推荐答案

您必须通过独立SDK管理器更新Google Play服务和Google存储库.

You have to update your Google Play Services and Google Repository from the Standalone SDK Manager.

编辑:从最新版本的Android Studio起，独立SDK管理器已删除.您必须转到"SDK工具"标签.

As of the latest version of Android Studio the Standalone SDK Manager is removed. You must go to the SDK Tools tab.

首先，打开Android Studio，然后单击顶部工具栏上的此图标:

First off, open Android Studio and click this icon at the top toolbar:

然后，在对话框启动时，单击对话框左下方的启动独立SDK管理器":

Then, when the dialog launches, click "Launch Standalone SDK Manager" at the bottom left of the dialog:

要确保没有其他任何东西需要更新/安装，请单击取消全选":

To make sure nothing other than what we want gets updated/installed, click "Deselect All":

当独立SDK管理器"窗口打开时，查找其他"并将其折叠.您应该看到"Google Play服务"和"Google存储库"，在右侧应该看到可用更新:{something}" .选择这些项目，然后单击安装".

When the Standalone SDK Manager window opens, look for "Extras" and collapse it. You should see "Google Play Services" and "Google Repository" and on the right you should see "Update Available: {something}". Select these to items and click "Install".

完成安装后，错误将消失.

When they're done installing, the error will go away.
