我在这里做 google + integartion。我正在使用以下代码，但我面临的错误是:onConnectionFailed: ConnectionResult.getErrorCode() = 4。所以请任何人帮助我并告诉我我做错了什么这段代码并为我提供解决方案。我将非常感谢你。我搜索了很多但一无所获。我正在使用 Google plus 的快速示例。还有另一个问题，我无法获取生日等个人信息这段代码中的等等。

我遇到了同样的问题。我在 google api 控制台 >> 同意屏幕中解决了问题，并添加了产品名称。

我试试这个教程:http://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/

在主要 Activity 中，您需要将 .addApi(Plus.API, null) 更改为 .addApi(Plus.API, Plus.PlusOptions.builder().build())

关于android - onConnectionFailed : ConnectionResult. getErrorCode() = 4，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24263974/
