How to read text messages from Android

public class SMSReceiver extends BroadCastReceiver {

    // The method that is performed when a specified action occurs 
    @Override
    public void onReceive(Context context, Intent intent) {

        // Insert if statement to respond only when SMS is received
        if (intent.getAction().equals(
            "android.provider.Telephony.SMS_RECEIVED")) {
            StringBuilder sms = new StringBuilder(); // Where to store SMS characters
            Bundle bundle = int.getExtras(); // Receives text to Bundle object

            if (bundle != null) {
                // Receives character data contained in the bundle as an object array
                Object[] pdusObj = bundle.get("pdus");

                // Create an array of sms messages to receive SMS
                SmsMessage[] messages = new SmsMessage[pdusObj.length];
                for (int i = 0; i < pdusObj.length; i++) {
                    messages[i] =
                        SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    // CreateFromPdu, the static method of SmithMessage, is pdusObj's
                    // Put the data in the message
                    // At this time, pdusObj needs to be transformed into a byte array
                }

                // Save data in SmsMessage array to sms as append method
                for (SmsMessage smsMessage : messages) {
                    // The getMessageBody method is a method for receiving text bodies
                    sms.append(smsMessage.getMessageBody());
                }

                sms.toString() // Convert StringBuilder object sms to String
            }
