Converting arraylist to array
<p>I have to convert arraylist to array for <a href="http://stackoverflow.com/questions/6631424/dynamic-lazylist/6631615#6631615">this</a> thread . Its sending null , so i am wondering about that there is something not right with conversion , although i have give a direct url but still its coming with empty value . The approach i have used is this </p>

<pre><code>public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);



        ArrayList&lt;String&gt; listItems = new ArrayList&lt;String&gt;();
        try {
            URL twitter = new URL(
                    "http://midsweden.gofreeserve.com/proj/androidjson.php?identifier=123");
            URLConnection tc = twitter.openConnection();
            BufferedReader in = new BufferedReader(new InputStreamReader(
                    tc.getInputStream()));

            String line;
            while ((line = in.readLine()) != null) {
                JSONArray ja = new JSONArray(line);

                for (int i = 0; i &lt; ja.length(); i++) {
                    JSONObject jo = (JSONObject) ja.get(i);
                    listItems.add(jo.getString("http://midsweden.gofreeserve.com/proj/admin/pictures/file87619.JPG"));
                }
            }
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace(); 
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();

        }

        mStrings = listItems.toArray(new String[listItems.size()]);
         list=(ListView)findViewById(R.id.list);

        adapter=new LazyAdapter(this, mStrings);
         list.setAdapter(adapter);

         Button b=(Button)findViewById(R.id.button1);
         b.setOnClickListener(listener);
        }
