Android 谷歌+；登录：活动赢得'；开始

我在项目中使用com.actionbarsherlock.app.SherlockActivity。当我尝试启动另一个需要进行Google+登录的活动时，会发生此错误。我在实际的设备上，而不是在模拟器上得到这个错误。你认为我做错了什么

我也尝试过使用“setScopes（Scopes.PLUS_LOGIN）”，但遇到了同样的问题

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

我也试着启动keytool。。。。是否需要androiddebugkey

C:\repos>C:\java\jdk1.6.0\u 34\bin\keytool.exe-exportcert-alias androiddebugkey-keystore agoyal-release-key.keystore-list-v
输入密钥库密码：
keytool错误：java.lang.Exception:别名不存在
java.lang.Exception:别名不存在
位于sun.security.tools.KeyTool.doPrintEntry（KeyTool.java:1339）
位于sun.security.tools.KeyTool.doCommands（KeyTool.java:869）
运行（KeyTool.java:172）
位于sun.security.tools.KeyTool.main（KeyTool.java:166）

对于keytool命令，如果您使用自己的释放密钥，别名应该是您使用的密钥，而不是“androiddebugkey”。

有些不正确，您确定这是正确的logcat输出吗

使用代码，您应该得到

android.app.SuperNotCalledException:Activity{LandingActivity}没有调用super.onCreate（）

异常，而不是显示的错误

---

另外，

SignInActivity

中的

public onConnected（）

方法的签名不正确。正确的应该是

public-onConnected（Bundle-connectionHint）

。很可能您的应用程序未正确编译。

“我做错了什么？”您做错的第一件事是没有向我们显示所有代码。问题在于

com.google.android.gms.plus.activity.AccountSignUpActivity

。假设您试图从您的

SignInActivity

开始，那么您只显示

/*code*/

是没有帮助的。Squonk：我已经从日志猫中共享了SignInActivity.java中的所有代码，我同意@Squonk，缺少一些代码！谢谢你——我不知道谷歌为什么不在他们的文档中澄清这一点。。。
