Google Plus登录Android?

标签: android google-plus

以下是我使用Google Plus登录的代码。发生一些内部错误。我想知道我在代码中做错了什么。

当我使用SCOPE:SCOPE_PLUS_PROFILE时,登录成功,但我无法获取用户的个人详细信息。我想通过使用Google plus集成获取用户详细信息来登录。如果有人使用谷歌的工作代码登录,那么请帮帮我吗?

我尝试过来自this link的方法。此外,我已在Google开发者控制台上注册了此项目。

很抱歉,如果它没有帮助,但我想我可能有一个解决方案,可以帮助您找到正确的解决方法。

我刚刚解决了我自己的问题,我有以下清单:

  • 确保您使用的是debug.keystore SHA-hash或您希望使用的任何密钥库
  • 确保清单和类文件中的软件包名称与开发人员控制台中的软件包名称完全相同。
  • 检查Google开发者控制台是否有正确的API供您使用
  • 在开发人员控制台中的同意屏幕部分填写基本必需数据
  • 如果您的代码中存在逻辑问题,请查看官方建议的实现是如何从教程网站进行的,或者进一步查看github链接(here
  • 尝试在eclipse / IDE和&amp ;;重新编译和重新制作项目。开发者控制台

有关内部错误的简要说明表明您的Google登录API实施不正确,有更多信息(here)。我自己的问题是基于我在解码代码中的连接时使用的逻辑。我首先重新构建了我的项目,然后更改了实现,并在使用API​​时发现了一些小错误并纠正了它们以使其运行。 希望这对你也有帮助。

改变这个:

.addOnConnectionFailedListener(this).addApi(Plus.API, null)

到此:

.addOnConnectionFailedListener(this).addApi(Plus.API)

为我工作。
