Unity发布Android时需要的Android SDK/NDK的下载

一、Android SDK下载
官网(需FQ)：http://developer.android.com/sdk/index.html
Android Dev Tools官网地址 (无需FQ)：http://www.androiddevtools.cn/

以Android Dev Tools官网下载为例

1下载Android SDK Tools
进入 http://www.androiddevtools.cn/， 先找到SDK Tools,下载最新的版本即可。选择zip的，解压缩至目标路径位置即可

2 启动SDK Manager，勾选下载项，执行下载
(1) 双击SDK Manager

 

 

(2) Tools的勾选Android SDK Tools、Android SDK Platform-tools和Android SDK Build-tools

(3) API的任意选择一个，考虑向下兼容原则，可以下载最新的API。

(4) Extras的全选

(5) 点击Install xx packages… 按钮，然后点Accept License，最后点Install按钮

 

 

3 如果无法下载 (若下载正常，则跳过此步)

如果无法下载，此时可采用有Android SDK在线更新镜像的服务器来下载安装。
1 北京化工大学镜像服务器地址:
IPv4: ubuntu.buct.edu.cn/，端口：80
IPv4: ubuntu.buct.cn/，端口：80
IPv6: ubuntu.buct6.edu.cn/，端口：80
2 大连东软信息学院镜像服务器地址: mirrors.neusoft.edu.cn，端口：80
3 郑州大学开源镜像站: mirrors.zzu.edu.cn，端口：80

使用方法：
1 启动 Android SDK Manager，打开主界面，依次选择Tools、Options...，弹出Android SDK Manager - Settings窗口
2 在HTTP Proxy Server和HTTP Proxy Port输入框内填入上面镜像服务器地址(不包含http://，如下图) 和端口
3 选中Force https://... sources to be fetched using http://... 复选框
4 单击Close按钮关闭
5 依次选择Packages、Reload。

二、设置环境变量
(1) 新建一个系统环境变量，变量名为ANDROID_SDK_HOME，变量值为你的SDK安装路径

(2) 把%ANDROID_SDK_HOME%\platform-tools;%ANDROID_SDK_HOME%\tools添加到Path环境变量中。
(3) 检测是否配置成功。打开命令行窗口，输入adb。出现如下图所示内容则配置成功

三、在Unity中配置Android SDK安装路径
菜单: Edit - Preferences - External Tools, 选择Android SDK路径

四、NDK下载
