Ubuntu 14.04 设置Android开发环境
准备Java环境
本文只在Ubuntu 14.04下安装ndk，不安装什么IDE，因为我只需要命令行模式开发即可。
首先安装openjdk 1.6，然后安装ant，这个不赘述。
下载SDK
从这里下载SDK for Linux 64bit的版本: http://developer.Android.com/sdk/index.html?hl=sk#download
下载后，解压到本地目录，比如/opt/目录下， 然后设置环境变量，添加三行到~/.bashrc文件
export ANDROID_HOME=/opt/android-sdk-linux
PATH=$PATH:/opt/android-sdk-linux/tools
PATH=$PATH:/opt/android-sdk-linux/platform-tools
运行Android SDK Manager
运行android命令，将会弹出SDK Manager对话框，从中选择需要的package进行安装
安装模拟设备
android avd
具体参考官方文档：http://developer.android.com/training/basics/firstapp/running-app.html
我为自己的moto680创建了一个模拟设备。 最后运行该模拟设备。

编译
运行下面的命令编译
ant debug
部署程序到模拟器
$ adb install bin/MyFirstApp-debug.apk
97 KB/s (4858 bytes in 0.048s)
pkg: /data/local/tmp/MyFirstApp-debug.apk
Success
运行程序
好了，现在可以在模拟器里面运行程序了。 运行程序MainActivity，显示下面的文字:
Hello World, MainActivity
该文字其实是定义在./res/layout/main.xml 文件中:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World, MainActivity"
/>
</LinearLayout>
