Answer 1

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

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.
