Google有一个关于移动设备分析数据的示例。代码在这里提供。我添加了jar文件，所有内容编译都很好，但是运行应用程序时出错了。 出于安全原因，我拿出了UA ID（不确定是否重要）
LogCat为我提供了以下信息： E / AndroidRuntime（1175）：java.lang.NoClassDefFoundError：com.google.android.apps.analytics.GoogleAnalyticsTracker 和的 E / AndroidRuntime（1130）：在com.google.android.apps.analytics.sample.TestActivity.onCreate（TestActivity.java:19）
从它的内容来看，它无法找到googleAnalyticTracker？但如果它编好了，为什么不能找到呢？
package com.google.android.apps.analytics.sample;
import com.google.android.apps.analytics.GoogleAnalyticsTracker;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class TestActivity extends Activity {
GoogleAnalyticsTracker tracker;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tracker = GoogleAnalyticsTracker.getInstance();
// Start the tracker in manual dispatch mode...
// tracker.startNewSession("", this);
// ...alternatively, the tracker can be started with a dispatch interval
// (in seconds).
tracker.startNewSession("", 20, this);
setContentView(R.layout.main);
Button createEventButton = (Button) findViewById(R.id.NewEventButton);
createEventButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
tracker.trackEvent("Clicks", // Category
"Button", // Action
"clicked", // Label
77); // Value
}
});
Button createPageButton = (Button) findViewById(R.id.NewPageButton);
createPageButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// Add a Custom Variable to this pageview, with name of "Medium"
// and value "MobileApp"
tracker.setCustomVar(1, "Medium", "Mobile App");
// Track a page view. This is probably the best way to track
// which parts of your application
// are being used.
// E.g.
// tracker.trackPageView("/help"); to track someone looking at
// the help screen.
// tracker.trackPageView("/level2"); to track someone reaching
// level 2 in a game.
// tracker.trackPageView("/uploadScreen"); to track someone
// using an upload screen.
tracker.trackPageView("/testApplicationHomeScreen");
}
});
Button quitButton = (Button) findViewById(R.id.QuitButton);
quitButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
Button dispatchButton = (Button) findViewById(R.id.DispatchButton);
dispatchButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// Manually start a dispatch, not needed if the tracker was
// started with a dispatch
// interval.
tracker.dispatch();
}
});
}
@Override
protected void onDestroy() {
super.onDestroy();
// Stop the tracker when it is no longer needed.
tracker.stopSession();
}
}

我更新了我的Android SDK后也遇到了同样的问题。我通过执行以下操作解决了这个问题：
右键点击您的项目 - ＆gt; Build Path - ＆gt; Configure Build Path - ＆gt;选择Order and Export标签 - ＆gt;查看GoogleAnalyticsJar.jar - ＆gt;按OK。
这有助于我解决问题。希望它也能帮助你。

在布局文件夹中创建alalytics.xml并粘贴以下代码。
<?xml version="1.0" encoding="utf-8" ?>
<resources>
<!--Replace placeholder ID with your tracking ID-->
<string name="ga_trackingId">UA-XXXX-Y</string>
<!--Enable automatic activity tracking-->
<bool name="ga_autoActivityTracking">true</bool>
<!--Enable automatic exception tracking-->
<bool name="ga_reportUncaughtExceptions">true</bool>
</resources>
Create Helper.java class and paste the following code.
import android.content.Context;
import com.google.analytics.tracking.android.EasyTracker;
import com.google.analytics.tracking.android.Fields;
import com.google.analytics.tracking.android.MapBuilder;
import com.google.analytics.tracking.android.Tracker;
import com.google.tagmanager.DataLayer;
import com.google.tagmanager.TagManager;
public class Helper{
/**
* Push an "openScreen" event with the given screen name. Tags that match that event will fire.
*/
private static Tracker tracker;
public static void pushOpenScreenEvent(Context context, String screenName) {
// Instantiate the Tracker
tracker = EasyTracker.getInstance(context);
tracker.set(Fields.SCREEN_NAME, screenName);
// Send a screenview.
tracker.send(MapBuilder
.createAppView()
.build()
);
}
/**
* Push an "Button clicked" event with the given screen name. Tags that match that event will fire.
*/
public static void pushbtnClickedEvent(Context context, String clickE) {
tracker = EasyTracker.getInstance(context);
// Values set directly on a tracker apply to all subsequent hits.
tracker.set(Fields.SCREEN_NAME, "Home Screen");
// This screenview hit will include the screen name "Home Screen".
tracker.send(MapBuilder.createAppView().build());
// And so will this event hit.
tracker.send(MapBuilder
.createEvent("UI", "click", "my btn clicked", null)
.build()
);
}
/**
* Push a "closeScreen" event with the given screen name. Tags that match that event will fire.
*/
public static void pushCloseScreenEvent(Context context, String screenName) {
// Instantiate the Tracker
tracker = EasyTracker.getInstance(context);
tracker.set(Fields.SCREEN_NAME, screenName);
// Send a screenview.
tracker.send(MapBuilder
.createAppView()
.build()
);
}
}
MainActivity.java
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import com.google.analytics.tracking.android.EasyTracker;
public class MainActivity extends Activity {
Button btnClickEvent;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnClickEvent=(Button)findViewById(R.id.button1);
btnClickEvent.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Helper.pushbtnClickedEvent(MainActivity.this, "Button Clicked");
}
});
}
@Override
protected void onStart() {
super.onStart();
EasyTracker.getInstance(this).activityStart(this);
Helper.pushOpenScreenEvent(this, "Main Activity");
}
@Override
protected void onStop() {
// TODO Auto-generated method stub
super.onStop();
EasyTracker.getInstance(this).activityStop(this); // Add this method
}
}
现在，您的应用程序已准备就绪，只需按“按钮”，然后打开您的Google分析仪表板。
不要忘记在manifest.xml中添加这些权限
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
