This tutorial builds on tutorial 21. We take our JSON result array to build an ArrayList with our custom class, rather than a String. This allows us to do more useful things with the structured data our remote url returns to our application. We also bring back our ArrayAdapter and ViewHolder technique, with a slight modification to work with our new ArrayList.

This tutorial is our first tutorial that deals JSON handling in an Android application.  We pull a json encoded array from a URL, and display it in our textview, using the JSONArray and JSONOBject Classes.  This tutorial is very similar to 20, as we use the same basic series of classes to get our data from the internet.

This tutorial shows you how to overwrite a database file with another database file using the onUpgrade method. This is NOT the prefered way to do this, as you will lose any data your application’s users have put in their database (DUH) BUT…If your application does not write to the database, you can get away with this.

In this tutorial, we add the ability to delete a selected entry from our database. The user must first click the item from the list, then click the on delete button. If the user clicks the delete button first without having selected an entry, nothing happens! We have retained the save and edit features from previous entries.
