Here is step by step description for how to read incoming sms in android

您需要为此使用广播接收器

You need to use broadcast receiver for that

1. 在AndroidManifest中声明接收器

1. Declare receiver in AndroidManifest

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

在AndroidManifest中授予读取短信权限

Give read SMS permission in AndroidManifest

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

IncomingSms.java文件详细信息: 我已在此文件中接收了广播事件 1.创建带有扩展的BroadcastReceiver类的类IncomingSms

IncomingSms.java file details : I have made broadcast event reciever in this file 1. Created class IncomingSms with extends BroadcastReceiver class

public class IncomingSms extends BroadcastReceiver


  2. Get the object of SmsManager to find out received sms details

//获取SmsManager的对象

// Get the object of SmsManager

final SmsManager sms = SmsManager.getDefault();


  3.  Create method receiver()


public void onReceive(Context context, Intent intent)


    4. Get / Read current Incomming SMS data

//从意图中检索扩展数据的映射.

// Retrieves a map of extended data from the intent.

final Bundle bundle = intent.getExtras();

try {

    if (bundle != null) {

        final Object[] pdusObj = (Object[]) bundle.get("pdus");

        for (int i = 0; i < pdusObj.length; i++) {

            SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
            String phoneNumber = currentMessage.getDisplayOriginatingAddress();

            String senderNum = phoneNumber;
            String message = currentMessage.getDisplayMessageBody();

            Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message);


           // Show alert
            int duration = Toast.LENGTH_LONG;
            Toast toast = Toast.makeText(context, "senderNum: "+ senderNum + ", message: " + message, duration);
            toast.show();

        } // end for loop
      } // bundle is null

} catch (Exception e) {
    Log.e("SmsReceiver", "Exception smsReceiver" +e);
