Using on newer Android Studio old library (or apply effect on text in another way) to do "Star Wars" credits style

Question

I have a newer project on Android Studio (Windows 10) that consists in a "Vader Says" inspired in "Simon Says" (Star Wars version). I have a class that manages scores and does a credits effect moving lines from bottom to top. I have been searching a way to apply the Star Wars credits that moves smaller to horizon and I only found "CreditsRoll" that have about 8 years old so it's impossible to upgrade and use lot of deprecated stuff with the actual gradle. You can check the library here:

https://github.com/frakbot/CreditsRoll

If you need something of my code I'll pleasantly share it.

Any idea of how do the effect if this library or project is too old to apply it on my project?

Thanks in advance and sorry for my english.

PS: I searched a lot in Google before asking, even tried another similar post solutions, but upgrading it's impossible as far as I know (tried commands throw cmd to upgrade but failed due too many deprecated things).
