Build Android Develope Enviroment

How to Start Android Developing

1. Prepare a Developing System

Install a 64bit/32bit Linux system.

One suggestion is the latest version of Ubuntu.

2. Install some developing tools

(1)Build essentials, execute following commands in terminal:

sudo apt-get install build-essential

(build-essential的作用 ：

linux操作系统上面开发程序， 光有了gcc 是不行的，它还需要一个 build-essential软件包，作用是提供编译程序必须软件包的列表信息，也就是说 编译程序有了这个软件包，它才知道 头文件在哪，才知道库函数在哪，还会下载依赖的软件包 ， 最后才组成一个开发环境，当然 build-essential包 安装时 需要的依赖包 有些你用不上

软件包: build-essential 安装方法：

sudo apt-get install build-essential )

sudo apt-get install automake

自动生成Makefile

sudo apt-get install subversion

一个免费开源的版本控制工具

3. Install Eclipse

Search Eclipse in Ubuntu Software Center and install.

/sdk/index.html 提供专门供Android使用的绑定的Eclipse和SDK

4. Install JRE and JDK

For JRE:

Install OpenJDK Java 7 from Ubuntu Software Center.

For JDK: Download the file to /Download folder from:

/technetwork/java/javase/downloads/index.html

Install:

cd ~/Downloads

sudo chmod +x jdk-6u37-linux-i586.bin

./jdk-6u37-linux-i586.bin

5. Install Android SDK

The Android SDK provides you the API libraries and developer tools.

(1) Download the SDK

Download the SDK from /sdk/index.html,

and extract to a folder such as:

/home/steveyang/Documents/android-sdk-linux

(2) Install the SDK

Open the SDK client with the following commands:

cd /home/steveyang/Documents/android-sdk-linux/tools

./android

Install the Android SDKs after Android2.3.3 with the client.

(3) Install Eclipse plugins

Follow the guide in:

/sdk/installing/installing-adt.html

Start Eclipse, then select Help > Install New Software.

 Click Add, in the top-right corner.

 In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the

following URL for the Location:

/android/eclipse/

6. Install NDK

The NDK allows you to implement parts of your app with native-code languages such as

C and C++.

Download the NDK_r8e for Linux from the below link:

/android/ndk/android-ndk-8e-linux-x86.tar.bz2

Extract the NDK_r8e package, to a path such as

/opt/androidbuild/android-ndk-r8e

sudo chmod -R 755 /opt/androidbuild/android-ndk-r8e

7. Config build settings

(1) Config system environment:

sudo ln -s /home/steveyang/Documents/android-sdk-linux /opt/android-sdk-linux_x86

Add environment variable::

gedit .bashrc

export NDK_HOME=/opt/androidbuild/android-ndk-r8e

export JAVA_HOME=/home/steveyang/Downloads/jdk1.6.0_37

export JRE_HOME=/home/steveyang/Downloads/jdk1.6.0_37/jre

export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH

export PATH=$NDK_HOME:$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

source .bashrc

命令用法：

source FileName

作用:在当前bash环境下读取并执行FileName中的命令。

注：该命令通常用命令“.”来替代。

如：source /etc/profile 与 . /etc/profile是等效的。

注意：source命令与shell scripts的区别是， source在当前bash环境下执行命令，而scripts是启动一个子shell来执行命令。这样如果把设置环境变量（或alias等等）的命令写进scripts中，就只会影响子shell,无法改变当前的BASH,所以通过文件（命令列）设置环境变量时，要用source 命令。

(2) Eclipse project:

a. Import project:

ui/MediaFramework/SampleApp/Android/mfw_samples

ui/MediaFramework/SDK/Android/build/MFWSdk

ui/MediaFramework/SampleApp/Android/ThemePhone

ui/MediaFramework/SampleApp/Android/ThemeTablet

ui/MediaFramework/SampleApp/Android/ FileExplorer
