开始时适用于Android应用的Google Analytics API v4崩溃

Question

我已经为Google Analytics（分析）API v4设置了所有功能，如此处所述： https : //developers.google.com/analytics/devguides/collection/android/v4/以及此处： http : //www.javacodegeeks.com/2014 /04/working-with-google-analytics-api-v4-for-android.html

我完成了所有步骤。

我运行我的应用程序但崩溃了

这是我的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>

这是我的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
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait">
            <intent-filter>

            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

        </activity>

        <activity
            android:name=".SelectedImageActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait">

        </activity>

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

        <!-- 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:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
            android:screenOrientation="portrait" />
    </application>

</manifest>

这是我的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);
}

}

这是我的MainActivity类：

 @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);
    }

我的构建摇篮 ：

// 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()
    }
}

构建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'
        }
    }
}

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

     compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.commit451:NativeStackBlur:1.0.1'
    compile 'com.google.android.gms:play-services-ads:7.3.0'
    compile 'com.squareup.picasso:picasso:2.5.0'
    compile 'com.github.bumptech.glide:glide:3.6.1'
    compile 'com.android.support:support-v4:21.0.0'
  }

Answer 1

在清单中，您已报告：

<application 
    android:name=".Global"

根据您的堆栈跟踪， AnalyticsApplication是Application类，因此应为：

<application 
    android:name=".AnalyticsApplication"
