Google Analytics统计信息未更新

Question

我在项目中添加了最新的Google Play服务库，并希望使用Google Analytics进行屏幕跟踪。我已经为我的应用在GA中创建了一个新的属性和视图，但它没有显示我的任何应用活动。

我已经在下面的应用中添加了相关的代码段和XML。谁能告诉我我做错了什么？

global_tracker.xml：

    <?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <integer name="ga_sessionTimeout">300</integer>
    <bool name="ga_autoActivityTracking">true</bool>
    <screenName name="com.mypackage.MyApp.MainActivity">Main Activity</screenName>
    <string name="ga_trackingId">UA-nnnnnnn-10</string>

</resources>

的AndroidManifest.xml：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mypackage.MyApp"
    android:versionCode="2" >

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <application
        android:name=".MyApp"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <meta-data android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

申请类：

public class MyApp extends Application {
    private static final String PROPERTY_ID = "UA-nnnnnnn-10";
    public static int GENERAL_TRACKER = 0;

    public enum TrackerName {
        APP_TRACKER, GLOBAL_TRACKER, ECOMMERCE_TRACKER,
    }

    public HashMap mTrackers = new HashMap();

    public MyApp() {
        super();
    }

    public synchronized Tracker getTracker(TrackerName appTracker) {
        if (!mTrackers.containsKey(appTracker)) {
            GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
            Tracker t = (appTracker == TrackerName.APP_TRACKER) ? analytics.newTracker(PROPERTY_ID) : (appTracker == TrackerName.GLOBAL_TRACKER) ? analytics.newTracker(R.xml.global_tracker) : analytics.newTracker(R.xml.ecommerce_tracker);
            mTrackers.put(appTracker, t);
        }
        return (Tracker) mTrackers.get(appTracker);
    }

    }

MainActivity：

public class MainActivity extends ActionBarActivity {
Boolean debugging_on;
final static Logger logger = LoggerFactory.getLogger(UploadService.class);

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    try {
        Tracker t = ((MyApp) getApplication()).getTracker(TrackerName.APP_TRACKER);
        t.setScreenName("Home");
        t.send(new HitBuilders.AppViewBuilder().build());
    } catch (Exception e) {
        e.printStackTrace();
    }
