Unity Admob Banner is not clickable.

Hello,

I'm developing an Android game with Unity. I used this plugin for Admob. The Interstitial ad is clickable but when i click the banner nothing's happen. I tried this but nothing's changed. Additionally, i tried add com.unity3d.player.UnityPlayerNativeActivity Activity in manifest file and i get this error:

Error building Player: CommandInvokationFailure: Unable to merge android manifests. See the Console for more details. C:\Program Files (x86)\Java\jdk1.8.0\bin\java.exe -Xmx1024M -Dcom.android.sdkmanager.toolsdir="C:/Program Files (x86)/Android/android-sdk\tools" -Dfile.encoding=UTF8 -jar "C:/Program Files (x86)/Unity/Editor/Data/BuildTargetTools/AndroidPlayer\sdktools.jar" - stderr[ Error: [Temp\StagingArea\AndroidManifest-main.xml:4, C:\Users\UĞUR\Documents\DefendTheCore\Temp\StagingArea\android-libraries\MainLibProj\AndroidManifest.xml:15] Trying to merge incompatible /manifest/application/activity[@name=com.unity3d.player.UnityPlayerNativeActivity] element: -- -- ++ ] stdout[ ]

How can i solve this problem? Any suggestions will make me happy. Thanks.

Here is my manifest file:
