mac下android的环境变量配置

Where the Android-SDK is installed depends on how you installed it.

1.通过官网直接下载安装

If you downloaded the SDK through their website and then dragged/dropped the Application to your Applications folder, it’s most likely here:

1

/Applications/ADT/sdk (as it is in your case).

2.通过Homebrew安装

If you installed the SDK using Homebrew (brew cask install android-sdk), then it’s located here:

1

/usr/local/Caskroom/android-sdk/{YOUR_SDK_VERSION_NUMBER}

3.通过Android Studio安装

If the SDK was installed automatically as part of Android Studio then it’s located here:

1

/Users/{YOUR_USER_NAME}/Library/Android/sdk

知道sdk目录后

1

vim ~/.bash_profile

按向下箭头->按i进入编辑模式

export ANDROID_HOME={YOUR_PATH}

export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

export PATH=$PATH:<PATH 1>:<PATH 2>:<PATH 3>:------:<PATH N>

最后：ESC后 :wq 保存并退出。
更新变化：
