这个项目几乎与admob页面上的例子非常相似,但它仍然不起作用! 这是我的班级文件:
package com.firecow.admobtest;
import com.google.ads.AdRequest;
import com.google.ads.AdSize;
import com.google.ads.AdView;
import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
/**
* A simple {@link Activity} that embeds an AdView.
*/
public class AdMobTesterActivity extends Activity {
/** The view to show the ad. */
private AdView adView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Create an ad.
adView = new AdView(this, AdSize.BANNER, "a14fd022edb48e8");
// Add the AdView to the view hierarchy. The view will have no size
// until the ad is loaded.
LinearLayout layout = (LinearLayout) findViewById(R.id.mainLayout);
layout.addView(adView);
// Create an ad request. Check logcat output for the hashed device ID to
// get test ads on a physical device.
AdRequest adRequest = new AdRequest();
adRequest.addTestDevice(AdRequest.TEST_EMULATOR);
// Start loading the ad in the background.
adView.loadAd(adRequest);
}
/** Called before the activity is destroyed. */
@Override
public void onDestroy() {
// Destroy the AdView.
if (adView != null) {
adView.destroy();
}
super.onDestroy();
}
}
......和我的清单:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />
</LinearLayout>
我不知道该怎么做,我只在logcat中得到这个错误
java.lang.NoClassDefFoundError: com.google.ads.AdView
这是什么意思?请帮忙!

您需要在项目中加入AdMob SDK。如果您正在使用Eclipse,this tutorial将向您展示如何执行此操作。
如果您还没有下载SDK,可以从AdMob控制面板或here执行此操作。
最后,检查您的AndroidManifest.xml
文件。它应该添加在同一个教程中加粗的代码行。 (旁注:你向我们展示了你的布局文件,而不是你的清单。)
此外,请确保在完成此操作后清理并重建了项目。

确保已将admob.jar复制到libs文件夹中,并且不要忘记在Menifest.xml中添加admob活动标记
<activity
android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" >
</activity>
