==> Caveats
We will install android-sdk-tools, platform-tools, and build-tools for you.
You can control android sdk packages via the sdkmanager command.
You may want to add to your profile:
  'export ANDROID_SDK_ROOT=/usr/local/share/android-sdk'

This operation may take up to 10 minutes depending on your internet connection.
Please, be patient.

推荐答案

今天早上我遇到了类似的问题（尝试使用Unity3D为Android构建）。我最终卸载了JDK9并安装了 Java SE Development Kit 8u144 。希望这会有所帮助。

I had a similar problem this morning (trying to build for Android using Unity3D). I ended up uninstalling JDK9 and installing Java SE Development Kit 8u144. Hope this helps.

1. brew cask uninstall java ＃uninstall java9


2. brew tap caskroom / versions


3. brew cask install java8 #install java8


4. touch~ / .android / repositories.cfg ＃不带此文件，下一步会出错


5. brew cask install android-sdk

1. brew cask uninstall java # uninstall java9
2. brew tap caskroom/versions
3. brew cask install java8 # install java8
4. touch ~/.android/repositories.cfg # without this file, error will occur on next step
5. brew cask install android-sdk
