AdMob Ad and ErrorCode cannot be resolved to a type

Question

I have added this code to see the error if App fails to receive ads.

    // 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());
        }
    });
  }

Unfortunately doesn't work because cannot find Ad and ErrorCode probably because in latest library have changed something.

How could I fix this?

Solution 1

As per google admob new api services

Step:

1. Download latest Google Play Services library

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. manifest permission

   <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"/>
   

You have to follow all this thing more information from here.

if any trouble then let me know.

I presume you mean that you are getting a compilation failure. NB posting an actual error message is always a good idea on StackOverflow.

Check your imports. If you are using the Google Play Services library for Admob then the package has changed to com.google.android.gms.ads

The interface for com.google.android.gms.ads.AdListener is

public abstract class AdListener {
  public void onAdLoaded();
  public void onAdFailedToLoad(int errorCode);
  public void onAdOpened();
  public void onAdClosed();
  public void onAdLeftApplication();
}

NB this has changed since Admob-6.4.1 You appear to be using the AdListener from Admob-6.4.1

Almost everything you need to know how to migrate to the new API is in this Google Play Services Migration document.

One thing it doesn't mention though, are the error codes values (that now are int values) for the new onAdFailedToLoad function that replaces the old onFailedToReceiveAd. These are described in the AdListener reference page and in the AdRequest reference page

have you entered this line <activity android:name="com.google.ads.AdActivity"</activity> in your Manifest?

[AndreaF]

Yes, but the error persist

[Harshid]

can you try my answer.

[AndreaF]

I use latest google-play-services.jar and the import are import com.google.android.gms.ads.AdListener; import com.google.android.gms.ads.AdRequest; import com.google.android.gms.ads.AdSize; import com.google.android.gms.ads.AdView; but unfortunately the object Ad seems missing

[William]

You appear to be using the AdListener from Admob-6.4.1. You need to be using the new AdListener which does not reference Ad or ErrorCode. See my updated answer.

[AndreaF]

Can you give me more details? How to print the error using the onAdFailedToLoad() and the new API that have no Ad object?

[William]

See developers.google.com/mobile-ads-sdk/docs/admob/intermediate‌​. The error code is one of 4 errors defined there. Ad never really was relevant and was pulled.

[AndreaF]

ok, but is unclear how to get the Ad info in my class since doesn't return anything and have no ad object where I can get the info with a toString. could you give me a sample? thanks

[William]

There is no Ad object anymore. I suggest you review your use case. Why do you need it?

[IgorGanapolsky]

@AndreaF Please review Google Play Services Migration for AdMob (developers.google.com/mobile-ads-sdk/docs/admob/play-migrat‌​ion). Then you will understand what people are talking about here when they're trying to help you.
