            }
        }
    }
    }

I have removed most other markers and related code to accommodate the size.

When you change the package name make sure that a new key is generated and the new key is copied to the android manifest since to display maps a key with the package name is used.

EDIT

You are missing <uses-library android:name="com.google.android.maps" /> and use

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

in your xml file to display map

New key has been generated...still no luck – Suresh PB Apr 08 '14 at 10:10
No error. Default map is rendered without any markers – Suresh PB Apr 08 '14 at 11:17
How did you change the package name?? – Lal Apr 08 '14 at 11:18
In eclipse project explorer clicked on src-package and re factored to new package name. Added manifest for reference – Suresh PB Apr 08 '14 at 11:48
I'm unclear about your edit. do you want me to replace instead of android:name="com.google.android.gms.maps.MapFragment" – Suresh PB Apr 09 '14 at 03:45
Last evening, I tried to connect my phone and connected the phone to the wifi. On the eclipse, I ran the application to the phone. It worked as expected without any edit. Now, without the wifi also it works. No changes were made, but it worked. The same when downloaded from play.google.com errors out saying "MainActivity" is not present. I'm confused. – Suresh PB Apr 09 '14 at 03:48
Did you list the activity within your AndroidManifest.xml file? – Lal Apr 09 '14 at 05:40
Acitivity has been listed, also listed the parent activity attribute. – Suresh PB Apr 09 '14 at 05:45

Try this link

or

Might be helpfull..

Try going to Project -> Properties -> Java Build Path -> Order & Export and ensure Android Private Libraries are checked for your project and for all other library projects you are using. Clean all projects afterwards and see what happens.
