내가 짖는 소리를 사용하고 있습니다 :

public class MenuActivity extends Activity { 
    AdView adView ; 
    @Override 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     AdView ad = (AdView) findViewById(R.id.adView); 
AdRequest request = new AdRequest(); 
ad.loadAd(request); 

을 그리고 내 매니페스트 안의 내용 :

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

그러나 어디에서 문제가 있는지 알 수 없습니다. 내가 해결책을 많이 봤어

Answer 1

ad.loadAd(request);에있는 경우 이는 activity_main 레이아웃에없는 id와 관련된 문제 일 수 있습니다.

어쩌면 AdRequest의 초기화에 문제가있을 수 있습니다. 아마도 이러한 요소 중 하나가 null 인 이유를 확인할 수 있습니다. 당신이 그 중 어떤 것이 null인지 알게되면 문제를 해결하려고 할 수 있습니다.
