Android. A public constructor with no arguments

When i try to export this project to my android device, there is a problem occur in my constructor that used for custom cursor adapter... Anyone can tell me why this occur?

 *My CursorAdapterActivity.java
public class CursorAdapterActivity extends CursorAdapter {

   public CursorAdapterActivity(Context context, Cursor c) {
            super(context, c);
   }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        // when the view will be created for first time,
        // we need to tell the adapters, how each item will look
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View retView = inflater.inflate(R.layout.list_shipments, parent, false);

        return retView;
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {

        //Assign data to each textview in list_shipments.xml
        TextView tvClientReferenceNo = (TextView) view.findViewById(R.id.tv_client_reference_no);
        tvClientReferenceNo.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(2))));

        TextView tvContactPerson = (TextView) view.findViewById(R.id.tv_contactPersonNno);
        tvContactPerson.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(7))) + " (" + cursor.getString(cursor.getColumnIndex(cursor.getColumnName(6)))+")");

        TextView tvDestinationName = (TextView) view.findViewById(R.id.tv_destinationName);  
        tvDestinationName.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(8))));


    }
