How to show Only if phone Number is present using contactpicker

Question

I am using Contact picker library for selecting multiple contacts but if a contact doesn't contain any number and if it is selected then it is showing some null pointer exception in the edit text field. How to remove that message and also how to remove trailing comma. Below is my Code.

 try {
            int pos = 0;
            for (Contact contact : contacts) {
                String displayName = contact.getDisplayName();
                result.append(displayName + ",");
                result.setSpan(new BulletSpan(15), pos, pos + displayName.length() + 1, Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
                //pos += displayName.length() + 1;
            }
        }
        catch (Exception e) {
            result.append(e.getMessage());
        }

        contactsView.setText(result);

please try to check this code

 void getAllContacts() {
    ArrayList<String> nameList = new ArrayList<>();
    ArrayList<String> numberList = new ArrayList<>();

    Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
    String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER;
    String[] list = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone._ID, ContactsContract.Contacts._ID};
    Cursor cursor = getContentResolver().query(uri, list, selection, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");

    cursor.moveToFirst();
    if (cursor.moveToFirst()) {
        do {
            String contactNumber =     cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));


            contactNuber.add(contactNumber);
            contactsName.add(contactName);
            nameList.add(contactName);
            numberList.add(contactNumber);

        } while (cursor.moveToNext());
        cursor.close();
        myContacts.put("name", nameList);
        myContacts.put("number", numberList);


    }
