Amal has written a more advanced android tutorial located at https://github.com/K4KYA/MakersHelloAndroid/tree/codebar if you want to take Android even further :)
Google also has their own tutorial series at https://developer.android.com/training/basics/firstapp/index.html, which touches on some of the details and complexities of Android app development - saving data, sharing things with other apps, getting location data and other things you may want a more complex app to be able to do.
