Google AdMob载入广告

Question

currently I am trying to load ads into my application. I have followed the guide and this is what i've gotten:

AndroidManifest.xml

<!-- Include required permissions for Google Mobile Ads to run-->
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:largeHeap="true"
    android:hardwareAccelerated="true"
    android:isGame="true"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <meta-data android:name="com.google.android.gms.games.APP_ID"
        android:value="@string/app_id" />
    <meta-data android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version"/>

   ...

    <!--Include the AdActivity configChanges and theme. -->
    <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>

I've added the AdView like so:

<com.google.android.gms.ads.AdView
    android:id="@+id/ad_banner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    ads:adSize="BANNER"
    ads:adUnitId="@string/ad_banner_id"
    />

And finally the the code to load the ad:

adView = (AdView) m.findViewById(R.id.ad_banner);
AdRequest req = new AdRequest.Builder().addTestDevice("my device id").build();
adView.loadAd(req);

Now the code seems to be alright but when I run it I get the following logcat output:

E/GmsClient﹕ unable to connect to service: com.google.android.gms.ads.service.START

W/Ads﹕ There was a problem getting an ad response. ErrorCode: 0
W/chromium﹕ [WARNING:data_reduction_proxy_settings.cc(328)] SPDY proxy OFF at startup
W/art﹕ Attempt to remove local handle scope entry from IRT, ignoring
W/AwContents﹕ onDetachedFromWindow called when already detached. Ignoring
W/art﹕ Attempt to remove local handle scope entry from IRT, ignoring
W/art﹕ Attempt to remove local handle scope entry from IRT, ignoring
W/Ads﹕ Failed to load ad: 0

And then nothing displays where the ad should be. Anyone know what I'm doing wrong and why the previous errors are coming up? Thanks.

EDIT: I tried it on a different device (Nexus 4 running 5.1) and the ads seemed to work. But it they don't on my Nexus 5 running 5.0.1

Answer 1

Maybe you don't have latest version of Google Play Services library.

Answer 2

This happened to by my phones fault. An application was secretly blocking the google play service ad services. I just had to disable this and it was fine, so nothing wrong with the code.
