Displaying Admob Ads on Android

Question

I'm having problems displaying ads in an Android application. I'm not seeing ads even in test mode.

The layout is taken from admob's instructions, as below:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res/lgf.fourinarow"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

  <com.admob.android.ads.AdView 
      android:id="@+id/ad" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content"
      app:backgroundColor="#000000"
      app:primaryTextColor="#FFFFFF"
      app:secondaryTextColor="#CCCCCC"
      app:keywords="Android Game"
  />
</LinearLayout>

The mainfest is below:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="lgf.fourinarow"
    android:versionCode="1"
    android:versionName="1.0">
  <!-- Requires Android 2.1 or above -->
  <uses-sdk android:minSdkVersion="7" />
  <application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".LGFFourInARow">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
    </activity>
    <!-- Track Market installs --> 
    <receiver android:name="com.admob.android.ads.analytics.Inst allReceiver" android:exported="true">
      <intent-filter>
        <action android:name="com.android.vending.INSTALL_REFERRER " />
      </intent-filter>
    </receiver>

    <!-- The application's publisher ID assigned by AdMob -->
    <meta-data android:value="xxxxxxxxxxxxxx" android:name="ADMOB_PUBLISHER_ID"/>
  </application>
  <!-- AdMob SDK permissions -->
  <uses-permission android:name="android.permission.INTERNET" />
</manifest> 

(I have my real publisher id in my code) In my Java code, I have included AdManager.setTestDevices(new String[] { AdManager.TEST_EMULATOR } ); in the onCreate section, to enable test mode. I've also added log messages in the onFailedToReceiveAd , onFailedToReceiveRefreshedAd , onReceiveAd and onReceiveRefreshedAd functions. However I have still ever seen and ad, and can't see any output in the log cat. Can anyone suggest what else I should be doing?

Answer 1

您需要其权限ACCESS_NETWORK_STATE。

Answer 2

Try putting Internet permission before the <application> tag in the manifest.

    <!-- AdMob SDK permissions -->
    <uses-permission android:name="android.permission.INTERNET" />
  </application>
</manifest>

Also, have you verified that you can load a web page in the browser? Sometimes the emulator has DNS problems.
