Youtube API search auto-complete

How do I retrieve Youtube's autocomplete results using Jsoup (Java)?

My code JAVA :

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.toolbar_item,menu);
        MenuItem menuItem=menu.findItem(R.id.search);
        final SearchView searchView =(SearchView) menuItem.getActionView();
        searchView.setQueryHint("Search here");
        SearchView.OnQueryTextListener queryTextListener= new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {

                searchView.clearFocus();
                SongName = query;
                parseItems.clear();
                Content content = new Content();
                content.execute();
                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                return false;
            }
        };
        searchView.setOnQueryTextListener(queryTextListener);
        return super.onCreateOptionsMenu(menu);
    }
