Question

When I scan QR code it's getting a data on result.getContents but didn't pass the data on JSONObject obj just directing go on Catch block

data get pass to this line JSONObject obj = new JSONObject(result.getContents()); but when start to Debug then its not pass the data on 'obj' in above line.

here is my code :

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
        if (result != null) {
            //if qrcode has nothing in it
            if (result.getContents() == null) {
                Toast.makeText(this, "Result Not Found", Toast.LENGTH_LONG).show();
            } else {
                //if qr contains data
                try {
                    //converting the data to json
                    JSONObject obj = new JSONObject(result.getContents());
                    //setting values to textviews

                    if(obj.has("FN")) {
                        etFirstName.setText(obj.getString("FN"));
                    }
                    if(obj.has("N")) {
                        etLastName.setText(obj.getString("LN"));
                    }
                    if(obj.has("TITLE")) {
                        etTitle.setText(obj.getString("TITLE"));
                    }
                    if(obj.has("STATUS")) {
                        etStatus.setText(obj.getString("STATUS"));
                    }
                    if(obj.has("EMAIL")) {
                        etEmail.setText(obj.getString("EMAIL"));
                    }

                    }
                    if(obj.has("TEL;TYPE=cell")) {
                        etPhonePrimary.setText(obj.getString("TEL;TYPE=cell"));
                    }
                    if(obj.has("ADR;TYPE=work")) {
                        etAddressLine1.setText(obj.getString("ADR;TYPE=work"));
                    }
                    if(obj.has("Street")) {
                        etAddressLine2.setText(obj.getString("Street"));

Your data is not JSON, see what JSONLint reports on your output. The errororg.json.JSONException informs you, that in the beginning of your string, the phrase "BEGIN" is not allowed in Json.

{
    "json": "looks like this",
    "key": "value"
}

As your data seems to be vCard, you need a different parsing library, e.g. https://github.com/mangstadt/ez-vcard

String str =
"BEGIN:VCARD\r\n" +
"VERSION:4.0\r\n" +
"N:Doe;Jonathan;;Mr;\r\n" +
"FN:John Doe\r\n" +
"END:VCARD\r\n";

VCard vcard = Ezvcard.parse(str).first();
String fullName = vcard.getFormattedName().getValue();
String lastName = vcard.getStructuredName().getFamily();

So in your code snippet:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
    if (result != null) {
        //if qrcode has nothing in it
        if (result.getContents() == null) {
            Toast.makeText(this, "Result Not Found", Toast.LENGTH_LONG).show();
        } else {
            //if qr contains data
            try {
                //converting the data to vCard object
                VCard vcard = Ezvcard.parse(result.getContents()).first();
                //setting values to textviews

                // "given name" is the first name
                etFirstName.setText(vcard.getStructuredName().getGiven());

                // "family name" is the last name
                etLastName.setText(vcard.getStructuredName().getFamily());
                ...
