Google maps V2 - Authorization failure, I can't display map

Question

I'm trying display a map on my app but I can't display, I's impossible for me...

My steps:

1. Install "Google play services" from SDKManager.

2. Add library from Project

build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "prueba.mapas.alvaro.myapplication"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'com.google.android.gms:play-services:6.5.87'
}

Add Library to AndroidManifest.xml too.

Manifest (part)

 <application

......
<meta-data android:name="com.google.android.gms.version"
                   android:value="@integer/google_play_services_version" />

......

 </application>

3. Get SHA1

4. Go to "https://code.google.com/apis/console/b/0/?noredirect" ato get API Key.

• Package name on Android Studio

5. Modify AndroidManifest.xml with permissions.

   <permission
       android:name="prueba.mapas.alvaro.permission.MAPS_RECEIVE"
       android:protectionLevel="signature"/>
   <uses-permission android:name="prueba.mapas.alvaro.permission.MAPS_RECEIVE"/>
   <uses-permission android:name="android.permission.INTERNET"/>
   <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
   <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
   <!-- The following two permissions are not required to use
        Google Maps Android API v2, but are recommended. -->
   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
   
   <uses-feature
       android:glEsVersion="0x00020000"
       android:required="true"/>
   
   <application
       android:allowBackup="true"
       android:icon="@drawable/ic_launcher"
       android:label="@string/app_name"
       android:theme="@style/AppTheme" >
       <activity
           android:name=".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>
   
       <meta-data android:name="com.google.android.gms.version"
                  android:value="@integer/google_play_services_version" />
   
       //api key
       <meta-data
           android:name="com.google.android.maps.v2.API_KEY"
           android:value="AIzaSyD1UolEb1tDMe6qB5BUF5orFzc3CDtvJYg"/>
   
   </application>
   

6. Create my Layout map_activity.xml

7. Create my principal class MainActivity.class

   public class MainActivity extends ActionBarActivity {

       @Override
   
       protected void onCreate(Bundle savedInstanceState) {
   
           super.onCreate(savedInstanceState);
           setContentView(R.layout.map_activity);
   
           MapFragment mapFragment = (MapFragment) getFragmentManager()
                   .findFragmentById(R.id.map);
       }
   }
   

8. Connect my Device and it's reports that error and on my device always appear White screen.

NOTE: ALWAYS I CLEAR DATA FROM MY APP ON MY DEVICE, UNISTALL AND INSTALL AGAIN, NOT WORKS

UPDATE

I have enable Google Maps V2 on console

Any suggestions?

UPDATE - SOLUTION

Solved, I put on the Manifest the "Key for browser apps (with referers)" instead of the "Key for Android apps (with certificates)" from the Google API Console

I checked your code. Sounds like well. But try this .

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/iqamah_map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.SupportMapFragment" />

Use FragmentActivity

 public class YourActivity extends FragmentActivity {

   GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_activity);
        map =((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.iqamah_map)).getMap();

    }
}

Update your build.gradle

  compile 'com.google.android.gms:play-services:5.0.89'
