Ubuntu 14.04 设置Android开发环境

准备Java环境

本文只安装sdk，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

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

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

我创建了一个模拟设备。  最后运行该模拟设备。

创建工程

创建工程

--path MyFirstApp --activity MainActivity --package com.example.myfirstapp
> Created project directory: MyFirstApp

编译

运行下面的命令编译

ant debug
           

如果报以下错误：

[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
           

安装库：

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
           

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>
           

定义应用程序名称

如果想要修改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，比如：

<?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>
