How to retrieve data from a database and display it in textview for android? Mysql and php working

How do you display value from a database and display it in textview for android. I have got a tutorial from here for json parser and it seems to be working fine. When I have the application running, it does not load my activity to the textview, does not show my status. I have posted yesterday for fault exception and I was helped. THe activity seems to never load my data into textview. I will post up my code.
