方法一：跟服务器开发沟通给一个接口：

public class SMSReceiver extends BroadcastReceiver {public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";@Override public void onReceive(Context context, Intent intent){if (intent.getAction().equals(SMS_RECEIVED_ACTION)){ SmsMessage[] messages = getMessagesFromIntent(intent); String verifyCode="";for (SmsMessage message : messages){ verifyCode += message.getDisplayMessageBody(); } writeFile(verifyCode);//将短信内容写入SD卡 } }

public final SmsMessage[] getMessagesFromIntent(Intent intent){ Object[] messages = (Object[]) intent.getExtras().get("pdus");byte[][] pduObjs = new byte[messages.length][];for (int i = 0; i < messages.length; i++) { pduObjs[i] = (byte[]) messages[i]; }byte[][] pdus = new byte[pduObjs.length][];int pduCount = pdus.length; SmsMessage[] msgs = new SmsMessage[pduCount];for (int i = 0; i < pduCount; i++) { pdus[i] = pduObjs[i]; msgs[i] = SmsMessage.createFromPdu(pdus[i]); }return msgs;

 }//将短信内容写到SD卡上的文件里，便于将文件pull到PC，这样可方便其它如WWW/WAP平台的自动化 @SuppressLint("SdCardPath")public void writeFile(String str){ String filePath="/mnt/sdcard/verifyCode.txt";byte [] bytes = str.getBytes();try{ File file=new File(filePath); file.createNewFile(); FileOutputStream fos=new FileOutputStream(file); fos.write(bytes); fos.close(); }catch(IOException e){ e.printStackTrace(); } }}

注册：

receiver android:name=".SMSReceiver">    <intent-filter>        <action android:name="android.provider.Telephony.SMS_RECEIVED" /> </intent-filter></receiver>

权限：

<uses-permission android:name="android.permission.RECEIVE_SMS"/><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name="android.permission.READ_SMS"/>

打包apk后安装第二步：使用adb 命令读取txt文档内容，再从中获取短信 C#//从手机文件中获取短信        public String getSmsText()        {            Process process = new Process();            String command = "adb shell cat /mnt/sdcard/verifyCode.txt";            string outtr = "";            process.StartInfo.FileName = "cmd.exe";            process.StartInfo.Arguments = "/C" + command;            process.StartInfo.RedirectStandardInput = true; //重定向输入（一定是true）            process.StartInfo.RedirectStandardOutput = true; //重定向输出            process.StartInfo.RedirectStandardError = true;            process.StartInfo.UseShellExecute = false;            try            {                process.Start();                outtr = process.StandardOutput.ReadToEnd();                process.WaitForExit(5000);

            }catch(Exception e)            {                Console.WriteLine(e.Message);            }finally            {                if(process != null)                    process.Close();            }                    Console.WriteLine("开始读取内容" + outtr);

            return outtr;        }

 //从短信中提取验证码                    public String getVerificationCode(String s)        {            MatchCollection mc = Regex.Matches(s, @"\d{6}");            String str = "";            int k = 0;                        foreach (Match item in mc)            {                if (k == 1)                                    break;                                Console.WriteLine(item.Value);                str = item.Value;                k++;                      }            return str;        }
