Android Admob build error: Trying to merge incompatible

Hi,

I'm getting an error when I try to make an android build.

 Error: [Temp/StagingArea/AndroidManifest-main.xml:4, /Desktop/Unity Project/Temp/StagingArea/android-libraries/google-play-services_lib/AndroidManifest.xml:6] Trying to merge incompatible /manifest/application/activity[@name=com.unity3d.player.UnityPlayerNativeActivity] element:
 
 UnityEditor.HostView:OnGUI()

 Error building Player: CommandInvokationFailure: Unable to merge android manifests. See the Console for more details.

 ++    @android:label="@string/app_name"

 ]

I have the Admob package imported and the google-playservices_lib folder in the the Plugins/Android directory, also using Unity 4.6.9f1

I'm not sure how to go about fixing this issue, any help would be great.

Thanks
