Android : Should provide default constructor?

I have an app that I transferred to the new android studio. When I try and generate a signed apk I get this error:

Error:(24) Error: This fragment should provide a default constructor (a public constructor with no arguments) (com.example.mike.beerportfolionewicon.BarcodeFrag) [ValidFragment]

The class starts off like this:

public class BarcodeFrag extends Fragment implements ReadJSONResult.OnArticleSelectedListener {

    private ListView lv;
    View v;
    SearchView searchView;
    private SearchView mSearchView;
    private MenuItem mSearchMenuItem;
    String id;

    public BarcodeFrag(String scanContent) {
        id = scanContent;


    }

I selected an option to ignore inspection but it still will not create an apk...

Tried changing it to this, but same error:

public class BarcodeFrag extends Fragment implements ReadJSONResult.OnArticleSelectedListener {

    private ListView lv;
    View v;
    SearchView searchView;
    private SearchView mSearchView;
    private MenuItem mSearchMenuItem;
    String id;

    public BarcodeFrag(){}

    public BarcodeFrag(String scanContent) {
        id = scanContent;


    }

Actually its a different error:

Error:(35) Error: Avoid non-default constructors in fragments: use a default constructor plus Fragment#setArguments(Bundle) instead [ValidFragment]
