java - 不幸的是应用程序停止了: AdMob Error?

Question

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 站点的文档中给出的步骤(按原样复制并粘贴)进行操作。并在 eclipse ADT 中实现了他们的示例。它仍然无法工作......并且应用程序意外停止。

这里是 Activity _main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
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:id="@+id/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;
}

}

Answer 1

您的代码应该可以工作，没有问题。我认为，你没有将你的项目与谷歌提供的库集成。这篇文章可能对您有很大帮助:

https://developers.google.com/admob/android/eclipse#include_the_google_play_services_library

请严格按照步骤操作。
