获取错误“；Google Play服务不可用。此应用程序将关闭"；在Android设备上安装Android版本4.1.2

我是Android编程世界的新手。 我正在尝试使用上的文档创建一个G+登录。 （我是用安卓工作室做的）

我成功地登录和注销了我的Moto-G（Android版本5.0.2）。然而，我不能对三星Galaxy Trend（Android版本4.1.2）做同样的事情。我在这里遇到的错误是：“Google Play服务不可用。此应用程序将关闭。”

除了文档中提到的以外，我没有做任何事情。 有人能告诉我这里出了什么问题吗

谢谢

当我的android没有更新时，我就遇到了这种情况。这是我2年前使用的检查代码
