Good Tutorial for making Android Apps?

[Johnmakuta]

I have taken a few programming courses in Java so I shouldn't have a problem with the programming part. I want to make an App that can play mp3, mp4, and open .txt files. That is literally all I want to do. I know this already exists but I thought it would be a good practice for my first lunge into App developement.

Look up a YT channel called Derek Banas, he has lots of programming tutorials, including Android app development.
