Admob ads not displayed on android 1.6

Question

i have an app that runs perfectly on android 1.6+, but admob ads are not displayed only in 1.6 version.

<activity android:name="com.google.ads.AdActivity"  
      android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>

Project build target: android 3.2

I've tried many options without any success.

adb logcat
