java - Connect to google api -

i have prograammed couple of years now, never made android app before, therefore build.gradle , manifest new me.

the app trying make app tests kids on multiplication table. app worked perfectly, tried add function log google , use achivements in google play, can't seem connect google api.

i have tried follow tutorial: tutorial, no luck. connectionresult{statuscode=sign_in_failed, resolution=null} whenever try connect. here manifest:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.nilsen.anders.multiplication" android:versioncode="2" android:versionname="1.0.1">  <uses-permission android:name="android.permission.internet"/> <uses-permission android:name="android.permission.get_accounts"/> <uses-permission android:name="android.permission.use_credentials"/>  <application      android:allowbackup="true"     android:icon="@mipmap/ic_launcher"     android:label="@string/app_name"     android:theme="@style/apptheme" >      <meta-data android:name="com.google.android.gms.games.app_id"         android:value="@string/app_name" />      <activity         android:name="com.example.andste569.multiplication.mainactivity"         android:label="@string/app_name" >         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>     <activity         android:name="com.example.andste569.multiplication.mainactivitymultipl"         android:label="@string/title_activity_main_activity_multipl"         android:screenorientation="portrait"         android:configchanges="orientation|keyboardhidden">     </activity> </application> 

and here gradle.build. not know sure if minyfy should enabled or not, i've tried both. buildscript copied example, not know does.

apply plugin: 'com.android.application'  android { compilesdkversion 21 buildtoolsversion "21.1.2"   defaultconfig {     applicationid "com.nilsen.anders.oblig_4"     minsdkversion 9     targetsdkversion 21     versioncode 2     versionname "1.0.1" } buildtypes {     release {         minifyenabled true         proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies { compile 'com.android.support:appcompat-v7:22.1.0' compile "com.android.support:support-v4:22.1.0" compile 'com.google.android.gms:play-services:7.0.0' compile filetree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:22.1.0' } buildscript {     repositories {     mavencentral()     } } 

i belive problem in manifest or gradle, , not in activity_main, because followed tutorial quite precisely, post code well.
