I'm getting "Title" in my blog app instead of the actual titles

Not sure what I'm doing wrong here. Here's my code:

package com.K2.blogreader;

            getBlogPostsTask.execute();
        }
        else {
            Toast.makeText(this, "Network is unavailable!", Toast.LENGTH_LONG).show();

I know this is a lot to look over but is there anyone on the staff or something that can help me with this? I can't advance until I get this figured out.

Your problem is in this line:

title = Html.fromHtml("title").toString();

You are passing in the string "title", which is being converted to....."title". :) You just want to pass in the variable instead.

Thank you, thank you so very much. I guess this is my first programmers experience where I look for days for the mistake I made, only for it to be the smallest thing.
