Why can't I import the "common" part of Play Services com.google.android.gms.common.AccountPicker

Question

I am trying to import Google Play Services in order to use the AccountPicker. I followed the instructions, installed everything:

I also imported Play Services in my build.gradle file:

But the result is that I can definitely import com.google.android.gms but not com.google.android.gms.common http://developer.android.com/reference/com/google/android/gms/common/AccountPicker.html

I already tried to clean, rebuild,sync with Gradle, and delete the build folder.

Any idea what's going wrong?
