Question

我按照本教程了解了如何添加AdView

https://developers.google.com/mobile-ads-sdk/docs/

将此添加到我的AndroidManifest.xml：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<meta-data android:name="com.google.android.gms.version"
 android:value="@integer/google_play_services_version"/>

<activity android:name="com.google.android.gms.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|sm    allestScreenSize"/>

这是build.gradle

dependencies {
compile 'com.android.support:appcompat-v7:+'
compile 'com.google.android.gms:play-services:4.0.30'
}

到我的java文件：

import com.google.android.gms.ads.*;


public class admob extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.admoblayout);


    // Create an ad.
    AdView adView = new AdView(this);
    adView.setAdSize(AdSize.BANNER);
    adView.setAdUnitId("My_UnitID_Here");

    RelativeLayout layout = (RelativeLayout) findViewById(R.layout.admoblayout);
    layout.addView(adView);


    AdRequest adRequest = new AdRequest.Builder().build();
    adView.loadAd(adRequest);
}

}

但每当我打开活动时它都会崩溃

logcat：

FATAL EXCEPTION: main java.lang.NoClassDefFoundError: com.google.android.gms.ads.AdView

有时，在添加新布局甚至修改现有布局时，IDE需要刷新项目才能生效。

刷新/重建项目后，您应该好好去。
