1：KeyDispatchTimeout(5 seconds) --主要类型
按键或触摸事件在特定时间内无响应
2：BroadcastTimeout(10 seconds)
BroadcastReceiver在特定时间内无法处理完成
3：ServiceTimeout(20 seconds) --小概率类型
Service在特定的时间内无法处理完成

出现ANR问题的原因就是上面红色代码中
at com.rayray.cool.activity.WoDeJianYiActivity$1.onClick(WoDeJianYiActivity.java:173) 是Android中Activity
at com.rayray.cool.util.URLUtil.invokeURL(URLUtil.java:136) 是一次耗时的联网请求
Activity中的按键事件在特定事件内未响应造成。
（1）耗时的操作放入单独的线程中处理，如（联网、数据库、IO）
（2）尽量避免和UI线程的操作
