Contribution expected

Ok guys, girls
If you want to enhance the project you can help:

1. Not all the parameter of the request have been coded
2. There is no check of the google server response code
3. We can do the same for the NearbyRestApi
4. And a lot of others stuff
   From my point of view, I will let it like it is, it's enough to show how to do and to make small application. And to be perfectly honest, I haven't the time to do it.
   So contributors expected :)
