原生项目集成最新版本ReactNative，手把手教你如何一步步集成到原生项目中

仿微信聊天界面简洁易懂， 代码量超级小，就三四个类放心下载

X5内核与原生内核对比

仿手机通讯录 demo 这个demo 绝对值

简单实用的，让分享变得不再复杂，几行代码搞定。

下载后可直接运行，扫描识别支持二维码/条形码 并且支持生成二维码，内有联系Q 欢迎进行技术交流

Viewpager支持点击动态增加页面 可以直接获取页面数 Java编写界面 定义控件大小以及位置详细注解

支付宝跳转 demo 可以直接使用 以测试过

仿制 去年火爆游戏2048开发的同款 功能全部实现 大家可以放心下载

Android多线程断点续传下载器，很好的学习资料，包括完整代码以及详细注释。 无须其他配置，服务器端只需建立一个Dynamic project，然后包含一个mp3文件即可

Android 倒计时Demo 很简单实用 下载就可以运行

反编译神器 本人亲自尝试反编译出了支付宝 支持apk dex dex转txt dex转jar 等许多功能

Java参考文档

Android官方文档 最全最新中文版官方文档

屏幕取色器

简单实用 可以直接运行 不用做过多修改

ViewPager广告轮播+无限循环+定时播放 高仿搜狐轮播图 可直接使用

类似QQ分组 点击可以展开 listview 自定义内容

类似于QQ 微信等聊天或者下载App 状态栏提醒 可点击进入
