篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了从零到完成安卓项目实战安卓端+后端相关的知识，希望对你有一定的参考价值。
今天下雨了，出不去了，在家开发一个安卓系统。
因为平时自己喜欢打篮球，那就开发一个篮球相关的系统吧：NBA安卓系统。
一，功能介绍
APP主要具备网上篮球约球、篮球交流、线上NBA观赛，力求软件界面友好、功能齐全、可拓展性良好。
系统的功能有：交流评论区模块、场馆预约模块、网上约球模块、约球留言模块、线上观赛模块、NBA球员分析模块。
通过线上篮球约球、球友交流评论、NBA比赛观看等功能，打造一款“线上观赛+线下实战”的篮球交友APP，帮助一些喜欢篮球运动的青少年可以随时随地观赛、组队、交流、交友。
二，开发语言介绍
APP基于JAVA语言进行开发，后台数据的存储采用 mysql 结合 Reids 实现数据存储，移动端通过 androidStudio 开发。
三，系统的界面介绍
四，核心代码演示
