AdMob can't display ads because of configChanges [duplicate]

Admob Error in Eclipse for android:configChanges

I want to display AdMob's ads in my android application. I do all the necessary like in the doc. But I can't run my app because there is an error on my AndroidManifest.xml on this line :

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

The error is :

error: Error: String types not allowed (at 'configChanges' with value 'keyboard|keyboardHidden|orientation|  screenLayout|uiMode|screenSize|smallestScreenSize'). 

But if I delete some value my app is running but instead of the ads I've this text : "You must have AdActivity declared in AndroidManifest.xml with configChanges."

I don't unterstand how I can fix the problem.

I'm using android SDK 2.1 and the last google adMob SDK 4.3.1

Thanks

To fix the problem you have to set your project build target to Android 3.2 or higher, see the requirements section in the documentation (Android tab).
