Android Studio提示"licences have not been accepted"

Linux或Mac首次运行Android Studio，报了以下的错误：

ERROR: Failed to install the following Android SDK packages as some licences have not been accepted.
   platforms;android-25 Android SDK Platform 25
   build-tools;28.0.2 Android SDK Build-Tools 28.0.2
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
...

错误提示，我电脑没有接受Licence，widnows下不存在这种报错，由于在点击"下一步"的过程当中勾选了"I Agree"。Linux和Mac下面稍有不一样，须要切换到SDK的Tools文件夹下，执行：

$ cd /home/xiaotang/Android/Sdk/tools/bin
$ ./sdkmanager --licenses

而后，接着一直输入：Y Y ... 就能够了。

Warning: File /home/xiaotang/.android/repositories.cfg could not be loaded.

问题解决。
