利用smsmanager实现后台发送短信示例

public void sendServiceSms(Context mContext,String content) {
try {
SmsManager manager = SmsManager.getDefault();
PendingIntent sentIntent = PendingIntent.getBroadcast(mContext, 0,
new Intent(SMS_SENT_TEST_ACTION), 0);
manager.sendTextMessage("13912345670", null, content, sentIntent, null);
} catch (Exception e) {
e.printStackTrace();
}
}
