深知大多数Android工程师，想要提升技能，往往是自己摸索成长或者是报班学习，但对于培训机构动则几千的学费，着实压力不小。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Android移动开发全套学习资料》，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。

既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，基本涵盖了95%以上Android开发知识点，真正体系化！

由于文件比较大，这里只是将部分目录大纲截图出来，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，并且后续会持续更新

最后

由于文章篇幅原因，我只把面试题列了出来，详细的答案，我整理成了一份PDF文档，这份文档还包括了还有 高级架构技术进阶脑图、Android开发面试专题资料，高级进阶架构资料，帮助大家学习提升进阶，也节省大家在网上搜索资料的时间来学习。
