[APP] Android 开发笔记 001-环境搭建与命令行创建项目
1. 安装JDK，SDK
JDK http://www.oracle.com/technetwork/java/javase/downloads/index.html
Android SDK http://developer.android.com/sdk/index.html
https://dl.google.com/android/android-sdk_r24.4.1-windows.zip （No installer）
https://dl.google.com/android/installer_r24.4.1-windows.exe
Ant tool http://ant.apache.org/bindownload.cgi
Android SDK在线更新镜像服务器
|
2. 设置环境变量：
将下面两个加入系统环境变量表 Path键值中：
\Android\sdk\platform-tools
\Android\sdk\tools
设置Ant
ANT_HOME :指的是apache-ant-1.8.4-bin.zip的解压文件（apache-ant-1.8.4）所在的位置；
我把这个文件放在D盘，所以我这里设置的ant_home就是 ant_home=D:\apache-ant-1.8.2；
path路径设置为：PATH = %ANT_HOME%/bin; %ANT_HOME%/lib即可
3. 使用命令行创建Android应用：
1) 进入需要创建Android应用的文件夹：
cd D:\Android Development
2）在当前路径下，创建Android 项目
android create project -n MySecApp -p android_Sec -a MyActivitySec -k Com.test.mysecapp -t 2
命令行说明：
-n 表示 name 跟项目名称
-p 表示 path 跟工作空间
-a 表示 创建的Activity的名称
-k 表示 package 跟包名称
-t 表示 target 跟target id
(*target id * 可以通过 android list targets 查看,系统将列出所有的下载好的可用的 android 版本号)
3）使用命令给APK打包
