Implementing Picasso not loading image

After I decided to implement Universal Image Loader, because I had implemented a method that convert URL to Drawable, but since I don't know how many images it will return my SQLite query I decided to implement an Image Loader... The thing is I'm stuck at the moment, cause I thought I did all what the GitHub say but at the time I load the Image it stays white and never loads.

On my Adapter class I've changed the line of the drawable as :

Picasso.with(context)
            .load(Uri.parse(String.valueOf(item.icon)))
            .resize(180, 180)
            .placeholder(R.drawable.ic_launcher).into(viewHolder.ivIcon);

It works, beucase it shows yo me the ic_launcher icon... but never changes to the real image.

On my class where I fetch the data I have this (on my OnCreate()) :

   new Thread(new Runnable() {
                @Override
                public void run() {
                    try {
                        Thread.sleep(2000);


                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }

                    new MyAsyncTask().execute();

                    getActivity().runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                    //   progress.dismiss();
                        }
                    });
                }

            }).start();
        }

Then I created an inner class where I fetch the data into my ListView... but it doesn't works. I don't know If I've to delte those methods since I've changed it to Picasso.

private class MyAsyncTask extends AsyncTask<Void, Void, Void> {
    @Override
    protected void onPreExecute() {
    }

    @Override
    protected Void doInBackground(Void... params) {

        Conexion = new MarketSQLite(getActivity(), "market", null, 1);
        mItems = new ArrayList<ListViewItem>();

        db = Conexion.getReadableDatabase();

        Cursor c;

        c = db.rawQuery("Select NOM_OFER,PREU_OFERTA,DATA_F,FOTO,PERCENTDESCOMPTE from T_OFERTA", null);
        c.moveToFirst();
        if (c != null) {
            do {
                for (int i = 0; i < c.getColumnCount(); i++) {
                    Title = c.getString((c.getColumnIndex("NOM_OFER")));
                    Preu = c.getColumnIndex("PREU_OFERTA");
                    percent = c.getString((c.getColumnIndex("PERCENTDESCOMPTE")));
                    data_f = c.getString((c.getColumnIndex("DATA_F")));
                    URLTest = c.getString((c.getColumnIndex("FOTO")));
                    FOTO = Imagehandler(URLTest);
                    Log.e("", "" + c.getString(i));

                    // initialize and set the list adapter


                   // Toast.makeText(getActivity(), "Title" + Title + "Preu" + Preu + "Percent" + percent + "Cheese is " + data_f, Toast.LENGTH_LONG).show();
                }
                mItems.add(new ListViewItem(FOTO, Title, Preu.toString(), percent, data_f));


            }while (c.moveToNext());
        }
        c.close();

return null;
    }


    @Override
    protected void onPostExecute(Void result) {
        super.onPostExecute(result);
        myAdapter = new ListViewDemoAdapter(getActivity(), mItems);
        setListAdapter(myAdapter);
    }
}

Where ImageHandler is a method that I've created before this is :

 protected Drawable Imagehandler(String url) {
        try {
            url=url.replaceAll(" ", "%20");
            InputStream is = (InputStream)this.fetch(url);
            Drawable d = Drawable.createFromStream(is, "src");
            return d;
        } catch (MalformedURLException e)
        {
            System.out.println(url);
            System.out.println("error at URI"+e);
            return null;
        }
        catch (IOException e)
        {
            System.out.println("io exception: "+e);
            System.out.println("Image NOT FOUND");
            return null;
        }
    }

    protected Object fetch(String address) throws MalformedURLException,IOException {
        URL url = new URL(address);
        Object content = url.getContent();
        return content;
    }

I don't know why is loading my image on my ListView if it shows all of the rest of data...
