I want to try myself in mobile development for Android. Where to look?

Question

Android

Hello. I am now an upper-middle front with a touch of back (at work, it's a pure Angular front, I run my home projects as a full stack of Angular + .NET Core).
I want to try mobile development for Android. Tell me which way to look to avoid water, outdated technologies and development principles. To immediately understand how it is necessary and correctly to build the architecture of the project, how to design an interface that will definitely run on most versions of android, which is now relevant, and so on. I would be grateful for any information in Russian / English. I plan to write in Kotlin.

Answer 1

1. Outdated technologies of technologies are unlikely to be avoided by a beginner.
2. which will definitely run on most versions of android - this is not a big problem, install minSdkVersion 16, connect the androidx libraries and go, the studio itself will tell you if you use methods that are not compatible with your minSdkVersion
3. I plan to write in Kotlin - I would still advised to start with java
