About Get google services [duplicate]

Since Android 4.2.2 it's possible to run Google Services on the Android Emulator. I'm currently making an Android app and made a test project to see if I can get Google+ sign-in and sign-out to work.
I've followed the following tutorial:
http://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/
With extra info used from the following tutorials/sites:
https://developers.google.com/+/mobile/android/getting-started
https://developers.google.com/+/mobile/android/sign-in
http://developer.android.com/google/play-services/setup.html#Setup
This generated the following code:

The other steps I did were:
At https://console.developers.google.com/project I've created a project with:
Google+ API on:
And a Client ID created with the correct SHA1 and exact same namespace as the project:
At Eclipse:
I've installed the google-play-services library:
And added it to the project:
I've also created an Emulator with version 4.4.2:
But when I run the app I get the following error, and this error keeps popping up when I click on the button:
Anyone has any idea where it goes wrong? Thanks in advance for the responses.

Ok, after trying some things it turned out I had one last option not correctly checked, which wasn't mentioned anywhere in the tutorial(s)..
Instead of Android 4.4.2 as Project Build Target & Emulator Target, I've selected Google APIs 4.4.2. Now I don't get the error of Google Play services anymore.
I do get a NullPointerException though, but at least I can continue.. ;)
EDIT: Fixed the NullPointerException and modified the code in my original post. Everything works as it should now and I hope this post helps other people with the same (or other) errors using google play services sign-in using an Android Emulator.

Try using the Goole APIs API level 19 as emulator target instead of normal API level 19.

What should I put on imeActionId?

I want to create app using Android Studio Login Activity. It said that #+id/login in attribute imeActionId is not a valid integer. What happened? I didn't change anything.It's 'android:imeActionId="#+id/login"' by default.
