I am thinking to develop an android app for our organization and I want to connect to my website's database using the app, how to securely make a connection between app and website database in my VPS. 
I would like to know if anyone could help me to start with.

Hey. there are loads of great online video lectures that teach you all that. you could just learn from them. If you want them on your own device offline, then just download them. Torrent is the best way if you ask me. I use online tutorials a lot when I decide to learn something.

I would like a demo on how to connect to my existing database with an android app, the class file to make connection. I saw and downloaded Udemy, a mobile app to learn android app coding, but it seems a long process.

I think you can just make the connection using any database system really easily? Since you just need the database details whether it be postgres/mysql/mariadb/mongo etc. Or you can make it through the api backends, although that is way advance but there's loads of tutorial online either way.

@Littlemaster You may write a simple php code connecting to your database and run it in your VPS, which should output what you want upon query in json format.

Then from your Android app using HttpsURLConnection to get and then parse your json data.

Did you check Youtube ? These days it has more tutorials about everything than anywhere else. I also downloaded bunch of Android related tutorials last year which were a great help. There are some really good basic tutorials about app development. Im sure now there are more new tutorials.
