启动服务，在接收短信的地方，获取到Intent对象，调用Context对象的startService()方法
获取到SP中保存的位置信息
发送短信，SmsManager.getDefault().sendTextMessage()方法，发送短信给安全号码，参数：sendTextMessage(目标手机, null(来源手机不支持), text, sentIntent, deliveryIntent)后两个参数，延迟报告和送达报告，不关心填null
需要这个权限 android.permission.SEND_SMS
判断一下内容是否为空，如果为空发送短信内容是正在获取，手动让坐标变化一下，才能正在得到
