GoogleAuthUtil cannot be resolved

问题

I am using Google Play Service's Authorization with GoogleAuthUtil in my Android applcation. I did this part about 2 months back, its been working perfectly fine then onwards. Yesterday, I updated the SDK. Now I am getting this error in my application. It says "GoogleAuthUtil cannot be resolved".
Has anything changed in the updated SDK?
How can I solve this?

I am importing the following:

import com.google.android.gms.auth.GoogleAuthException;
import com.google.android.gms.auth.GoogleAuthUtil;
import com.google.android.gms.auth.GooglePlayServicesAvailabilityException;
import com.google.android.gms.auth.UserRecoverableAuthException.

I am getting

com.google.android.gms.auth cannot be resolved.

Whenever you update any library make sure to first remove it from your references and again add it to your references. After that clean the project. Restart Eclipse if needed. And I feel then you are good to go!! :)

Just remove the <uses-library> tag from your AndroidManifest.xml and restart and clean everything. For sure it will start running.

If you are using Android Studio follow step below.

1. Open SDK Manager -> SDK Tool -> click on Google Play service and Apply
2. Open Module Setting or Project Structure -> on Dependencies tab click on + button -> select 1.Library Dependency ->Select play-services (...) then click OK
3. Clean your project by Build -> Clean Project
