java - AndroidManifest.xml not working properly -

we sooooo close finishing our game, ready published through google play having problems making of game services work.

we have simple achievement button should call achievement ui, same goes logging in. not prompts when running on our android device.

we have

playgamesplatform.activate();

in our start function

 social.localuser.authenticate((bool success) => {      // handle success or failure  }); 

connected log in button

and

social.showachievementsui();

on our show achievement button.

our email connected tester on google play , game service api's enabled

my real question androidmanifest game play service unity created.

this it:

<?xml version="1.0" encoding="utf-8"?>  <!-- file automatically generated google play games plugin unity      not edit. --> <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 nearby connections api -->         <meta-data android:name="com.google.android.gms.nearby.connection.service_id"         android:value="" />      <!-- space in these forces interpreted string vs. int -->         <meta-data android:name="com.google.android.gms.games.app_id"             android:value="\ 606268116612" />          <meta-data android:name="com.google.android.gms.appstate.app_id"             android:value="\ 606268116612" />          <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" />     </application>  </manifest> 

i have read online package name should our package name shouldnt created when run android set using our id number our game? should physically change in code in manifest though says shouldnt edit it?
