使用 FusedLocationProviderApi 的 Android 定位

Question

我正在尝试使用 FusedLocationProviderApi 在我的平板电脑上获取位置数据，但每当我启动该应用程序时，我都会收到错误

E/MainActivity:连接失败:ConnectionResult{statusCode=SERVICE_VERSION_UPDATE_REQUIRED, resolution=null}

我不知道是什么导致了这个错误。我有一种非品牌平板电脑，我认为这可能是导致问题的原因。型号:DL701Q，Android 版本:4.4.2 和 google play 构建版本 4.9.13

这是我的应用程序代码，在我测试以找出问题时，有些东西被注释掉了。

您应该将平板电脑上的 GooglePlay Services 服务“应用程序”升级到更高版本，例如 7.5.74，以便与客户端库版本 7.5.0 进行交互另见 this有关如何升级它的进一步说明
