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

packages/modules/Connectivity/service-t/src/com/android/server/ethernet/EthernetServiceImpl.java
packages/modules/Connectivity/service-t/src/com/android/server/ethernet/EthernetTracker.java2.2、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。文章来源地址https://www.toymoban.com/news/detail-766041.html
到了这里，关于Android13 原生以太网实现设置静态IP的文章就介绍完了。如果您还想了解更多内容，请在右上角搜索TOY模板网以前的文章或继续浏览下面的相关文章，希望大家以后多多支持TOY模板网！
