android - AdMob 广告和 ErrorCode 无法解析为类型

Question

我已经添加了这段代码来查看应用程序无法接收广告时的错误。

    // Create an ad request. Check logcat output for the hashed device ID to
    // get test ads on a physical device.
    AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .addTestDevice("INSERT_YOUR_HASHED_DEVICE_ID_HERE")
        .build();

    // Start loading the ad in the background.
    adView.loadAd(adRequest);
 // Set AdListener
    adView.setAdListener(new AdListener() {
        @Override
        public void onFailedToReceiveAd(Ad ad, ErrorCode error) {
            System.err.println("Ad failed: " + ad.toString() + error.toString());    
        }

        @Override
        public void onReceiveAd(Ad ad) {
            System.out.println("Ad received: " + ad.toString());
        }
    });
  }

不幸的是，因为找不到 Ad 和 ErrorCode 可能是因为在最新的库中已经改变了一些东西。

我该如何解决这个问题？

根据 google admob 新的 api 服务

步骤:

1. 下载最新的 Google Play 服务库

2. BannerCodeActivity.java

   public class BannerCodeActivity extends Activity {
       private AdView mAdView;
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_banner_code_ad_listener);
   
           mAdView = new AdView(this);
           mAdView.setAdUnitId(getResources().getString(R.string.ad_unit_id));
           mAdView.setAdSize(AdSize.BANNER);
           mAdView.setAdListener(new ToastAdListener(this));
           RelativeLayout layout = (RelativeLayout) findViewById(R.id.mainLayout);
           RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
           RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
           layout.addView(mAdView, params);
           mAdView.loadAd(new AdRequest.Builder().build());
       }
   
       @Override
       protected void onPause() {
           mAdView.pause();
           super.onPause();
       }
   
       @Override
       protected void onResume() {
           super.onResume();
           mAdView.resume();
       }
   
       @Override
       protected void onDestroy() {
           mAdView.destroy();
           super.onDestroy();
       }
   }
   

3. 明确许可

   <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|smallestScreenSize"/>
