重装 Android Studio之后发现出现以下错误，导致不能正常make Android工程。

Fail 原因如下：

• Failed to install the following Android SDK packages as some licences have not been accepted.

• build-tools;28.0.3 Android SDK Build-Tools 28.0.3

• platforms;android-28 Android SDK Platform 28

• To build this project, accept the SDK license agreements and install the missing components using the Android Studio SDK Manager.

• Alternatively, to transfer the license agreements from one workstation to another, see http://d.android.com/r/studio-ui/export-licenses.html

• Using Android SDK: D:\software\sdk

主要原因是电脑上之前已经安装过SDK,没有接受 许可协议导致的。

首先打开命令行，进入到报错的sdk路径，找到可以处理licences的文件

• D:\software\test>cd ..

• D:\software>cd sdk
• D:\software\sdk>cd tools
• D:\software\sdk\tools>cd bin
• D:\software\sdk\tools\bin>sdkmanager --licenses

• Warning: File C:\Users\Administrator\.android\repositories.cfg could not be loaded.

• 6 of 6 SDK package licenses not accepted.

• Review licenses that have not been accepted (y/N)? y

• ..... 巴拉巴拉一大堆协议，请输入y 否则不管用Android Studio

接受完协议之后就可以正常运行Android Studio了。
