Google Play Services Version Issue Real Device

I´m new on android developement, and i have faced some troubles with google maps. here are a few questions I´know that adv with target 4.2 or higher includes google play service

Solution 1:

You just need to include google play services library into your project and Maps v2 will run on all devices having 2.3 and above.

Note: Those device which do not support google play services or glEsVersion version 0x00020000 will not be able to show maps. So, before loading map you must check that this device is supporting google play services or not. If not then you can show a message to user.
