The trick for me to get access to the full Play Store is to put a European sim in my phone (in this case a Samsung Galaxy) Be careful not to enable data traffic via mobile networks. 

Then using Wifi, create a VPN connection to somewhere not in China, and then you can get all the nice apps. It may be an advantage to also clear the data for the Play app prior to doing this. 

If you must have Google Play, you will need to "root" your phone and install another ROM in place of the stock one.  This isn't too difficult, but it may void your warranty.  But this isn't necessary if you simply want to install apps that are available in the Google Play Market.  These same apps are also available elsewhere.   There are many other alternative markets where you can download the files necessary to install almost all the programs that are in the Google Market.  Google is your friend.  Use it.  For more information about rooting your phone and access to some of the best modified ROMS, check out this site:  http://www.cyanogenmod.org/

Another option is to go to the Google Play website and download your applications/movies/etc... directly from there to your phone.  When I was in China this is how I did it and it didn't need a VPN to access.  However, it may need one now, I don't know.

Exactly it may favorably works for you....I guess you also have to check their public access for the better enhancement...Find Google apps shared contacts

Hmmm where did you get the Nexus 7?

I have a Nexus 10, my wife has a Nexus 4...all the Google stuff works.
