Listen Outgoing Sms or Sent Box in Android

Listen outgoing SMS or sent box in Android

Basically, you have to register a content observer... something like this:

ContentResolver contentResolver = context.getContentResolver();
contentResolver.registerContentObserver(Uri.parse("content://sms/out"),true, yourObserver);

yourObserver is an object (new YourObserver(new Handler())) that could look like this:

class YourObserver extends ContentObserver {

    public YourObserver(Handler handler) {
        super(handler);
    }

    @Override
    public void onChange(boolean selfChange) {
        super.onChange(selfChange);
        // save the message to the SD card here
    }
}

So, how exactly do you get the content of the SMS? You must use a Cursor:

// save the message to the SD card here
Uri uriSMSURI = Uri.parse("content://sms/out");
Cursor cur = this.getContentResolver().query(uriSMSURI, null, null, null, null);
 // this will make it point to the first record, which is the last SMS sent
cur.moveToNext();
String content = cur.getString(cur.getColumnIndex("body"));
// use cur.getColumnNames() to get a list of all available columns...
// each field that compounds a SMS is represented by a column (phone number, status, etc.)
// then just save all data you want to the SDcard :)

Android: Is there any way to listen outgoing sms?

You will have to do something like this:

1. Cache all messages's hash code on the phone
2. Register an content observer for content://sms
3. In onChange method of observer, enumrate all messages to check if it is in cache, if not, the message is sent out just now.

Good luck with your project :-)

Edit: md5 method
You can take the (arrival date + message) text to get a unique md5 output.

private String md5(String in) {
    MessageDigest digest;
    try {
        digest = MessageDigest.getInstance("MD5");
        digest.reset();        
        digest.update(in.getBytes());
        byte[] a = digest.digest();
        int len = a.length;
        StringBuilder sb = new StringBuilder(len << 1);
        for (int i = 0; i < len; i++) {
            sb.append(Character.forDigit((a[i] & 0xf0) >> 4, 16));
            sb.append(Character.forDigit(a[i] & 0x0f, 16));
        }
        return sb.toString();
    } catch (NoSuchAlgorithmException e) { e.printStackTrace(); }
    return null;
}

Listening to outgoing sms not working android

In addition to the silly mistake on my part that @CommonsWare pointed out, me missing

@Override
public void onCreate() {
    super.onCreate();

    ContentResolver contentResolver = this.getContentResolver();
    contentResolver.registerContentObserver(Uri.parse("content://sms/out"),true, new SmsObserver(new Handler()));
}

the other issue was actually in these two lines

contentResolver.registerContentObserver(Uri.parse("content:&‌​#47;/sms/out‌​"),true, new SmsObserver(new Handler()));

and

Uri uriSMSURI = Uri.parse("content://sms/out");

where I changed the content://sms/out to content://sms and then proceeded to check for the type to make sure the change I was getting was actually an outgoing message. I also had to make sure to check for multiple calls like so:

if (cr.getInt(cr.getColumnIndex("type")) == 2) {
    if(id != cr.getInt(cr.getColumnIndex(cr.getColumnName(0)))) {
        id = cr.getInt(cr.getColumnIndex(cr.getColumnName(0)));

        String address = cr.getString(cr.getColumnIndex("address"));
        Database.messageSent(SmsOutgoingObserver.this, address);
            Log.d("OUTGOING", address);
        } else {
            Log.d("OUTGOING", "MESSAGE ALREADY LOGGED");
        }
     };
}

and simply defined private int id = 0; as a global variable

Intercepting Outgoing SMS

Incoming SMS

You can intercept an incoming sms thru sms listener using Broadcast receiver.You can modify the incoming sms or destroy it so that it does not reaches inbox.

Outgoing SMS

You can listen for outgoing sms by putting content observer over content://sms/out but you can not modify it with the native sms app.You can obviously modify the content of content://sms/out but it has no point.

Receive broadcast when send an sms

I found the answer

public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(VIEW_RESOURCE_ID);

                SendSmsObserver smsObeserver = (new SendSmsObserver(new Handler()));
                ContentResolver contentResolver = this.getContentResolver();
                contentResolver.registerContentObserver(Uri.parse("content://sms"),true, smsObeserver);
            }

        public class SendSmsObserver extends ContentObserver {

                public SendSmsObserver(Handler handler) {
                    super(handler);
                }

                @Override
                public void onChange(boolean selfChange) {
                    super.onChange(selfChange);
                    // save the message to the SD card here

                     Log.d("sent sms", "one text send");

                }
            }
