        String selectPhone = ContactsContract.CommonDataKinds.Phone.NUMBER + "=? AND " + ContactsContract.Data.MIMETYPE + "='"  +
                ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE + "'" + " AND " + ContactsContract.CommonDataKinds.Phone.TYPE + "=?";

        String[] phoneArgs = new String[]{oldNumber, String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)};

        if(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
                .withSelection(selectPhone, phoneArgs).equals(""))
        {
            Toast.makeText(getContext(), "MOBILE FIELD IS EMPTY", Toast.LENGTH_SHORT).show();
            phoneArgs = new String[]{oldNumber, String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_WORK)};
            if(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
                    .withSelection(selectPhone, phoneArgs).equals(""))
            {
                Toast.makeText(getContext(), "Work FIELD IS EMPTY", Toast.LENGTH_SHORT).show();

            }
            else
            {
                Toast.makeText(getContext(), "Work FIELD IS NOT EMPTY", Toast.LENGTH_SHORT).show();

                ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
                        .withSelection(selectPhone, phoneArgs)
                        .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, newNumber)
                        .build());
            }
        }
        else {
            ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
                    .withSelection(selectPhone, phoneArgs)
                    .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, newNumber)
                    .build());
        }

        getContext().getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
    }

I tried Doing But Did not Succeed..PLs Help

You need to retrieve both the contact id and contact type and use it in the update query arguments.I tried this and it worked. -

public void updateContact(String newNumber, String oldNumber) throws RemoteException, OperationApplicationException {

    // get contact type and contact id
    String contactId = null;
    int contactType = -1;
    Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(oldNumber));
    Cursor cursor = getContentResolver().query(
            uri,
            new String[]{ContactsContract.PhoneLookup._ID, ContactsContract.PhoneLookup.TYPE},
            null,
            null,
            null);

    if (cursor != null) {
        while (cursor.moveToNext()) {
            contactId = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.PhoneLookup._ID));
            contactType = cursor.getInt(cursor.getColumnIndexOrThrow(ContactsContract.PhoneLookup.TYPE));
        }
        cursor.close();
    }

    //ASSERT: @contactId alreay has a work phone number
    ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();


    String selectPhone = ContactsContract.Data.CONTACT_ID + "=? AND " + ContactsContract.Data.MIMETYPE + "='" +
            ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE + "'" + " AND " + ContactsContract.CommonDataKinds.Phone.TYPE + "=?";

    String[] phoneArgs = null;

    if (contactType == ContactsContract.CommonDataKinds.Phone.TYPE_WORK) {
        Toast.makeText(this, "MOBILE FIELD IS EMPTY", Toast.LENGTH_SHORT).show();
        phoneArgs = new String[]{contactId, String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_WORK)};
    } else if (contactType == ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE) {
        Toast.makeText(this, "Work FIELD IS EMPTY", Toast.LENGTH_SHORT).show();
        phoneArgs = new String[]{contactId, String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)};
    }
    ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
            .withSelection(selectPhone, phoneArgs)
            .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, newNumber)
            .build());


    ContentProviderResult[] contentProviderResults = this.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
    if (contentProviderResults[0].count > 0) {
        Toast.makeText(this, "Updated Contact Successfully", Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(this, "Contact could not be updated", Toast.LENGTH_SHORT).show();
    }
}

Make sure you have the permission to read and write contacts. Hope this helps !
