Google +登录：无法启动

我在我的项目中使用了com.actionbarsherlock.app.SherlockActivity。当我尝试开始另一项活动时，我需要进行Google+登录，则会发生此错误。我在实际设备上收到此错误，而不是仿真器。你觉得我做错了什么？Google +登录：无法启动

错误

        mPlusClient.connect();

      }

    }

我也尝试使用“setScopes（Scopes.PLUS_LOGIN）”，但遇到同样的问题。

import com.google.android.gms.common.Scopes; 
// in onCreate() 
mPlusClient = new PlusClient.Builder(this, this, this).setScopes(Scopes.PLUS_LOGIN).build();

我试着开始keytool以及....是androiddebugkey需要？ https://developers.google.com/+/mobile/android/getting-started

C:\repos>c:\java\jdk1.6.0_34\bin\keytool.exe -exportcert -alias androiddebugkey -keystore agoyal-release-key.keystore -list -v 
Enter keystore password: 
keytool error: java.lang.Exception: Alias <androiddebugkey> does not exist

**“我在做什么错了？”**那么你做错的第一件事就是你没有向我们展示你的所有代码。问题出在'com.google.android.gms.plus.activity.AccountSignUpActivity'上。假设你试图从你的'SignInActivity'开始，那么你只会显示'/ * code * /'。 – Squonk 2013-05-12 23:31:58

Squonk：我已经共享了SignInActivity.java中的所有代码 – AG1 2013-05-12 23:54:19

从logcat中，我同意@Squonk，有一些代码丢失！ – thiagolr 2013-05-29 02:23:12

的keytool命令，如果你使用自己的释放键，别名应该使用一个密钥，而不是“androiddebugkey”。

感谢为此 - 我不知道为什么谷歌不澄清，在他们的文档... – bkurzius 2014-02-04 00:09:40

东西不对，你确定这是正确的logcat输出吗？

用你的代码，你应该得到android.app.SuperNotCalledException: Activity {LandingActivity} did not call through to super.onCreate()异常，而不是你显示的错误。

另外，SignInActivity中的public onConnected()方法有不正确的签名。正确的应该是public onConnected(Bundle connectionHint)。这很可能是您的应用程序编译不正确。
