While Make sign APK of Google map (Failed to load map Could not contact Google servers) this error accured

In my application I will implement Google Maps example

However:

When I directly run the application the map will run perfectly
While I can make sign apk (make Key Store file and related to key Store Apk) then the map will not work

For this problem I am tried so many ideas like

Create an another and another API KEY of my app related to package
Put extra permission in Android Manifest File (latest Manifest permission are given below)

Can someone help?

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".CountryRequirement" >

<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />

</RelativeLayout>

My XML Layout contain this
I giving all permission that will need in Google Maps example

My manifest file:

Solution

Step for Making Google Map API Version 2

1)Creating the SHA-1 for your signature key.

The Eclipse debug key for signing your application can be found in the userhome/.android/debug.keystore file. eg) C:\Users\nil pc43.android\debug.keystore

    ----->  C:\Program Files\Java\jdk1.7.0_01\bin\keytool.exe -v -list -alias androiddebugkey -keystore "C:\Users\Info 1234\.android\debug.keystore" -storepass     
android -keypass android


    Example)
        C:\Program Files\Java\jdk1.7.0_01\bin>keytool.exe -v -list -alias androiddebugkey -keystore "c:\Users\nil pc43\.android\deb
        ug.keystore" -storepass android -keypass android
        Alias name: androiddebugkey
        Creation date: Apr 4, 2013
        Entry type: PrivateKeyEntry
        Certificate chain length: 1
        Certificate[1]:
        Owner: CN=Android Debug, O=Android, C=US
        Issuer: CN=Android Debug, O=Android, C=US
        Serial number: 4a5b5c6d
                Valid from: Thu Apr 04 18:33:13 IST 2013 until: Sat Mar 28 18:33:13 IST 2043
        Certificate fingerprints:
                 MD5:  51:CE:5C:07:05:31:98:6A:D5:7C:24:B1:B3:EC:22:A3
                 SHA1: B2:68:A7:D6:3A:FC:8F:15:8D:3E:1F:4A:E8:99:CE:8D:F5:28:07:4D
                 SHA256: 5B:5B:FE:7B:92:7F:06:53:1E:28:BB:D0:E5:CB:05:46:B0:81:76:CC:61:87:97:FA:19:68:B6:C1:08:E8:D6:D9
                 Signature algorithm name: SHA256withRSA
                 Version: 3

2)Register with the Google APIs Console

-----> https://code.google.com/apis/console/
     ----> Go to Services 
Then Activate(ON) the Google Maps Android API v2.

3)Create key for your application

-----> sELECT  API ACCESS
    **You need later to register your application via its package in this console together
    with the SHA-1 fingerprint of your signature key. For this you  select the entry and
    click on the API Access entry. Afterwards click on the Create new Android key...entry.**

-----> Click on "Create New Android KEY"
-----> Enter your SHA-1 fingerprint and the package of your application separated by a semicolon. 

       For example you can use the com.example.mymaps package. (your SHA-1 key;package Name)

4)Change Your Manifist.xml and JAVA File according below link

-----> please Reffer this Link
http://www.vogella.com/articles/AndroidGoogleMaps/article.html

5)Now Create new KeyStore File and APK file For your project.

----->C:\Program Files\Java\jdk1.7.0_01\bin>keytool -list -alias "your alias name" -keystore  "path that have keystor file of yor application"
    Enter keystore password: <pasword of your keystore>
    mapExample, Apr 18, 2013, PrivateKeyEntry,
    Certificate fingerprint (SHA1): 71:EF:B0:6A:A8:BG:E5:61:E9:23:D0:F2:1E:9D:D0:6F:A4:70:0F:A9

-----> Now you have new SHA-1 KEY 
-----> With this SHA-1 KEY, Follow the Step no 4

6)Now you will get NEW google map API KEY

Now use this key in to Manifeast.xml file (AS SHOWN IN STEM NO 4)

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="NEW GOOGLE MAP API KEY" />

7)Now Create New APK FILE of you APLICATION with the use the existing keystore.
