i get the URL but cant show it.

in manifest:

    <activity android:name="com.google.ads.AdActivity"
              android:configChanges="keyboard|keyboardHidden|orientation"/>
  </application>
  <uses-permission android:name="android.permission.INTERNET"/>
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

in .java:

    // Create the adView
    AdView adView = new AdView(this, AdSize.BANNER, MY_AD_UNIT_ID);
    // Lookup your LinearLayout assuming it’s been given
    // the attribute android:id="@+id/mainLayout"
    RelativeLayout layout = (RelativeLayout)findViewById(R.id.rlayout);
    // Add the adView to it
    layout.addView(adView);
    // Initiate a generic request to load it with an ad
    AdRequest r = new AdRequest();
    r.setTesting(true);
    r.addTestDevice("*****************************");

    adView.loadAd(r);

解决方案

The /etc/hosts file on your phone has aliased r.admob.com to 127.0.0.1. I had this occur when I used a flashed ROM on my phone -- the ROM defined a whole bunch of entries like that so I'd never get ads. Which was great until I was testing my own ad-enabled app :-)

Edit your /etc/hosts and take out that entry.
