Can't set ForwardNativeEventsToDalvik to true?

Hi,

Trying to implement Admob banners to my game, I've noticed that the banners weren't clickable. Apparently you have to set ForwardNativeEventsToDalvik to 'true' inside the manifest, but after I build the app, it automatically changes back to 'false'?

I've have three different AndroidManifest.xml and one AndroidManifest-main.xml, is this normal (even to have more than one)? I've tried setting ForwardNativeEventsToDalvik in all the files, but they all change back to false...?

Does anybody similar experiences or any clue what might causes this?

Any help will be appreciated!
