Hello I am writing an Application in which i am parsing JSON Images and then caching into SD Card.

What I want to do ?

I want to load images into GridView from JSON (by caching images into SD Card), and wanna populate GridView (no matter Internet available or not) once images already downloaded into SD Card.

What I am getting ?

I am able to cache images into SD Card, also to populate GridView, but not able to show images into GridView (if Internet not available) but images cached into SD Card

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {


        myGridView = inflater.inflate(R.layout.fragment_church_grid, container, false);                             

        if (isNetworkAvailable()) {
            new DownloadJSON().execute();
            } else {
                Toast.makeText(getActivity(), "Internet not available !", Toast.LENGTH_LONG).show();
        }

        return myGridView ;

        }

        private boolean isNetworkAvailable() {
            ConnectivityManager cm = (ConnectivityManager) getActivity().getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo info = cm.getActiveNetworkInfo();
            return (info != null);
        }

        // DownloadJSON AsyncTask
        private class DownloadJSON extends AsyncTask<Void, Void, Void> {

                    @Override
                    protected void onPreExecute() {
                        super.onPreExecute();
                        // Create a progressdialog
                        mProgressDialog = new ProgressDialog(getActivity());
                        // Set progressdialog title
                        mProgressDialog.setTitle("Church Application");
                        // Set progressdialog message
                        mProgressDialog.setMessage("Loading Images...");
                        mProgressDialog.setIndeterminate(false);
