//这里判断方法各个平台都有差异，我主要介绍下MTK平台的

//sim卡插入时，会产生ecclist(即默认的紧急号码)的系统属性值，一般mtk平台，在ril_sim.c中进行修改

//Read from SIM1

//Read from SIM2

for(String emergencyNum : numbers.split(",")){

if((emergencyNum.equals(number) || (emergencyNum + "+").equals(number){

}

//Read from SIM4

//从紧急列表中判断

String　emergencyNumberList = {"112","911","000","08","110","118","120","119","122"};
