后台发送短信

注册权限

<uses-permission android:name="android.permission.SEND_SMS" />

代码实现 :

// 获取信息内容

String message ;

// 移动运营商允许每次发送的字节数据有限，我们可以使用Android给我们提供 的短信工具。

if (message != null) {

SmsManager sms = SmsManager.getDefault();

// 如果短信没有超过限制长度，则返回一个长度的List。

List<String> texts = sms.divideMessage(message);

for (String text : texts) {

sms.sendTextMessage(“这里是接收者电话号码”, “这里是发送者电话号码”, “这里是短信内容”, null, null);

}

}

//说明

sms.sendTextMessage(destinationAddress, scAddress, text, sentIntent, deliveryIntent)：

destinationAddress:接收方的手机号码

scAddress:发送方的手机号码

text:信息内容

sentIntent:发送是否成功的回执，

DeliveryIntent:接收是否成功的回执，

从google搜索内容
