I'm at the step where we populate the array with the json data, but the data does not display in the emulator, what i get is: " No item to display.

public void updateList() {
      if (mBlogData == null){

    }
    else{
        try {
            JSONArray jsonPosts = mBlogData.getJSONArray("posts");
            mBlogPostTitles = new String[jsonPosts.length()];
            for(int i = 0; i < jsonPosts.length(); i++){
                JSONObject post = jsonPosts.getJSONObject(i);
                String title = post.getString("title");
                title = Html.fromHtml(title).toString();
                mBlogPostTitles[i] = title;
            }
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                    android.R.layout.simple_list_item_1, mBlogPostTitles);
            setListAdapter(adapter);
