After updating to Android Studio 2.3 cannot resolve symbol GoogleAccountCredential

Question

After updating from Android Studio 2.2 to 2.3 the editor shows an error claiming that these classes cannot be resolved:

import com.google.api.client.googleapis.extensions.android.gms.auth.GoogleAccountCredential;
import com.google.api.client.googleapis.extensions.android.gms.auth.GooglePlayServicesAvailabilityIOException;
import com.google.api.client.googleapis.extensions.android.gms.auth.UserRecoverableAuthIOException;

Building still works which is strange. I'm using the Gradle default wrapper and project's build.gradle references:

classpath 'com.android.tools.build:gradle:2.3.0'

Any thoughts?

Answer 1

I meet the same question these classes cannot be resolved after the Android studio updates from 2.2 to 2.3.

import android.support.v7.app.ActionBar; import android.support.v7.app.AppCompatActivity;

The Gradle plugin and Gradle version setting.

Try syncing the project, click Tools -> Android -> Sync Project with Gradle Files. It fix my problem.
