| 18 | + * 要想使用BaseApplication，必须在组件中实现自己的Application，并且继承BaseApplication； |
| 19 | + * 组件中实现的Application必须在AndroidManifest.xml中注册，否则无法使用； |
| 20 | + * 组件的Application需置于java/debug文件夹中，不得放于主代码； |
| 21 | + * 组件中获取Context的方法必须为:Utils.getContext()，不允许其他写法； |
| 22 | + * BaseApplication主要有如下功能： |
| 23 | + * 1、全局获取Context； |
| 24 | + * 2、用来管理全局Activity； |
