And what is the minimum google play service version that this api could work?

回答1:

You can use this for checking version

GoogleApiAvailability.GOOGLE_PLAY_SERVICES_VERSION_CODE

I think, first you should check, if service is available ?

public int isGooglePlayServicesAvailable (Context context)

Google Doc

How to know GPS version of your phone?

If manually, go to Settings > Applications > Google Play Services.

If programatically, follow the answer in this SO thread:

int v = getPackageManager().getPackageInfo("com.google.android.gms", 0 ).versionCode;

What is the minimum google play service version for this API?

Minimum Android version required is Android 2.3 (Gingerbread).
