after immigrating my admob to Google Play Services. I always get this error code
AdRequest.ERROR_CODE_NO_FILL
Here is the explanation:
ERROR_CODE_NO_FILL The ad request was successful, but the ad was not received due to lack of advertising resources.
And I think it was implemented successfully, and I have been waiting for so long (3 days), but there are no ads instead instead of empty space TT

Here are my code details:
<LinearLayout
android:id="@+id/ad_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
</LinearLayout>
adLayout = (LinearLayout) view.findViewById (R.id.ad_layout);
adView = new AdView(getActivity());
adView.setAdUnitId(Config.AD_PUBLISH_KEY);
adView.setAdSize(AdSize.SMART_BANNER);
adLayout.addView(adView);
AdRequest adRequest = new AdRequest.Builder()
.build();
adView.loadAd(adRequest);
03-09 12:46:50.765: I/Ads(2453): Use AdRequest.Builder.addTestDevice("28F0E937BC5EDD2ED24E3F7540AE8251") to get test ads on this device.

03-09 12:46:51.265: W/Ads(2453): Failed to load ad: 3
It looked good, but the ad didn't return, but when I extracted the Admob code for a new clean Android project, it worked fine , I think this is a configuration problem, any help is much appreciated: D
