 
</resources> 

我global_tracker XML文件如下：

<?xml version="1.0" encoding="utf-8"?> 
<resources 
xmlns:tools="http://schemas.android.com/tools" 
tools:ignore="TypographyDashes"> 

<span style="line-height: 1.5; font-style: inherit; font-weight: inherit;"> 

</span> 

<string name="ga_logLevel">verbose</string> 

<integer name="ga_dispatchPeriod">30</integer> 

<bool name="ga_dryRun">false</bool> 

<string name="games">games</string> 
<string name="settings">settings</string> 
</resources> 

在我的清单文件

我已经进入下面的代码块：

<meta-data android:name="com.google.android.gms.version" 
android:value="@integer/google_play_services_version" /> 

我的主要活动是这样的：

import com.google.android.gms.analytics.GoogleAnalytics; 
import com.google.android.gms.analytics.Tracker; 

public class MainActivity extends Activity implements View.OnClickListener { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 

((MyApplication)getApplication()).getTracker(MyApplication.TrackerName.APP_TRACKER); 

} 

其中该应用应当具有的所有MyApplication类是当程序运行如下

public class MyApplication extends Application { 


private static final String PROPERTY_ID = "UA-XXXXXXXX-1"; 

private static final String TAG = "MyApp"; 

public static int GENERAL_TRACKER = 0; 

public enum TrackerName { 
APP_TRACKER, // Tracker used only in this app. 
GLOBAL_TRACKER, // Tracker used by all the apps from a company. eg: roll-up tracking. 
ECOMMERCE_TRACKER, // Tracker used by all ecommerce transactions from a company. 
} 

HashMap<TrackerName, Tracker> mTrackers = new HashMap<TrackerName, Tracker>(); 

public MyApplication() { 
super(); 
} 

synchronized Tracker getTracker(TrackerName trackerId) { 
if (!mTrackers.containsKey(trackerId)) { 

GoogleAnalytics analytics = GoogleAnalytics.getInstance(this); 
Tracker t = (trackerId == TrackerName.APP_TRACKER) ? analytics.newTracker(PROPERTY_ID) 
: (trackerId == TrackerName.GLOBAL_TRACKER) ? analytics.newTracker(PROPERTY_ID) 
: analytics.newTracker(R.xml.ecommerce_tracker); 
mTrackers.put(trackerId, t); 

} 
return mTrackers.get(trackerId); 
} 
} 

，当它到达在主活性的线

((MyApplication)getApplication()).getTracker(MyApplication.TrackerName.APP_TRACKER); 

它崩溃。我花了数周的时间试图找到解决办法，但没有成功。有人可以帮我在我的android项目中配置谷歌分析v4吗？

我编辑这个（因为我得到同样的问题）&这里去了logcat的

线73为运算提到它崩溃的应用程序相同的线。

注：我在仿真器上测试它。此功能是否需要在真实设备上进行测试（安装了Play商店）？

您需要在清单文件中添加应用程序名称。

<application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:name=".MainApplication" > 
</application>
