前面我们把需要拦截的手机号都存储和展示出来了，接下来是使用广播接收者拦截短信了，这个广播接收者需要和一个服务绑定，服务开启的时候，接收者存在，服务停掉时，接收者关闭
在service包下定义一个类CallSmsSafeService继承系统的Service
重写onCreate()方法
获取BroadcastReceiver对象，new出来
调用registerReceiver()方法，注册广播，参数：BroadcastReceiver对象，IntentFillter对象
重写onDestory()方法
调用unregisterReceiver()方法，参数：BroadcastReceiver对象
BroadcastReceiver对象置为null
定义一个内部类InnerSmsReceiver继承系统的BroadcastReceiver
重写 onReceive()方法，传递进来参数：Context对象，Intent对象
调用Intent对象的getExtras().get(“pdus”)方法，获取到Object[]数组
for循环Object[]数组，每个是Object对象
调用SmsMessage.createFromPdu()方法，获取到SmsMessage对象，参数：byte[]数组，强转Object对象
调用SmsMessage对象的getOriginatingAddress()方法，得到String发件人
调用Dao对象的查询数据库方法，查出这条短信的拦截模式
判断拦截模式，如果是全部拦截3或者短信拦截2，就调用abortBroadcast()方法
在设置中心对上面的服务进行配置，达到开启和关闭的功能
