Google Analytics API v4 для Android: сбой приложения при запуске

я сделал все шаги.

Я запускаю свое приложение, но происходит сбой

Вот мой global_tracker.xml

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

    <!-- The apps Analytics Tracking Id -->
    <string name="ga_trackingId">UA-XXXXXX-15</string>

    <!-- Percentage of events to include in reports -->
    <string name="ga_sampleFrequency">100.0</string>

    <!-- Enable automatic Activity measurement -->
    <bool name="ga_autoActivityTracking">true</bool>

    <!-- catch and report uncaught exceptions from the app -->
    <bool name="ga_reportUncaughtExceptions">true</bool>

    <!-- How long a session exists before giving up -->
    <integer name="ga_sessionTimeout">-1</integer>

    <!-- If ga_autoActivityTracking is enabled, an alternate screen name can be specified to substitute for the full length canonical Activity name in screen view hit. In order to specify an alternate screen name use an <screenName> element, with the name attribute specifying the canonical name, and the value the alias to use instead. -->
    <screenName name="com.example.test.MainActivity">MainActivity</screenName>
</resources>

Вот мой AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.test">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:name=".Global"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/Theme.AppCompat">
        <activity

            </intent-filter>

        </activity>

        <activity
            android:name=".SelectedImageActivity"

        <!-- Google Analytics Version v4 needs this value for easy tracking -->
        <meta-data android:name="com.google.android.gms.analytics.globalConfigResource"
            android:resource="@xml/global_tracker" />

        <activity

            android:screenOrientation="portrait" />
    </application>

</manifest>

Вот мой AnalyticsApplication.java

 public enum TrackerName {
    APP_TRACKER,
    GLOBAL_TRACKER,
    E_COMMERCE_TRACKER,
}
HashMap<TrackerName, Tracker> mTrackers = new HashMap<TrackerName, Tracker>();
synchronized Tracker getTracker(TrackerName trackerId) {
    if (!mTrackers.containsKey(trackerId)) {
        GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
        analytics.getLogger().setLogLevel(Logger.LogLevel.VERBOSE);
        Tracker t = null;
        if(trackerId==TrackerName.GLOBAL_TRACKER){
            t= analytics.newTracker("UA-66XXXXX-1");
        }
        mTrackers.put(trackerId, t);
    }
    return mTrackers.get(trackerId);
}

}

Вот мой класс MainActivity:

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

        getWindow().setSoftInputMode(
                WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

        setContentView(R.layout.activity_main);
        getSupportActionBar().hide();

        //Get a Tracker (should auto-report) 2
        Tracker tracker = ((AnalyticsApplication) getApplication()).getTracker(AnalyticsApplication.TrackerName.GLOBAL_TRACKER);
        tracker.setScreenName("MainActivity");

///////////////////////////////////////////////////////////

@Override
    protected void onStart() {
        super.onStart();
        GoogleAnalytics.getInstance(this).reportActivityStart(this);
    }

    @Override
    protected void onStop() {
        super.onStop();
        GoogleAnalytics.getInstance(this).reportActivityStop(this);
    }

Моя Build Gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Сборка Gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.example.test"
        minSdkVersion 16
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"


    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile files('libs/main.jar')

     compile 'com.android.support:appcompat-v7:22.2.1'
