                        Log.d(\"Object\", jsonObject.toString());
                        Log.d(\"Email\", \"+\" + object.get(\"email\"));
                        personNumber = jsonObject.getString(\"telephone\");
                        personEmail = jsonObject.getString(\"email\");

            emailPerson.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent i = new Intent(Intent.ACTION_SEND);
                    i.setData(Uri.parse(\"mailto:\"));
                    i.setType(\"plain/text\");
                    i.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] {personEmail});
                    startActivity(i);
                }
            });
            if(personEmail==null || personEmail.equals(\"\")  || personEmail.equals(\" \")){
                emailPerson.setClickable(false);
                emailPerson.setEnabled(false);
                emailPerson.setVisibility(View.GONE);
            }
            else{
                emailPerson.setEnabled(true);
                emailPerson.setClickable(true);
                emailPerson.setVisibility(View.VISIBLE);
            }

here it is working fine but this is a different table in same database . >in this table there is no hidden password field

try{
                            corporateEmail = jsonObject.getString(\"email\");
                            if(corporateEmail == null || corporateEmail.equals(\"\")){
                                emailCorporate.setVisibility(View.GONE);
                                emailCorporate.setEnabled(false);
                                emailCorporate.setClickable(false);
                            }

emailCorporate = (Button) findViewById(R.id.corporateEmail);
        emailCorporate.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(Intent.ACTION_SEND);
                i.setData(Uri.parse(\"mailto:\"));
                i.setType(\"plain/text\");
                i.putExtra(Intent.EXTRA_EMAIL, new String[] {corporateEmail});
                startActivity(i);
            }
        });

---

 private JSONObject parseObjectToJson(ParseObject parseObject) throws ParseException, JSONException, com.parse.ParseException {
        JSONObject jsonObject = new JSONObject();
        parseObject.fetchIfNeeded();
        Set<String> keys = parseObject.keySet();
        for (String key : keys) {
            Object objectValue = parseObject.get(key);
            if (objectValue instanceof ParseObject) {
                jsonObject.put(key, parseObjectToJson(parseObject.getParseObject(key)));
            } else if (objectValue instanceof ParseRelation) {
            } else {
                jsonObject.put(key, objectValue.toString());
            }
        }
        return jsonObject;
    }

if jsonObject is not null check to see if the parse database you are pulling your data from has the the "email" tag
