思路：
?
?对来电进行监控
1）对于通讯录的电话来电不做监控
2）对于通讯录里没有的电话号码进行监控
监控规则：
? 1）正则匹配 如：杭州的本地号码需要接听 其他地区来电拒接
? 2）如果一些确认需要来电的号码但又不想加入黑名单的号码 加入白名单管理列表；
? 3）如果是手机来电，拒接的发送一条短信（询问是何人找我干什么事情？避免误伤），如果是座机就误伤吧！

??????????????? }
??????? }
}
在AndroidManifest.xml，配置写好的Receiver，并拦截相应的BroadCastAction，
另外注意加上相应的权限。
<receiver android:name=".filter.PhoneStatReceiver">?
??????????? <intent-filter>
???????????????? <action android:name="android.intent.action.PHONE_STATE"/>??????????
???????????????? <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
??????????? </intent-filter>
</receiver>
<uses-permission android:name="android.permission.READ_CONTACTS"/>?
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
??? ??? 来电分三种状态：
CALL_STATE_RINGING：来电响铃
CALL_STATE_OFFHOOK：摘机
CALL_STATE_IDLE：挂机
