Android development tools in 2019?

Question

Android

Hello!
The question, in fact, is expressed in the topic: what tools are used for android development in 2019?
I work as a backend developer in java/kotlin with many related frameworks used in the bloody interface. I decided to try writing an application for my smartphone, but somehow even in a stupor what tools to use in addition to the obvious android studio and kotlin, I can’t write everything manually. Yes, you can search for articles, but absolutely most of the articles that are on the first request that came to mind were written several (4 or more) years ago, which gives reason to doubt their relevance.
Are there any analogues of the same spring, which are de facto standards in the world of android development (who rules the ball in DI for android)? Any ui kits similar to hibernate? What should be used to make development as easy as possible?

Answer 1

Android Studio
MVP/MVVM (architecture)
Dagger (DI)
Retrofit(rest client)
Glide/picasso (pictures)
Gson(json)
Espresso (tests)
Firebase (baas)

Answer 2

Android Studio, no options.
There is also Eclipse, but it is buggy and few people work on it now.
A Xamarin allows you to write applications for Android in C #
In Android, Dagger2 rules the DI ball

Answer 3

Yes, you can: I

For yours, it’s more suitable like this, simpler: https://jsfiddle.net/Ankhena/L8myb66u/
ps and you don’t need to use fieldset, not by purpose and where it can be dispensed with.

make a title with white background and circle pseudo-elements and position it on top of the frame
