Unity android leaderboard login

Question

I am very first time implementing the google leaderboard in one of the android games developed on Unity platform. I think i did everything right (according to some tutorial i was following) but when i try to login into the google game play services i get the following exception " Using Google Play games services requires a metadata tag with the name "com.google.android.gms.games.APP_ID" in the application tag of your manifest. Missing metadata tag with the name "com.google.android.gms.appstate.APP_ID" in the application tag of your manifest." While the metadata tag is there

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.google.example.games.mainlibproj"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16" />

<application>

 <!-- 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="\ 686*********" />

    <!-- Keep track of which plugin is being used -->
    <meta-data android:name="com.google.android.gms.games.unityVersion"
        android:value="\ 0.9.41" />

    <!-- Build time check to make sure play-services libraries are present -->
    <meta-data android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
</application>

What can be the problem here?

I got the solution after struggling for two days, it was a bug of GooglePlayGamesPlugin-0.9.41.unitypackage while after downgrading to version 0.9.38a it worked as expected.
