Question

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 services, does this imply that real devices with lower versions will not run my app?

the lowest version for my app is 2.3 and it worked until i use gps and polilyne to draw routes between markers. I found a Google play services out of date Requires 4132500 found 4131530 if a device with android version 2.3 got google play services 4132500 will my app work fine?

if it so, with the next updated versions of google play services - will my app still work?

What can i do to make my app work fine on most devices as posible?

Answer 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.
