在Mac上查找Android SDK并将其添加到PATH [英] Finding Android SDK on Mac and adding to PATH

问题描述

我已经在MacBook Air(操作系统版本10.11 El Capitan)上安装了Android Studio，并成功编写了一个小型的"hello，world"应用程序，并安装在设备(Nexus 7)上，并在AVD上运行.我现在要做的就是能够从命令行(而不是Android Studio)构建该应用程序并将其安装在设备上.我正在按照这里的指示进行操作:

I have installed Android Studio on my MacBook Air (OS Version 10.11 El Capitan) and have successfully written a small "hello, world" app and installed on device (Nexus 7) and ran on AVD. All I want to do now is be able to build the app and install it on device from the command line as opposed to Android Studio. I'm following the directions here:

，相关行是:

确保PATH环境变量中包含Android SDK platform-tools/目录，然后执行:

Make sure the Android SDK platform-tools/ directory is included in your PATH environment variable, then execute:

问题是我在机器上找不到Android SDK！我认为它在那里是因为否则程序将无法编译并通过Android Studio运行?也许这是一个错误的假设?我是Mac的新手(我曾经使用过Windows)，所以我不知道搜索Android SDK的最佳方法.所以我的问题:

The problem is I can't find the Android SDK on my machine! I assume it's there because otherwise the program wouldn't compile and run through Android Studio? Perhaps that's a bad assumption? I'm new to Macs (I'm used to Windows) so I don't know the best way to search for the Android SDK. So my questions:

1. 如何在计算机上找到Android SDK?还是向自己证明它不存在?
2. 如果没有，我该如何安装?
3. 如何更改PATH以包括Android SDK?

推荐答案

1.怎么找到

• 打开Android Studio，转到 Android Studio>偏好设置"
• 搜索sdk
• 与此类似的东西(如您所见，这是一个Windows框)将显示

1. How to find it

• Open Android studio, go to Android Studio > Preferences
• Search for sdk
• Something similar to this (this is a Windows box as you can see) will show

大多数情况下，您可以看到那里的位置

You can see the location there – most of the time it is:

/Users/<name>/Library/Android/sdk

2.如果没有的话，如何安装

• 转到 Android独立SDK下载页面
• 下载macOS的zip文件
• 将其提取到目录

2. How to install it, if not there

• Go to Android standalone SDK download page
• Download the zip file for macOS
• Extract it to a directory

打开您的终端，通过键入以下内容来在nano中编辑您的~/.bash_profile文件:

Open your Terminal edit your ~/.bash_profile file in nano by typing:

nano ~/.bash_profile

如果您使用Zsh，请改为编辑~/.zshrc.

If you use Zsh, edit ~/.zshrc instead.

转到文件末尾，然后将目录路径添加到您的$PATH:

Go to the end of the file and add the directory path to your $PATH:

export PATH="${HOME}/Library/Android/sdk/tools:${HOME}/Library/Android/sdk/platform-tools:${PATH}"

• 按Ctrl+X
保存
• 重启终端
• 要查看其是否正常运行，请输入添加目录(例如adb)内的任何文件或二进制文件的名称，并验证其是否已打开/执行
• Save it by pressing Ctrl+X
• Restart the Terminal
• To see if it is working or not, type in the name of any file or binary which are inside the directories that you've added (e.g. adb) and verify it is opened/executed
