java - GoogleAuthUtil.getToken Android 客户端 - Google Cloud Endpoints

Question

我在应用引擎中有以下实体

@Api(
        name = "profileendpoints", 
        version = "v1", 
        scopes = {EMAIL_SCOPE}, 
        clientIds = {ANDROID_CLIENT_ID, API_EXPLORER_CLIENT_ID, WEB_CLIENT_ID},
        audiences = {WEB_CLIENT_ID}
        )
public class ProfileEndPoints {
    ...
}

在 android 项目中，在 MainActivity 的 onCreate 方法中，我有 ff:

    settings = getSharedPreferences("profile", 0);
    credential = GoogleAccountCredential.usingAudience(this,
       "server:client_id:" + WEB_CLIENT_ID);

但是我得到了以下错误:

I/dalvikvm(477): Could not find method  
com.google.android.gms.auth.GoogleAuthUtil.getToken, referenced from method 
com.google.api.client.googleapis.extensions.android.gms.auth.GoogleAccountCredential.getToken
