android - how to fetch data from a database online

Question

I have a layout.xml in which when I click a button, the app looks for data on an online database. Imagine an app that goes on a DB online to see how many items are left for online purchases.

Now, I set the check for internet connectivity, I can set an action through the onClick class and I use the HttpGet but, how do I look for an information in a database online? Is there any ID for this item, or parameters to be used? How did you set your database, so as to be used to let information be found?

Thanks in advance!

If you are talking about using your own or creating your own database, you can create a MySQL Database and write tables for your items. Then search, filter, add and delete items in your table using SQL queries.

You can also check out Parse which is a backend service with an Android SDK that allows you to store items and data online in the cloud.
