I have been trying to implement a sample application in order to study the working of Google maps API. I have been struck with the configuration itself. I can't seem to run the application.
Here's my code at Github :-
https://github.com/siva54/SampleMapApplication
And here's my logcat :-

Would you please help? Thanks in advance.
It looks like it's not finding the Google Maps classes at runtime. Are you running this on a device or an emulator because you can't use Google Maps v2 on an emulator at this time.
If you are running on a device then make sure you have Google Play Services installed. It contains the runtime for Google Maps v2.

Solved my Problem. The issue occurred because even though I i referenced the google play library, The reference is not considered by eclipse and it was shown by a cross mark. I have resolved that with the help of the following stackoverflow post:-
In eclipse, unable to reference an android library project in another android project
