AdMob不顯示

Question

我已經在AdMob上註冊，並收到應用程序ID，所以廣告假設出現在activity_main.xml中，但它只是需要空間，而不顯示這裏的任何東西是activity_main.xml中

代碼

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
      xmlns:app="http://schemas.android.com/apk/res-auto" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      xmlns:tools="http://schemas.android.com/tools" 
      xmlns:ads="http://schemas.android.com/apk/res-auto" 
      tools:context="com.android.homeexercises.MainActivity" 
      > 
<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    android:background="#0000" 
    > 
<com.google.android.gms.ads.AdView 
     android:id="@+id/adView" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     ads:adSize="BANNER" 
     ads:adUnitId="@string/banner_ad_unit_id"> 
    </com.google.android.gms.ads.AdView> 

</LinearLayout> 
</ScrollView> 

代碼在MainActivity類別：在清單

@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); 
    } 

代碼：

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
      package="com.afai_aapps109.android"> 

    <application 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher" 
     android:label="@string/app_name" 
     android:roundIcon="@mipmap/ic_launcher_round" 
     android:supportsRtl="true" 
     android:theme="@style/AppTheme" 
     > 

     <meta-data android:name="com.google.android.gms.version" 
        android:value="@integer/google_play_services_version" /> 
     <activity android:name="com.android.homeexercises.MainActivity"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN"/> 

       <category android:name="android.intent.category.LAUNCHER"/> 
      </intent-filter> 
     </activity> 
     <activity android:name="com.google.android.gms.ads.AdActivity" 
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" 
        android:theme="@android:style/Theme.Translucent" /> 
    </application> 

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

，並在圖書館gradle：

compile 'com.google.android.gms:play-services:11.0.0'
