准备Java环境

本文仅仅安装sdk，不安装什么IDE，由于我仅仅须要命令行模式开发就可以。

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的版本号: http://developer.android.com/sdk/index.html?hl=sk#download

wget http://dl.google.com/android/android-sdk_r23.0.2-linux.tgz

下载后，解压到本地文件夹，比方/opt/文件夹下， 然后环境变量设置，加入三行到~/.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

执行Android SDK Manager

执行android命令。将会弹出SDK Manager对话框，从中选择须要的package进行安装

安装模拟设备

android avd

我创建了一个模拟设备。  最后执行该模拟设备。

创建工程

创建工程

AndroidManifest.xml  ant.properties  bin  build.xml  libs  local.properties  proguard-project.txt  project.properties  res  src

编译

执行以下的命令编译

ant debug

假设报以下错误：

     [aapt] /opt/android-sdk-linux/build-tools/19.0.3/aapt: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

sudo apt-get install lib32z1

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

执行程序

Hello World, MainActivity

该文字事实上是定义在./res/layout/main.xml 文件里:

<?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>

定义应用程序名称

假设想要改动Android中的应用程序名，不是在pom.xml中编辑，而是在src/values/strings.xml中定义，比方：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">mvn_example1</string>
    <string name="edit_message">Enter a message</string>
    <string name="button_send">Send</string>
    <string name="action_settings">Settings</string>
    <string name="title_activity_main">MainActivity</string>
</resources>
