How to restart as an Android Dev?

Hey Folks, as the title says- need some help choosing the correct path. I'm a Frontend Engg.(3 yrs exp), I always wanted to be an Android Dev, back in 2019-2020 I grinded with Java, basic Android Concepts, Kotlin, Android Architecture Concepts etc. I learnt all these by heart and had good understanding of things. But somehow I got influenced into Frontend Development and stopped Android. Fast forward 2024, I now feel it was a wrong step, given that I had learnt so many things. I want to restart Android Development and look for some guidance and resources. Any help/guidance from Android Devs related to this would be highly appreciated. TIA
