i m trying to read OTP from message, but i cant auto read it.please tell me what i did wrong, here is my code.i m using marshmallow. thank you.
here is my SmsReceiver class:
public class SmsReceiver extends BroadcastReceiver {
private static SmsListener mListener;
@Override
public void onReceive(Context context, Intent intent) {
Bundle data = intent.getExtras();
Object[] pdus = (Object[]) data.get("pdus");
for(int i=0;i<pdus.length;i++){
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
String sender = smsMessage.getDisplayOriginatingAddress();
//You must check here if the sender is your provider and not another one with same text.
String messageBody = smsMessage.getMessageBody();
//Pass on the text to our listener.
mListener.messageReceived(messageBody);
}
}
public static void bindListener(SmsListener listener) {
mListener = listener;
}}
here is interface
public interface SmsListener {
public void messageReceived(String messageText);
}
and this is my activity
public class MyOTP extends BaseActivity implements View.OnClickListener {
EditText txtotp;
Button btnSubmitOtp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_otp);
txtotp = (EditText) findViewById(R.id.txtOtp);
btnSubmitOtp = (Button) findViewById(R.id.btnSubmit);
btnSubmitOtp.setOnClickListener(this);
SmsReceiver.bindListener(new SmsListener() {
@Override
public void messageReceived(String messageText) {
Log.d("Text",messageText);
Toast.makeText(MyOTP.this,"Message: "+messageText,Toast.LENGTH_LONG).show();
}
});
}
}

Here is my working Broadcast receiver class which will read digits from message body & broadcast with OTP code to related class
You need to add these permissions in menifest file
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission-sdk-23 android:name="android.permission.READ_SMS" />
<uses-permission-sdk-23 android:name="android.permission.RECEIVE_SMS" />
Here is my receiver class
public class SmsListener extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
Bundle bundle = intent.getExtras(); //---get the SMS message passed in---
SmsMessage[] msgs = null;
String msg_from;
if (bundle != null) {
//---retrieve the SMS message received---
try {
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i = 0; i < msgs.length; i++) {
if (Build.VERSION.SDK_INT <= 22) {
msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
} else {
msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i], bundle.getString("format"));
}
msg_from = msgs[i].getOriginatingAddress();
if (msg_from.contains("PINSMS")) {
String msgBody = msgs[i].getMessageBody();
//String pinNo = msgBody.substring(msgBody.indexOf('"') + 1, msgBody.indexOf('"', msgBody.indexOf('"') + 2));
String pinNo = msgBody.replaceAll("[^0-9]", "");
Log.d("SMS", "From -" + msg_from + " : Body- " + msgBody);
//CodeVerification.insertCode(pinNo);
// Broadcast to Auto read Code sms
final String DISPLAY_MESSAGE_ACTION = context.getPackageName() + ".CodeSmsReceived";
Intent intentCodeSms = new Intent(DISPLAY_MESSAGE_ACTION);
intentCodeSms.putExtra("varificationCode", pinNo);
context.sendBroadcast(intentCodeSms);
}
}
} catch (Exception e) {
Log.d("Exception caught", e.getMessage());
}
}
}
}
}
I have registered this receiver in my class programmatic because i know OTP sms will come after my submit button click & i unregister it after OTP read as i dont want to trigger this receiver for every SMS by registering it in menifest.
SmsListener smsListener = new SmsListener();
try {
unregisterReceiver(smsListener);
} catch (Exception e) {
}
registerReceiver(smsListener, new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
EDIT
Put below receiver in your activity to get OTP code
final String DISPLAY_MESSAGE_ACTION = activity.getPackageName() + ".CodeSmsReceived";
try {
activity.unregisterReceiver(mHandleMessageReceiver);
} catch (Exception e) {
}
activity.registerReceiver(mHandleMessageReceiver, new IntentFilter(DISPLAY_MESSAGE_ACTION));
On receiving code below method will be called
/**
* Receiving Call Log Changed broadcast
*/
private final BroadcastReceiver mHandleMessageReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (intent != null && intent.hasExtra("varificationCode")) {
String youtOTPcode = intent.getStringExtra("varificationCode"));
}
}
};

For Marshmallow you have to ask users to give permissions. It's not given by default even if you declare it in manifest. You need to add code to get runtime permission for marshmallow devices.
For now just for checking you can go to settings --> Apps --> go to your in the list --> click on permissions --> Enable SMS permission. Then restart your app and check is it working.
Hope it will help you.

Change MyOtpActivity to
public class MyOTP extends BaseActivity{
EditText txtotp;
Button btnSubmitOtp;
private UpdateOTPReceiver mUpdateOtpReceiver;
private SMSReceiver mSmsReceiver;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_otp);
txtotp = (EditText) findViewById(R.id.txtOtp);
btnSubmitOtp = (Button) findViewById(R.id.btnSubmit);
btnSubmitOtp.setOnClickListener(this);
}
@Override
protected void onStart() {
super.onStart();
mUpdateOtpReceiver = new UpdateOTPReceiver();
registerReceiver(mUpdateOtpReceiver, new IntentFilter("UPDATE_OTP"));
registerSMSReceiver();
}
private void registerSMSReceiver() {
mSmsReceiver = new SMSReceiver();
registerReceiver(mSmsReceiver, new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
}
private class UpdateOTPReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent != null) {
String msg = intent.getStringExtra("msg");
Toast.makeText(MyOTP.this,"Message: "+msg,Toast.LENGTH_LONG).show();
}
}
}
}
}
In SmsReceiver
Public class SmsReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Bundle data = intent.getExtras();
Object[] pdus = (Object[]) data.get("pdus");
for (int i = 0; i < pdus.length; i++) {
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
String sender = smsMessage.getDisplayOriginatingAddress();
//ToDo check your sender
String messageBody = smsMessage.getDisplayMessageBody();
Intent updateTokenIntent = new Intent("UPDATE_OTP");
updateTokenIntent.putExtra("msg", getVerificationCode(messageBody));
context.sendBroadcast(updateTokenIntent);
}
}
private String getVerificationCode(String message) {
if (message == null) {
return null;
}
int index = message.indexOf("is");
int index_last_length = message.indexOf(".");
if (index != -1) {
int start = index + 3;
return message.substring(start, index_last_length);
}
return null;
}
}
