android 13 以太网

一、引言


        首先需要实现android13设置静态IP的功能，就要对android13以太网架构变化大致理解，谷歌把以太网相关的功能进行模块化，提取到packages/modules/Connectivity/目录，导致之前的实现需要调整，本文主要从2大块进行阐述，分别为framework与原生Settings。

        本文涉及功能点主要有如下几点：

        1.设置IP的方式分为DHCP和静态两种

        2.IP地址的设置

        3.子网掩码设置

        4.DNS设置

        5.网关设置

        6.代理设置

二、Framework部分

        2.1、涉及修改的类

  1. packages/modules/Connectivity/framework-t/api/module-lib-current.txt
  2. packages/modules/Connectivity/framework-t/src/android/net/EthernetManager.java
  3. packages/modules/Connectivity/framework-t/src/android/net/IEthernetManager.aidl
  4. packages/modules/Connectivity/framework/api/current.txt
  5. packages/modules/Connectivity/framework/api/system-current.txt
  6. packages/modules/Connectivity/framework/src/android/net/IpConfiguration.java
  7. packages/modules/Connectivity/framework/src/android/net/ProxyInfo.java
  8. packages/modules/Connectivity/service-t/src/com/android/server/ethernet/EthernetNetworkFactory.java
  9. packages/modules/Connectivity/service-t/src/com/android/server/ethernet/EthernetServiceImpl.java
  10. packages/modules/Connectivity/service-t/src/com/android/server/ethernet/EthernetTracker.java

        2.2、涉及类修改阐述

                android其实不管怎么更新，都离不开client-aidl-server这样的模式，所以大体思路就是根

                据以太网源码框架，在其上模仿原有的接口进行添加内容的方式，先把路打通。

                2.2.1、客户端接口添加及修改

1.IEthernetManager.aidl类中添加4个接口，提供给上层使用

四、总结

        至此关于android13以太网的功能介绍完毕，实际上博主认为技术分享应该是无私的，而并非作为牟利的工具，看到很多技术收费的文章，这其实对于自我的成长进步有很大的限制，微薄的利益回报并不值得，博主后续会继续更新对开发有益的文章，愿人人成为大神。
