Android开源框架之XUtils

• 简介
  xUtils3 是 xUtils 的升级版，功能和性能都在提高，xUtils3 主要有四大模块：注解模块，联 网模块，图片加载模块，数据库模块；

  注解模块： 用于在 Activity 或者 Fragment 中初始化布局文件，便于代码更加简洁；
  联网模块： xUtils3 支持超大文件(超过2G)上传，更全面的http请求协议支持(11种谓词)， 拥有更加灵活的 ORM，更多的事件注解支持且不受混淆影响；
  图片加载模块： 加载图片很方便并且不用担心内存溢出，还可以图片绑定支持 gif(受系统兼容 性影响, 部分 gif 文件只能静态显示), webp; 支持圆角, 圆形, 方形等裁剪, 支持自动旋转.
  数据库模块： 数据库 api 简化提高性能, 达到和 greenDao 一致的性能
