自我介绍一下，小编13年上海交大毕业，曾经在小公司待过，也去过华为、OPPO等大厂，18年进入阿里一直到现在。

深知大多数初中级安卓工程师，想要提升技能，往往是自己摸索成长，但自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！

因此收集整理了一份《2024年最新Android移动开发全套学习资料》送给大家，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友，同时减轻大家的负担。

由于文件比较大，这里只是将部分目录截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频 如果你觉得这些内容对你有帮助，可以添加下面V无偿领取！（备注Android）

最后

赠送大家一套完整的Android学习资料吧。

以前一直是自己在网上东平西凑的找，找到的东西也是零零散散，很多时候都是看着看着就没了，时间浪费了，问题却还没得到解决，很让人抓狂。

后面我就自己整理了一套资料，还别说，真香！

资料有条理，有系统，还很全面，我不方便直接放出来，大家可以先看看有没有用得到的地方吧。
