6、om();r.setSeed(System.currentTimeMillis();int verifyTemp=0;String verifyCode=""for(int i=0;i<4;i+)verifyTemp=r.nextInt(10);verifyCode += verifyTemp;content="Dear "+countryName+" friend, " +"your verified code is"+verifyCode+"nSent By BigApp"/發(fā)送短信S

7、msManager smsManager=SmsManager.getDefault();/分割短信/if(content.length()>70)/List<String> msgs=smsManager.divideMessage(content);/Iterator<String> iter=msgs.iterator();/while(iter.hasNext()/String msg=iter.next();/將msg發(fā)送到接收方/smsManager.sendTextMessage(phone, null, content, null, null);c
