Using boolean in your Android.manifest ?

It's a very old post but maybe useful to some one

Basically you can specify which xml file you gonna look up in your Android Manifest
in res/values/bools.xml

 <resources>  
 <bool name="hasHoneycomb">false</bool>  
 </resources>  

in res/values-v11/bools.xml

 <resources>  
 <bool name="hasHoneycomb">true</bool>  
 </resources>  

finally in AndroidManifest.xml

 <receiver android:name=".WidgetProvider" android:enabled="@bool/hasHoneycomb">  
 <intent-filter>  
 <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />  
 </intent-filter>  
 <meta-data android:name="android.appwidget.provider"  
 android:resource="@xml/widgetinfo"/>  
 </receiver>
