What technologies for creating android applications are now in vogue?

Question

Java

Is andr.studio+java still alive (or better kotlin), which is better when compared to xamarin, react native, etc. I heard that sharp + unity is popular for mobile development, right? In general, I decided to join this area, what technologies do you recommend me to study (entry threshold, market entry)? The plans are to develop simple applications like - apps for training (100otzh, etc.), some kind of news feeds, epub readers, pdf, etc.

Answer 1

Good afternoon!
Well, to answer your question more correctly, you need to clarify that applications can be native and non-native. Native applications are written in Kotlin or Java (you can choose any IDE, be it Android Studio or Intellij IDEA, etc.). Native applications, unlike others, can use all the features of the Anroid API, while non-native ones are basically limited. On the other hand, the development of non-native applications is relatively cheaper than native ones. + you can provide cross-platform (Android, iOS) on the same React Native.

Is andr.studio+java still alive (or better kotlin), which is better when compared to xamarin, react native, etc.

Yes, java & kotlin are alive and well) To the question of what is better here, everyone chooses for their task. I want cheaper and faster and, in principle, not very demanding applications, then React Native. If you want native applications, then Kotlin | Java.

I heard that sharp + unity is popular for mobile development, right?

No, but you can also write an application in C# using Xamarin.

In general, I decided to join this area, what technologies do you recommend me to study (entry threshold, market entry)?

Well, if you want to go into mobile development, then learn Kotlin. + knowledge of Java is recommended.
As for me, learning React Native is only for mobile. development is meaningless. IMHO, if you choose react, then you need to go to the front-end and learn react native as an addition.

The plans are to develop simple applications like - apps for training (100otzh, etc.), some kind of news feeds, epub readers, pdf, etc.

The applications you listed are not that demanding and can be developed on anything.
You can also write in flutter. It seems to be written in Dart.
It seems to me that java / kotlin is easier than js for a beginner and, accordingly, it is better to start with them ...

Answer 2

Java and Kotlin are alive and not going to die.
C# and Unity are for games.
