手机系统属性——SunWTK/lib下的system.config文件定义

写程序时都使用System.getProperty(String)来获得系统属性。自己找了一下，发现是在SunWTK安装目录下lib文件夹下的system.cofig文件进行的规范约束。

所有规范约束如下：

补充：真机上另有，返回存储卡信息

fileconn.dir.memorycard



获得短信服务中心号码

wireless.messaging.sms.smsc

如果手机支持

WMA

则可以通过获得属性“

wireless.messaging.sms.smsc

”的值，来获得短信服务中心号码。对于国内的三个运营商来说，中国移动的短信服务中心号码是

13800XXX500,

其中

XXX

为号码所属的地区电话区号，中国联通的短信服务中心号码比较乱，但是均以

130

开头，包括

3G

的手机，而对于中国电信的手机，咨询客服以后均告知不需要设置短信服务中心号码。
