And the main manifest here (Copy and paste the manifiest from temp folder and added the (<meta-data android:name=“unityplayer.ForwardNativeEventsToDalvik” android:value=“true” ) for admob implementation .

<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="preferExternal" android:versionCode="8" android:versionName="1.2" package="com.TreSSor.MinimalSnake">
  <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" android:xlargeScreens="true"/>
  <application android:debuggable="true" android:icon="@drawable/app_icon" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
    <activity android:label="@string/app_name" android:name="com.unity3d.player.UnityPlayerActivity">

        <category android:name="android.intent.category.LAUNCHER"/>
      </intent-filter>
      <meta-data android:name="unityplayer.UnityActivity" android:value="true"/>
      <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="true" />
    </activity>
    <!-- Google Mobile Ads Activity -->
    <activity android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" android:name="com.google.android.gms.ads.AdActivity"/>
    <!-- InAppPurchase Activity -->
    <activity android:name="com.google.android.gms.ads.purchase.InAppPurchaseActivity" android:theme="@style/Theme.IAPTheme"/>
    <!-- Denote the referenced Google Play services version -->
    <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>

        <activity android:name="com.google.games.bridge.NativeBridgeActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"/>

     <!-- Required for Nearby Connections API -->
        <meta-data android:name="com.google.android.gms.nearby.connection.SERVICE_ID" android:value=""/>

        <!-- the space in these forces it to be interpreted as a string vs. int -->
        <meta-data android:name="com.google.android.gms.games.APP_ID" android:value="\ "/>
        <meta-data android:name="com.google.android.gms.appstate.APP_ID" android:value="\ "/>

  </application>
  <uses-sdk android:minSdkVersion="9" android:targetSdkVersion="23"/>
  <!-- Google Mobile Ads Permissions -->

  <uses-permission android:name="com.android.vending.BILLING"/>
</manifest>

In the file GoogleMobileAdsPlugin/AndroidManifest.xml, take out the line:

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

Seems as though this gets added into the final manifest anyway. This fixed my problem, now the manifests merge.
