安卓崩溃上的java google analytics v4
我正在尝试使用谷歌分析追踪我的应用统计数据。我试着在http://java.dzone.com/articles/working-google-analytics-api上跟随一些人发布的教程，并说它对他们有用。这是我的密码：
我的应用程序跟踪程序。xml文件在下面
<?xml version="1.0" encoding="utf-8"?>
<resources
xmlns:tools="http://schemas.安卓.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>
我的global_tracker xml文件如下所示：
<?xml version="1.0" encoding="utf-8"?>
<resources
xmlns:tools="http://schemas.安卓.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>
在我的清单文件中，我输入了以下代码块：
<meta-data 安卓:name="com.google.安卓.gms.version"
安卓:value="@integer/google_play_services_version" />
我的主要活动如下：
import com.google.安卓.gms.analytics.GoogleAnalytics;
import com.google.安卓.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);
}
应用程序应该具有的MyApplication类如下所示
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);
}
}
当程序运行时，它到达行时崩溃
((MyApplication)getApplication()).getTracker(MyApplication.TrackerName.APP_TRACKER);
在主要活动中。我花了几个星期的时间试图找到一个解决这个问题的方法，但没有成功。有人能帮我在安卓项目中配置google analytics v4吗
我正在编辑这篇文章（因为我收到了同样的问题）&；这是logcat

第73行与op提到的使应用程序崩溃的行相同
注意：我正在emulator上测试它。此功能是否需要在实际设备上测试（已安装play store）

您需要在清单文件中添加应用程序名称
