View pdfs stored in assets folder from listview click in fragment

问题

I have created a ListView in which I would like each item to open a certain .pdf file located in assets/PDFS folder located within my Android App. The following code does not throw any errors, but does not open the file either. Can someone share an idea for the solution?

Note that I am using Fragment

public class FreshFragment extends Fragment implements OnItemClickListener {

    ListView lv;
    String[] titles;

    public FreshFragment() {

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View V = inflater.inflate(R.layout.fragment_fresh, container, false);


        lv = (ListView)V.findViewById(android.R.id.list);
        lv.setOnItemClickListener(this);

        return V;
    }

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        switch (position) {
        case 0:
            File pdfFile = new File("res/assets/peedee.pdf");
            Uri path = Uri.fromFile(pdfFile);
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(path, "application/pdf");
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            break;

        }
    }
}

You can't open a file in your assets in another app. You need to write it to disk somewhere both apps can read it first, such as external storage.
