先分享一下修改后的图片 

1.增加状态栏网络图标(有连接时才显示)，去除信号图标 
2. 增加设置“以太网设置”选项 
3. 增加“从不待机”选项，对应的实际值是-1 

 

 

  

 


友善之臂有提供了1个软件用于设置开发板的有线网络。如果你因某些原因不想使用或不方便使用这个软件，本文讲述如何移植让系统框架支持以太网的设置(DHCP动态分配IP或手动静态设置IP) 

主要是利用android-x86现成的Ethernet框架，添加到Tiny6410的android源码中，增加系统对Ethernet的支持。 
本文所用的是友善Tiny6410 2011-11-16版本的Android源代码。所有的修改都是基于此版本进行的。 
如果你懒得修改，可以直接用附件中改好的代码直接覆盖，当然前提是你使用的开发板型号、源代码版本一样才行。附件的内容仅供参考，除了增加Ethernet框架之外，还更改了一些默认设置。 
========================================================================================== 
先把友善android源代码解压放好 
一、准备工具：curl和repo 
yum install curl 
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo >
/bin/repo 
chmod a+x /bin/repo 

二、创建文件夹 
mkdir /opt/FriendlyARM/mini6410/ android /android-x86 
cd /opt/FriendlyARM/mini6410/ android /android-x86 

三、全部源码太大，只下载相关部分源码，gingerbread-x86代表2.3版本的源码 
repo init -u git://android-x86.git.sf.net/gitroot/android-x86/x86/platform/manifest.git -b gingerbread-x86 
repo sync platform/frameworks/base 
repo sync platform/packages/apps/Settings 

四、移植framework部分(+号的行代表增加的内容，-号的行代表删除的内容)
