不幸的是，该应用程序已停止：AdMob错误？

The following classes could not be instantiated: - com.google.android.gms.ads.AdView (Open Class, Show Error Log) : AdMob

我已按照开发人员admob站点文档中给出的步骤进行操作（复制并粘贴原样）。并已在eclipse ADT中实现了他们的示例。它仍然无法正常工作，并且应用程序意外停止。

这是activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

<com.google.android.gms.ads.AdView

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignParentBottom="true"
    ads:adSize="BANNER"
    ads:adUnitId="@string/banner_ad_unit_id">
</com.google.android.gms.ads.AdView>

</RelativeLayout>

----- MainActivity.java -----

package com.google.android.gms.example;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    AdView mAdView = (AdView) findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

您是否已将Google Play服务库作为项目导入？

将google-play-services_lib导入为项目很重要：Select File > Import > Android > Existing Android Code Into Workspace然后单击“下一步”。选择浏览...，输入[android-sdk-folder]/extras/google/google_play_services/libproject/google-play-services_lib，然后单击完成。（请参阅“示例代码”下的https://developers.google.com/maps/documentation/android/intro），然后按照链接的答案中的说明进行操作：

导入“ google-play-services_lib”项目的实际来源，并将其链接为> Android库。

通过Project-> Properties-> Android-> Library，添加-> google-play-services_lib（您可以右键单击您的项目并选择Properties，然后选择Android）来执行此操作。

不要通过您的项目的“ Java Build Path”将其添加为从属项目，这对我不起作用。
