我正在将Google+登录集成集成到我的Android应用程序中。我正在学习本教程。 http://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/ 我按照每一步，但当我在我的Android设备上运行应用程序时，应用程序在启动屏幕后崩溃。
Log cat在应用程序中显示没有错误，但在Google Play服务库中显示错误。这是Log cat

如果我删除此代码并运行该应用程序。然后应用程序运行正常，但添加此代码后，应用程序在启动画面后崩溃。
任何帮助都将非常感谢...提前致谢

[[已解决]] 只需从addApi(Plus.API)方法中删除'null'作为参数即可解决错误
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).addApi(Plus.API)
.addScope(Plus.SCOPE_PLUS_LOGIN).build();
P.S请记住，您必须为您在Android设备中使用的电子邮件地址生成客户端ID作为主电子邮件地址。在我的案例中，这也对我有帮助。
