I am playing with the Google sample app relative to the Google Plus SDK (sample app provided by Google here: https://developers.google.com/+/quickstart/android)
I can run the sample app. But when I want to login to Google Plus from within the app, I get the message: "This app won't run unless you update Google Play Services". If I click on the update button, I see that I have got the last update of the Google Play Services (v3.2.66). In Eclipse, I have got rev. 13 of Google Plus SDK.
How can I solve this problem?
